Pleas help me!
 

hello dears
My project is the heat transfer system
But the beginning of problem solving give to me an error:
# Divergence detected in AMG solver: temperature -> Increasing relaxation sweeps!
Divergence detected in AMG solver: temperature
What should I do?
What causes it?
Thanks!

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
