What is GAMBIT?Geometry And Mesh Building Intelligent Toolkit
A single, integrated preprocessor for CFD analysis:z Geometry construction and import using:
ACIS solid modeling capabilities STEP, Parasolid, IGES etc. import (generally requires cleanup)
z Mesh generation for all FLUENT solvers including FIDAP and POLYFLOW Structured and unstructured hexahedral, tetrahedral, pyramid, and prisms.
z Mesh quality examinationz Boundary zone assignmentz Mesh export

GAMBIT Directory and Files When GAMBIT starts up, it creates a directory called GAMBIT.#
z # is a randomly assigned, four-digit process numberz GAMBIT also creates a lock file, sessionID.lok, in the working directoryz sessionID.lok prevents another user from starting up another session using
the same ID in the same directory.z If GAMBIT crashes, this file must be removed manually.
Three files are created inside the GAMBIT.# directory.The GAMBIT database. All geometry and mesh information is savedin this file. The database is often not retrievable after a crash.
sessionID.dbs
The journal file. All user instructions are stored in this file. The journal file is directly accessible from the Run Journal form.
jou
The transcript file. All output from the current GAMBIT session is stored here.

GAMBIT Directory and Files GAMBIT permanently saves these files to the working directory as sessionID.dbs, sessionID.jou, and sessionID.trn any time you issue the Save command (equivalent to any standard word processor).z The files sessionID.dbs, sessionID.jou, sessionID.trn are overwrittenz New commands are appended to the journal file, sessionID.jou.
Upon successful exit of GAMBIT :z The GAMBIT.# directory is removed.z The lock file, sessionID.lok, is deleted.
