Errors in cutting or clipping 2nd order unstructured grid
This issue was created automatically from an original Mantis Issue. Further discussion may take place here.
Cutting or clipping does not work properly for unstructured grid containing 2nd order prisms, hexahedrons and pyramids (there are missing face elements). Grid containing only 2nd order tets and mesh containing all element types but 1st order does not result in the same problem. Attached are mesh3.vtu, which is 1st order mixed mesh behaving correctly, and mesh6.vtu, 2nd order mesh with mixed elements, resulting in cutting problems.
