Description
|
|
Writes out the FOAM mesh in pro-STAR (v4) bnd/cel/vrt format.
|
|
|
|
Alternatively, extracts the surface of the FOAM mesh into
|
|
pro-STAR (v4) .cel/.vrt/ format.
|
|
This can be useful, for example, for surface morphing in an external
|
|
package.
|
|
|
|
The cellTableId and cellTable information are used (if available).
|
|
Otherwise the cellZones are used (if available).
