hi
the error indicate that the energy equation diverge so you can modify the value of sweep relation factor at solution control under energy term and it can pass from 1 to 0.8 or 0.7. this problem maybe to do with the first iteration and then to vanish. or another cause is the bad setting on your boundary condition so you control another time in particular the thermal factor. i hope that it usefull |
