DMTSCreateRHSMassMatrix

This creates the mass matrix associated with the given DM, and a solver to invert it, and stores them in the DM context.

Synopsis

#include "petscts.h" 
PetscErrorCode DMTSCreateRHSMassMatrix(DM dm)

Collective

Input Parameter

• dm - DM providing the mass matrix

Note

The idea here is that an explicit system can be given a mass matrix, based on the DM, which is inverted on the RHS at each step.
