Description
|
|
Translates OpenFOAM data to Ensight format.
|
|
An Ensight part is created for each cellZone and patch.
|
|
|
|
Usage
|
|
\b foamToEnsightParts [OPTION]
|
|
|
|
Options:
|
|
- \par -ascii
|
|
Write Ensight data in ASCII format instead of "C Binary"
|
|
|
|
- \par -name \<subdir\>
|
|
Define sub-directory name to use for Ensight data (default: "Ensight")
|
|
|
|
- \par -noZero
|
|
Exclude the often incomplete initial conditions.
|
|
|
|
- \par -index \<start\>
|
|
Ignore the time index contained in the time file and use a
|
|
simple indexing when creating the \c Ensight/data/######## files.
|
|
|
|
- \par -noMesh
|
|
Suppress writing the geometry. Can be useful for converting partial
|
|
results for a static geometry.
|
|
|
|
- \par -width \<n\>
|
|
Width of Ensight data subdir
|
|
|
|
Note
|
|
- no parallel data.
|
|
- writes to \a Ensight directory to avoid collisions with foamToEnsight.
