CRUNCH CFD Interface
The CRUNCH CFD translator creates the formatted input file necessary
to run the CRUNCH CFD solver.
Creating the CRUNCH CFD Input Files
The translator writes the CRUNCH CFD input files using an unstructured domain
file and, optionally, its corresponding
boundary conditions file. To create the CRUNCH CFD input files, select
the solver "CRUNCH CFD" in the "Output" menu of the ICEM CFD Mesh Editor. After
clicking "Write input" you can specify options for the interface:
select an existing unstructured domain file
select the existing boundary condition file
specify the filename base for the CRUNCH CFD input file (default is crunch_cfd.gump)
specify whether or not the grid is a moving grid.
All of the grid information is contained in the *.gump output file. The
interface generates this CRUNCH CFD file in the project's directory.
Defining Interprocessor Patches for CRUNCH CFD
To define a patch as an interprocessor patch, add a boundary condition
to the family of arbitrary name and enter as the integer value that
of the face boundary condition number (10 <= ibc_bfn <= 15).
Defining Moving Grids for CRUNCH CFD
Currently, if you'd like the patches to be written out for a moving grid,
choose the Moving Grid option in the
interface window. Also the user can specify the moving velocity in
the boundary condition menu.
Please refer to the General
Remarks section for more details on defining boundary conditions.
This interface currently supports unstructurred 3D grids.
