Gambit neutral file format supports 2D and 3D export of structured and unstructured grids. Data is exported in double precision in ASCII format.
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.
