ENH: export part information in nastran format

$FOAM_SRC/sampling/lnInclude/nastranSurfaceWriter.C

currently seems to output only one PSHELL (along with dummy values)

Is it possible to retain the geometry information?

e.g. when sampling STL or patches to output information in nastran format

MOL: change surfaceWriter api to take UnsortedMeshedSurface instead of points, faces separately. This would automatically pass in zone/tag.

probably an example for the sampling plane illustrating the data loss for part name.pitzDaily_sample.tgz

sampling geometry (plane) contains two parts, but the output contains single region with field data.

tagging in @mark

Reassigned to @mark

Milestone changed to %Version v1612

Reworked sampled surface and surface writers (and their APIs) to allow passing through of the region information, works in parallel too.

• Current producers of the region information:
  • sampledTriSurfaceMesh
• Current consumers of the region information:
  • nastran writer. The zone ids passed through as PSHELL Ids (with offset 1).

Limitations

• The per-face region association is preserved, but the face/element sort order gets lost in reconstruction. Would need to attach additional information to the sampled surface and use that for sorting, but this would also imply that sampled values be written indirectly (or resorted) too to match the order.
• Zone ids are passed through, but not their names.
• After reconstruction, zone ids are no longer contiguous. Re-sorting (as mentioned above) would solve this too, but again at the cost of more complexity when writing.
