It is assumed that thepiping/stress engineer has a basic understanding of the PDMS software.This manual assumes that you are working with PDMS 11.6. PSI can work with PDMS 11.5, but you will need to read the PSI 11.6 User Guide for PDMS 11.5 instead.1.2 Overview of the PSI applicationThe PSI application allows you to create stress groups from existing pipe lines within the PDMS Design application. When a stress group has been created the PSI application will create a CAESAR II CII format file, which can be selected in CAESAR II and converted to a CAESAR II_A format file. The stress engineer can then perform stress calculations on the transferredstress group.Once the stress engineer has finished the analysis; he can create a report file (with extension.out) and a CAESAR II neutral file showing the modified pipe. These files can be then be imported back into PDMS to assist the piping engineer update the PDMS model to match.22 Starting the application1. Start the Pipework Application Figure 1 is displayed.Figure 1 Pipework Application form32. Select Utilities>Pipe Stress Interface… from the main menu Figure 2.Figure 2 Utilities pull-down menu3. A Default creation Zone form is now displayed Figure 3. Select a zone in which to createyour Stress Groups from the form and press OK.Figure 3 Default Creation Zone FormIf no zone is found, a new zone should be created with its purpose set to PSI; only zones with their purpose set to PSI will be displayed in the Default Creation Zone Figure 3. (PSI is the default selection for Stress Zones; this can be modified in the PSI defaults form)Note: A Stress Group is a PDMS pipe with a list of branches to be stressed.44. The Pipe Stress Interface form should now be displayed Figure 4.Figure 4 Pipe Stress Interface Form53 The Groups Tab3.1 Creating a Stress Group1. To create a new Stress Group, press the New Stress Group button on the Pipe Stress Interface form’s Groups tab (Figure 4). A New Stress Group Name form is displayed(Figure 5); enter the name of your new stress group and press OK. To close the window without creating a new stress group select the Dismiss button.Figure 5 New Stress Group Name FormNote: Stress Group names containing slashes are not valid and will cause later problems if used.2. Once you have created a new Stress Group it will be displayed in the Existing Groups box (Figure 6) on the Pipe Stress Interface and in the Design Explorer hierarchy if displayed.Figure 6 Existing Groups Box3.2 Adding and Removing Members1. To add branches to a Stress Group, select the Stress Group you want to add to by clickingon it in the Existing Groups list and then click the Add/Remove Members button on thePipe Stress Interface. The Pipe Stress Interface now becomes greyed out and inactive.Note: The lowest level to add to a Stress Group is a branch; branches can be split if it is necessary to stress part of a branch.2. Select the branches to include in the Stress Group by graphically selecting them using theleft mouse button. Figure 7 shows the branches to include in a stress group have been selected in red. Note: This colour might vary depending upon your configuration settings.6Figure 7 Branches included in the Stress GroupTo remove a branch which you have selected, select it again and you will be prompted with a choice to remove the selected branch from the stress group. (Figure 8)Figure 8 Remove Branch dialogue3. Once you have finished selecting the branches to include in your stress group press Esc (escape). The Pipe Stress Interface form will now become active.4. The branches that you selected to include in your stress group should now be listed in the Group Members box (Figure 9). Members can be added or removed from group at anytime by pressing the Add/Remove Members button or right clicking on a Stress Group toreveal a context menu and selecting Add CE or Remove CE. See 5.1for more details.Figure 9 Group Members Box73.3 Rebuild Selected GroupThe Rebuild Selected Group button allows you to rebuild and refresh members of the currently selected group.3.4 Find a GroupThe Find Groups button allows you to determine what Stress Groups the current element belongs to. Graphically select a branch and press the Find Groups button and a form will bedisplayed that lists the Stress Groups that the branch belongs to.84 The Display Tab4.1 GraphicsThe Graphics section (Figure 10) on the Display Tab contains two radio buttons which can be toggled between; Main Nodes and Case Nodes and three check box options; Branches, Graphics and Connected which can be checked on/off.Figure 10 Graphics sectionToggling between the Main Nodes and Case Nodes (Load case nodes returned from after stressing) shows the node numbers of the respected selection in the 3D Design window. (Figure 11)Figure 11 Nodes shown on branchChecking the Branches box shows the names of the branches in the selected Stress Group in the 3D Design window. (Figure 12)9Figure 12 Branch names shownChecking the Graphics box means that all graphics are turned on. Not checking the Graphics box only shows the current Stress Group in the 3D view, i.e. all other pipes, equipment and structures are not shown (Figure 13).Current limitation: it may be necessary to use the right-button context menu item refresh toshow the current group after un-checking the Graphics boxFigure 