Application

ccmToFoam
|
|
|
|
Group
|
|
grpMeshConversionUtilities
|
|
|
|
Description
|
|
Reads CCM files as written by PROSTAR/STARCCM and writes an
|
|
OPENFOAM polyMesh.
|
|
|
|
Usage
|
|
\b ccmToFoam [OPTION] ccmMesh
|
|
|
|
Options:
|
|
- \par -ascii
|
|
Write in ASCII format instead of binary
|
|
|
|
- \par -export
|
|
re-export mesh in CCM format for post-processing
|
|
|
|
- \par -list
|
|
List some information about the geometry
|
|
|
|
- \par -name \<name\>
|
|
Provide alternative base name for export.
|
|
Default is <tt>meshExport</tt>.
|
|
|
|
- \par -noBaffles
|
|
Remove any baffles by merging the faces.
|
|
|
|
- \par -merge
|
|
Merge in-place interfaces
|
|
|
|
- \par -numbered
|
|
Use numbered patch/zone (not names) directly from ccm ids.
|
|
|
|
- \par -remap \<name\>
|
|
Use specified remapping dictionary instead of
|
|
<tt>constant/remapping</tt>
|
|
|
|
- \par -scale \<factor\>
|
|
Specify an alternative geometry scaling factor.
|
|
The default is \b 1 (no scaling).
|
|
|
|
- \par -solids
|
|
Treat any solid cells present just like fluid cells.
|
|
The default is to remove them.
|
|
|
|
Note
|
|
- sub-domains (fluid | solid | porosity) are stored as separate domains
|
|
within the CCM file. These are merged together to form a single mesh.
|
|
- baffles are written as interfaces for later use
|
|
|
