wouldn’t it be possible ot make this work by scheduling the RHS function as `GLOBAL` ? That way it would only execute once per iteration and not once per iteration per refinement level. MoL would still update the state vector for the array but b/c it initializes the RHS to zero before the `CalcRHS` schedule group the fact that the RHS routine does not run would leave the RHS unchanged \(ie 0\) and thus effectively no update would be done.