13 Stress Group shown onlyThe Connected box turns the equipment that is connected to the Stress Group on and off in the 3D view (Figure 14).10Figure 14 Connected equipment turned on4.2 AnimationThe Animation section on the Display Tab allows you to view the processing order of the components in a Stress Group. Firstly select the Stress Group you want to view from the Existing Group box, and then press the Show button. The individual components of the selected Stress Group will be highlighted in the 3D view in the order in which they will be processed (Figure 15).Processing OrderFigure 15 Animation to show processing order of a Stress Group4.2.1 Animation SpeedThe speed at which the processing order is display in the 3D view can be controlled by the Speed track bar (Figure 16). To view the order faster slide the bar to the right, to view the order slower slide the bar to the left.11Figure 16 Speed Track Bar4.2.2 Processing OrderBranches are processed in the order in which they appear in the Group Members box. To change this processing order select the branch you want to move in the Group Members Box (Figure 9) and click on the up or down arrows (▲▼) to the right of the box.Current Limitation: the Group Members box does not always update when the up and down arrows are selected. To force an update switch to a different stress-group and back.4.3 Active Stress GroupThe original pipe is displayed by default in red and the returned stress pipe is displayed in green by default(Figure 17), but both of these can be changed in the Interface Settings.Figure 17 Returned pipe with minimal deflections12The transparency of the currently active stress group can be altered as shown in Figure 18 (It is set toSolid as default). Both the Main Group and the currently selected Load Case can be changed independently.Off removes the current active group from the 3D view.Figure 18 Display options135 Menus and Toolbars5.1 Context menusContext menu are ones that pop up when you right-click over certain items in a form. They are used to gain access to context sensitive commands. There is one context menus on the Pipe Stress Interface linked to the items in the Existing Groups box (Figure 6).Existing Group context menuRight-clicking an item in the Existing Group box i.e. the name of a Stress group brings up a context menu as shown in Figure 19 below.Figure 19 Context Menu on the Existing Group boxTable 1 below shows the context menu items and a description of their actions.Context Menu Item DescriptionDelete current Group Deletes the currently selected Stress groupShow Node Details Brings up the Show Details form as shown in Figure 20Refresh current Group Rebuilds and refreshes members of the currently selected groupTable 1 Context Menu on the Existing Group boxFigure 20 Node Details Form145.2 The Pipe Stress Interface toolbarThe PSI toolbar (Figure 21) is located under the main menu bar.Figure 21 Main menu and toolbarsEach icon on the PSI toolbar and its assigned action or purpose is listed in Table 2 below. Show Pipe Stress Interface formModify Stress Defaults (See chapter 4)Table 2 Menu Shortcut ItemsFor more information on the Pipe modification form, please refer to the Pipework Design Using PDMS User Guide5.3 The Node details formThe Node details form (Figure 20) can also be displayed by pressing the Edit Nodes button on the Output/Input tab in addition to accessing it via the Existing Group context menu.5.3.1 Display OptionsThe columns displayed on the Node Details form can be customised from the Pipe Stress Interface Defaults Form (See chapter Error! Reference source not found.).The Node Details form has two radio buttons (Figure 22). Selecting All Nodes displays all node on the form (inactive and active nodes), selecting Active Nodes just displays active nodes i.e. those nodes with a node number.Figure 22 Display Format5.3.2 Renumbering NodesNodes of a stress group can be renumbered by pressing the Renumber Nodes button located on the Node Details Form (Figure 23).15Figure 23 Node Renumbering FormSingle Node RenumberingTo renumber a single node, select the appropriate node in the list and enter a new node number in the New Number text box. Press Update Numbers to view the changes and then press Apply to save the changes.N.B If you choose a node number that is already in use then you will be asked if you want to renumber all subsequent nodes; these will be renumbered according to the increment value in the Increment text box.Cascading Node RenumberingWhen you select a node to be renumbered using the Cascade option, all subsequent nodes are also renumbered according to the increment value in the Increment text box.Reset ButtonThis resets all nodes to their original node numbers.166 Checking the Stress Group for ErrorsThe Check Group button on the Output/Input tab checks the selected Stress Group for Datacon and Node errors. When the Check group button is pressed it displays a tabbed window (Figure 24). Results from the checks are displayed under the appropriate tab.Figure 24 Pipe Stress System Errors form6.1 Datacon ErrorsThe Datacon errors tab displays Data Consistency errors for each branch in the Stress Group.6.2 Node ErrorsThe Node errors tab shows problems such as the component weight not being set. These errors should be rectified before the pipe is