Deadly Guest Posts: n/a	DEAr Ppl, Got a question..Is it alrite to increase the momentum(under-relaxation factors) from 0.7 to 0.5 halfway through the iterations?..Would it somehow affect the temperature profile(im enabling temperature)? Cos i find that the energy iterations converged very deeply ie form 410 to the power -7 to 2 10to the power -7.. Plz shade some light on this.. Thnk you Puck
