Mesh generator interfaces

The mesh generator interface is responsible to provide a link to specific mesh generator. The supported values of meshpackage parameter are

• MPT_T3D: meshpackage = 0. T3d mesh interface. Default. Supports both 1d, 2d (triangles) and 3d (tetrahedras) meshes. Reliable.
• MPT_TARGE2: meshpackage = 1. Interface to Targe2 2D mesh generator.
• MPT_SUBDIVISION: meshpackage=3. Built-in subdivision algorithm. Supports triangular 2D and tetrahedral 3D meshes. Can operate in parallel mode.
