[petsc-dev] explicit FEM

[Mark Adams]

I am having problems with explicit + FEM. I set the DM with something like:

    ierr = DMTSSetRHSFunctionLocal(dm, DMPlexTSComputeRHSFunctionFVM,
&ctx);CHKERRQ(ierr);

But DMPlexTSComputeRHSFunctionFVM calls DMPlexComputeResidual_Internal
without a "locX_t" so there is no time derivative and so the FEM point
functions do not get a time derivative (u_t).

I'm not sure if I am missing something or if PETSc is missing this
functionality.
