FrontFlow export supports both structured and unstructured volume grids.
Newly created blocks are automatically assigned a VC of GRID. Blocks with
common VCs are automatically merged in the CAE file with the VC used as
the zone name. To have separate blocks written out with an assigned VC, set
a different VC to each block to avoid automatic merge. Alternatively, setting
block VCs to Unspecified will cause the blocks to be exported separately
under their block names.
Either the ASCII or Binary file formats and Single
precision can be used for export.
