Next, return to step 1 at m = 1 and perform all above steps on the new mesh. Stop mesh refinements if norms defined in step 3 either increase or stabilize, compared with the previous mesh. , [13]. 6 Numerical Examples In our computational studies of two-stage numerical procedure we had following goals: 26 L.