sent to be stressed.176.2.1 Node Errors – WeightIf the weight of a component such as an instrument is not set, then an error in the Node Errors tab will be display:Unable to Find Weight for INST /FE-117INST =15392/5691As there is no weight is the catalogue for this, it can be set locally in the design by use of a UDA (User-defined Attribute) called PSIWEIGHT. The PSIWEIGHT attribute’s value remains persistent once set and overrides the catalogue value.To set the PSIWEIGHT UDA modify the component’s attributes by selecting: Modify>Attributes from the main menu.Note: To see changes to the list of Datacon and Node Errors, refresh the Stress Group (See 5.1 Context menus) before pressing the Check Group button. This will insure that all changes to the Stress Group are up to date.Setting a temporary weight for a Stress Run1. In the Existing Group box (Figure 6), right-click on the selected stress group and select Show Node Details from the context menu. See Figure 19 for more details.2. The Node Details from will now be displayed (Figure 20).3. Locate the component that’s weight needs to be change. (If the weight is zero the Error column will be flagged as True on the Node Details form)4. Right-click anywhere on the component’s row to bring up a context menu (Figure 25).Figure 25 Display Node Attributes5. Select Display node attributes from the context menu.Alternatively press the Node Attributes button the Node Details Form.6. A form will be displayed with the majority of the fields being read-only. However if the weight is zero then the weight field can be changed. Once you have changed the weight to asuitable value, press Apply and a message will be displayed warning you that the changes made by this method are only temporary. See Figure 26.18Figure 26 Confirmation MessageNote: Further changes to weight values can be made within Caesar II.197 Pipe Stress Interface DefaultsThe PSI defaults form allows the user to configure PSI to suit the user’s project data. This can be configured in many ways so it is important to provide facilities to use this data rather than make project changes to suit PSI.The defaults file is principally used to tell PSI where to extract information and what units to expect, but it also defines how PSI works in the user environment.When the Modify Stress Defaults icon is pressed from the PSI toolbar, the StressInterface Defaults form is displayed (Figure 27).Figure 27 Stress Interface Defaults FormThe Stress Interface Defaults form has five tabs:Database UnitsInterface SettingsExpressionsRestraint DataNode Form Display ColumnsFor information on how to use the PSI defaults form, please see the PSI Admin guide.208 PDMS to CAESAR II8.1 Creating a CAESAR II Neutral fileTo create a CAESAR II Neutral file for a selected Stress Group, press the Write Data to cii file button on the Output/Input tab.It is now very important to do a Save Work immediately after creating a CAESAR Neutral File so that all data relating to the Stress Group is saved within PDMS.Once the button has been pressed three folders called input, output and logs are used to store the data. They are located in the same area as the project directories e.g.C:\ProjectPath\Project\Sampsi where the name of the project is Sam. The files contained within these folders are named according to the name given to your Stress Group. See Table 3.The input folder contains the newly created CAESAR II Neural File (*.cii) which can be input into Caesar II.The output folder contains an xml file which contains pipe stress data exported from PDMS in a predefined schema.The logs folder contains a HTML reports viewable via a web browser: _log.html which contains information about the conversion from the *.xml file to the Caesar II Neural File. The _log.html contains version information for the .cii converter, and also any messages to do with the running of the conversion process – it is a good place to look if things go wrong. It also contains information about the PDMS elements translated, and any assumptions and default values used (for example missing weights or wall thicknesses). The stress engineer may find it useful to have a look at this file.Folder Name(To CAESAR)(From PDMS)Examples offilesproducedTable 3 Input and Output Folders218.2 Converting a CAESAR II Neutral File to a CAESAR II InputfileIt is necessary to convert the neutral file created in the Pipe Stress interface to a Caesar II Input file beforethe Stress Group can be viewed and analysed in Caesar II.1. Start up Caesar II and Select Tools>External Interfaces>CAESAR II Neutral File… fromthe main menu (Figure 28).Figure 28 Tools pull-down menu2. A Neutral File Generator box should now be displayed (Figure 29). Select the first radio button labelled “Convert Neutral File to CAESAR II Input File”.3. Press the Browse button and navigate to the *.cii file in the input folder created by the Pipe Stress Interface.4. Press the Convert button. A message confirming the conversion should be displayed.22Figure 29 Neutral File Generator box8.3 Opening a CAESAR II Input FileIn Caesar II, Select File>Open… from the main menu, select the Caesar II Input File (*._A) and press Open (Figure 30).Figure 30 Opening a Caesar II Neutral FileSelect Input>Piping… from the Main menu to display the Caesar II piping input spreadsheet which contains