class ngsPETSc.plex.MeshMapping(mesh=None, comm=MPI.COMM_WORLD, name='Default')

This class creates a mapping between Netgen/NGSolve meshes and PETSc DMPlex

Parameters:
  • mesh – the mesh object, it can be either a Netgen/NGSolve mesh or a PETSc DMPlex

  • name – the name of to be assigned to the PETSc DMPlex, by default this is set to “Default”
