Comment (by Roland Haas):

Somewhat unrelated: instead of the current workaround for arrays of

The kludge was to check to see that if the "correct" component is being updated, and if not, re-write the old values of the grid array).

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.
