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.