all the information of the Stress Group created in PDMS. (Figure 31)23Figure 31 Piping Input Spreadsheet249 CAESAR II to PDMSIn order to bring back stress data from CAESAR to PDMS two CAESAR files need to be created; Report File (*.OUT) containing Displacement data for one or more Load CasesNeutral file(*.CII) of the stress pipe9.1 Creating a Report FileIn CAESAR II open the appropriate piping input file (*._A) (Figure 30) which should now be ready to be stressed and has been error checked in CAESAR. Then select Output > Static from the main menu to display the Static Output processor screen (Figure 32).Figure 32 Static Output Processor ScreenNext, select one or more load cases under Load Cases Analysed. For information on editing load cases please see the CAESAR II User Guide. Then Select Displacements under Report Optionswhich will output translations and rotations for each node. Other report options may be selected too, but are not passed back into PDMS.Note: It is important to select the 132 column report option under Miscellaneous Options rather than the standard 80 column report, otherwise PSI might encounter problems reading back the data.Note: It is advised that you don’t add the optional two title lines in CAESAR for similar reasons as above.Now save the report file File> Save.259.2 Converting a CAESAR II Input file to a CAESAR II NeutralFileIn order for PDMS to determine if any changes have been made to the stress pipe within CAESAR, the current piping input file needs to be converted to a neutral file.N.B It is important that this step is implemented either directly before the producing the report file or directly after, so that the representation of the pipe in consistent in both files.1. Select Tools>External Interfaces>CAESAR II Neutral File… from the main menu (Figure 28).2. A Neutral File Generator box should now be displayed (Figure 29). Select the second radiobutton labelled “CAESAR II Input File to Neutral File”.3. Press the Browse button and navigate to the appropriate *._A file.4. Press the Convert button. A message confirming the conversion should be displayed.9.3 Naming and location of files coming backIn order for PDMS to find the two new files from CAESAR (neutral and report) they need to be saved to the Input directory which is located in the same area as the project directories e.g.C:\ProjectPath\Project\Sampsi where the name of the project is Sam. The naming of the files is also important; the new files should have the same name as the corresponding XML file in the output folder.9.4 Getting stress data into PDMSTo get data back into PDMS, select a Stress Group from the Existing Groups box (Figure 6) which hasbeen stressed in CAESAR and has a corresponding neutral and report file in the input folder. Now press the Convert Stress Data button on the Output/Input tab. If this is successful a new XML file(StressGroupName Ret.XML) will be created and saved to the return folder.If for any reason the process fails e.g. the CAESAR report file is missing, then an error will be displayed(Figure 33).Figure 33 PSI ErrorA HTML log (*_RetLog.html) is also created and stored in the logs folder every time the Convert Outputbutton is pressed. The log gives more detail on what the conversion process has found and where, if any26problems have occurred. Any Errors will be highlighted in Red, Warnings in Blue and Restraints in green.9.5 Displaying load cases in PDMSOnce a return XML file has been created it can be opened and loaded into CAESAR by pressing the Read Stress File button on the Output/Input Tab. The return XML files should all be stored in the return folder and the file browser should automatically navigate to this.Figure 34 Load Case ModelsNote: Make sure you have the corresponding Stress Group selected in the Existing Groupsbox so that the main pipe and load case models can be shown in the 3D view.Note: You may have to re-select the Stress Group after opening the file to see the changes.The Load Case Model list should now be populated with a list of load cases; any invalid load cases will be deleted. To view different load cases overlaid on the original pipe, simply select the required load case from the list.9.6 Editing Return NodesReturn nodes can be edited by pressing the Edit Return Nodes button on the Output/Input tab. Once this button is pressed a Node Details form will be displayed containing information on the returnednodes.27Figure 35 Return Node Details FormThe return node details form includes two new columns; deflection and status. Deflections are set foractive nodes that have been stressed and have deflection data returned to PDMS. The status column isalso set for active nodes. Any new nodes will be set to “New”; deleted nodes will be set to “Deleted” andnodes which are unchanged are set to “False”.New NodesNew nodes that have been added in CAESAR e.g. an expansion loop will be displayed in PDMS as nodenumbers in space connected by a dotted line, as can be seen inFigure 36.28Figure 36 New nodes added in CAESAR and displayed in PDMS9.7 Clash checkingLoad cases can be clash checked by pressing the clasher icon on the Output/Input tab . Select theload case you want to clash check from the list of load case models and press the clasher icon. Any itemsthat clash will be added to the draw list.End of document。
