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.
Caution: The presence of pole connectors and pole domains in structured blocks can result in degenerate hexahedral cells when exporting to an unstructured CAE format. Please refer to the Collapsed Cell Types section of this User Manual for more information on which structured topologies result in unsupported cell types.
Either the ASCII or Binary file formats and Single precision can be used for export.
