1Introduction1.1Name and specifications of the programTitle:Delft3D-RGFGRIDDescription:Delft3D-RGFGRID is a program for generation and manipulationof curvilinear grids for Delft3D-FLOW and Delft3D-WA VE. Theco-ordinate system may be Cartesian or spherical.Delft3D-FLOW is a simulation program for hydrodynamic flowsand transports in 2 and 3 dimensions, see (WL | Delft Hydraulics,2006a). One of the wave modules in Delft3D-WA VE is SWANwhich is a wave energy simulation package, see (Delft Universityof Technology, 2000).Special facilities: sketch of coarse grid using splinessmooth refinement moduleorthogonalisation modulegrid property assessmentvarious grid manipulation optionsgrid design by bathymetry or polygon controlCartesian or spherical co-ordinatescoupling of multi-domain gridsdynamic memory allocation1.2Manual versions and revisionsA manual applies to a certain release of the related numerical program. This manual appliesto Delft3D-RGFGRID version 4.15.01.The manual version number and its release date are given in the page header. Revisions to (apart of) this manual will be indicated by a version number followed by the revision numberseparated by a dot. So, version 4.12.02 is the second revision of version 4.12 of that page,section or chapter. The version number is increased when the entire manual is upgraded.1.3T ypographical conventionsThroughout this manual, the following conventions help you to distinguish between thedifferent elements of the text to help you learn about the Delft3D-RGFGRID grid generationprogram.WL | Delft Hydraulics1–1November, 2006Introduction Delft3D-RGFGRID Version 4.13User Manual 1–2WL | Delft Hydraulics ExampleDescription Grid and bathymetrySelect Grid programTitle of a window or sub-window.Sub-windows are displayed in the Delft3D window and can not be moved.SaveItem from a menu, title of a push button or the name of a user interface input field.Upon selecting this item, a related action will be executed.In case of an input field you are supposed to enter input data of the required format and in the required domain.<\tutorial\rgfgrid\harbour><harbour2.spl>Directory names, filenames, and pathnames are expressed between smaller than, <, and larger than, >, signs.

Finally, curvilinear grids for Delft3D-FLOW have to be orthogonal, whichsaves some computationally expensive transformation terms. Extra effort in the model set-upphase, results in faster and more accurate computations.Co-ordinate systemsThe grid system used in RGFGRID can be either Cartesian (in metres) or spherical (indecimal degrees). Cartesian co-ordinates can be displayed on a screen directly, just using ascale factor. Spherical co-ordinates can be displayed on screen as plane co-ordinates or asprojected co-ordinates. Plane co-ordinates on screen give distortion in the polar direction.Depending on the type of projection, projected co-ordinates have no distortion in distance andangles. For this reason a stereographic projection is used in RGFGRID.At the start of the program, you have to select a co-ordinate system. The co-ordiinates of allobjects (land boundary, grid, samples,, etc., are then in the selected co-ordinate system. Whenopening objects, RGFGRID will not check the co-ordinate system of the imported data. Atthis moment this is the responsibility of the user.ConsiderationsDelft3D-RGFGRID is designed to create grids with minimum effort, fulfilling therequirements of smoothness and orthogonality. The program allows for an iterative gridgeneration process, starting with a rough sketch of the grid by splines. Then, the splines aretransformed into a grid, which can be smoothly refined by the program. Whenever necessary,you can orthogonalise the grid in order to fulfil the Delft3D-FLOW requirement oforthogonality.V arious grid manipulation options are provided in order to put the grid lines in the rightposition with the right resolution. For instance, a grid line can be 'snapped' to a landboundary. The surrounding grid smoothly follows. More detail is brought into the grid afterevery refinement step.November, 2006Introduction to Delft-RGFGRID Delft3D-RGFGRID Version 4.13User Manual Existing grids may be modified or extended using this program. Grids can be locally refinedby insertion of grid lines. The resulting local 'jump' in grid sizes can be smoothed by a so-called 'line smoothing'.Bathymetry data can be displayed on the screen, so that internal gullies can be taken intoaccount while drawing the design grid. Existing model grids can be opened and displayed onthe screen, while creating new grids to be pasted later to the original. Before each modification or edit action, the grid is saved to the so-called 'previous state' grid. Pressing Escafter an edit action, or selecting Operations,Undo, copies the previous state grid back to thegrid. If desired, the previous state grid can be displayed together with the actual grid.Grid properties such as smoothness, resolution, orthogonality etc, can be displayed to checkthe grid quality. Graphical output can easily be created in various formats.Delft3D-RGFGRID Getting started November, 2006 User Manual Version 4.13 3Getting started3.1Overview of Delft3DThe Delft3D program suite is composed of a set of modules (components) each of whichcovers a certain range of aspects of a research or engineering problem. Each module can beexecuted independently or in combination with one or more other modules. The informationexchange between modules is provided automatically by means of a so-called communicationfile; each module writes results required by another module to this communication file andreads from this file the information required from other modules. Other, module-specific, filescontain results of a computation and are used for visualisation and animation of results.Delft3D is provided with a menu shell through which you can access the various modules. Inthis chapter we will guide you through some of the input screens to get the look-and-feel ofthe program. In Chapter 6 you will learn to generate a grid.3.2Starting Delft3DTo start Delft3D:On an MS Windows platform: select Delft3D in the Applications menu or click on the Delft3D icon on the desktop.On Linux and UNIX machines: type delft3d-menu on the command line.Next the title window of Delft3D is displayed, Figure 3-1:Figure 3-1 Title window of Delft3DNovember, 2006Getting started Delft3D-RGFGRID Version 4.13User Manual After a short while the main window of the Delft3D-MENU appears, Figure 3-2.Figure 3-2 Main window Delft3D-MENUWhether or not you may use specific Delft3D modules and features depends on the licensefile you have.
