Kestrel export supports 2D and 3D structured and unstructured grids. Structured blocks will be exported as unstructured hexahedra. 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: Note that more Kestrel solver attributes are available in CAE, Set Solver Attributes.
The Mesh Link frame provides options to indicate whether you wish to write out the Mesh Link and Database files during the export process in *.xml and *.nmb formats respectively. Furthermore, the Database file can be exported in either Binary (default) or ASCII format. For more information on the Mesh Link format and libraries, please visit our GitHub page: https://github.com/pointwise/MeshLink
The Database file contains all the database entities that have grid entities constrained to them. On the other hand, the Mesh Link file contains link information between the grid entities being exported and the database entities in the Database file. Checking on the Export Mesh Link and Database files options will run the Mesh Link process and export these two additional files.
When Export Mesh Link and Database files options is checked on, the Mesh Link and Database file browser buttons become enabled. These buttons will open up a file browser dialog window that will allow you to independently chose the location of the exported Mesh Link and Database files. Note that the text fields for both files are read-only; these fields will be populated with the base name selected for CAE export.
This CAE format supports high-order export up to Q2 elements. For more information on this topic, see the Grid, Elevate section of this user manual.
