solar air heater-disconvergence with acitivation energy EQ !

im about to modeling solar air heater,its like a rectangular dut with 2 layer of glass and metal aborber plat.Air passes above the aborber and heat up and exit thorough the other side of collector
solar ray tracing for solar flux
solidification/melting is activated
1) i solved the momentum EQ without energy EQ,and the vectors shows acceptable velocity field, but when i activate the energy EQ and radiation EQ,the continuity lost it's convergence and the velocity vectors turn to dots!
2) the quantity of radiation flux on the absorber plate does'nt match with my boundary values and is much more!
tnx to u for ur time!
