- Less looping when detecting lagrangian clouds and their fields. - Avoid using Time::setTime() and IOobjectList in tight loops. They both kill performance immensely. ENH: provide a -noLagrangian option to foamToEnsight and foamToEnsightParts for even more control.

Description
|
|
Translates OpenFOAM data to EnSight format.
|
|
|
|
An Ensight part is created for the internalMesh and for each patch.
|
|
|
|
Usage
|
|
- foamToEnsight [OPTION] \n
|
|
Translates OpenFOAM data to EnSight format
|
|
|
|
\param -ascii \n
|
|
Write Ensight data in ASCII format instead of "C Binary"
|
|
|
|
\param -noZero \n
|
|
Exclude the often incomplete initial conditions.
|
|
|
|
\param -noLagrangian \n
|
|
Suppress writing lagrangian positions and fields.
|
|
|
|
\param -noPatches \n
|
|
Suppress writing any patches.
|
|
|
|
\param -patches patchList \n
|
|
Specify particular patches to write.
|
|
Specifying an empty list suppresses writing the internalMesh.
|
|
|
|
\param -faceZones zoneList \n
|
|
Specify faceZones to write, with wildcards
|
|
|
|
\param -cellZone zoneName \n
|
|
Specify single cellZone to write (not lagrangian)
|
|
|
|
\param -width \<n\>\n
|
|
Width of EnSight data subdir (default: 8)
|
|
|
|
Note
|
|
Parallel support for cloud data is not supported
|
|
- writes to \a EnSight directory to avoid collisions with foamToEnsightParts
