Three files are created inside this directory
ident.dbs jou trn = the database. All information will be saved in this file. This file is NOT retrievable upon a crash = the journal file. This file is directly accessible from the Run journal form = the transcript file. Output from GAMBIT
Select working directory Type in Session ID or select from previous stored sessions. Startup Options
GAMBIT can be also started up from a DOS command prompt or LINUX/UNIX prompt by typing in “gambit Session Id”.
Create full geometry Decompose into mesh-able sections
Meshing
Local meshing: Edge, Boundary layers and Size Functions Global meshing: Face and/or Volume
The directory GAMBIT.# is removed The lock-file ident.lok is deleted

Batch mode (Run)
All commands processed without interruption. "read pause" command will force interrupt with resume option appearing.
# = the process number It also creates a "lock" file, ident.lok, in the working directory ident.lok prevents any user from starting up another session using the same identifier in the same directory. If the code crashes, this file needs to be manually removed.
