PETSc never conflates global and local spaces. Global vectors don't have ghost dofs and do not even know they exist. Special global vectors have a function VecGhostGetLocalForm that gets a sequential representation that includes ghost points. Those ghost points are updated by VecGhostUpdateBegin/End. _______________________________________________ fenics mailing list [email protected] http://fenicsproject.org/mailman/listinfo/fenics
