Input Arguments

dm - DM to be used with TS Many br
func - RHS function evaluation function, see TSSetRHSFunction() for calling sequence Many br

TSSetRSHFunction() is normally used, but it calls this function internally because the user context is actually Many brassociated with the DM. This makes the interface consistent regardless of whether the user interacts with a DM or Many brnot. If DM took a more central role at some later date, this could become the primary method of setting the residual. Many br
