TALK=T;RUN(1,1) DISPLAY This example is similar to that of case 170; but the solution procedure is elliptic rather than parabolic. Because the flow is nearly parabolic, economy is achieved by not using the whole=field solver for scalars and by setting: lithyd = 10, so that few sweeps are needed. Further economies come from setting: ISWC1 = LSWEEP and LITHC1 = LITHYD, which entail that the scalars are solved only on the last sweep and slab-wise iteration. PHOTON commands are supplied.
