ElementMeshRegionProduct

ElementMeshRegionProduct[mesh1,mesh2]

represents the Cartesian product of the ElementMesh mesh1 and mesh2.

Details and Options

  • ElementMeshRegionProduct is also known as outer product region or region extrusion.
  • ElementMeshRegionProduct[mesh1,mesh2] represents the region .
  • The embedding dimension of the product region is the sum of embedding dimensions, and the geometric dimension is the sum of geometric dimensions.
  • The highest product dimension supported is 3.
  • ElementMeshRegionProduct has the same options as ToElementMesh, with the following additions and changes:
  • "RegionMarkerFunction" Nonespecify region markers
