WIND (unstructured) export supports 3D unstructured grids. Either Single or Double precision can be used for export.
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.
Note that more WIND (unstructured) solver attributes are available in CAE, Solver Attributes, WIND
