define htc BC as function of Qwall in transients
In my simulation, the wall BC is heat transfer coefficient as a function of wall heat flux (boiling), htc=f(Qwall). I first ran transients with a constant htc without problem, and then used htc(Qwall) but got an overflow error. To find out what is wrong, I calculated htc as BC for the new run based on Qwall results from previous runs and it worked fine. In this way, however, htc is fixed during the transient runs. Any advice on resolving this problem? Do I need to access Qwall in CEL from previous timestep in transients?
Thanks in advance!
