-  !! If MVR/MVT is active, call the MVR convergence check subroutines
+  !! If MVR/MVT is active, call the MVR convergence check subroutines to force
+  !! at least 2 outer iterations. The other advanced transport packages are
+  !! solved in the matrix equations directly which means the solver is
+  !! completing the necessary checks thereby eliminating need to call package
+  !! cc routines.  That is, no need to loop over active packages and run:
+  !! call packobj%bnd_cc(iend, icnvg, hclose, rclose)
