I was computing the case with a multiple-phase flow, which consists of liquid air and gas air. The temperature of working condition is very low. So the properties of liquid air and gas are defined myself. But only after 5 steps the solver will suggest the error of overflow. And in the converge figure of heat transfer, the value is up to about 1.0e08. I have tried the common ways to solve the overflow problem, but in this case I think the heat transfer is the basic problem. How can I solve it ? Help me please!
