hi guys,

i am simulating heat tranasfer over a disc brake with rotating frame of reference. here i am getting the following error in the interations

temperature limited to 1.000e+0 in 10000 cells (or) temperature limited to 5.000e+3 in 10000 cells

in almost alternatively those 2 errors are coming. i am very greatful if u can solve my problem.

thanks in advance

You may just need to reduce your under-relaxations, particularly on energy.

thank you for ur response,

i've tried in that way also, but i unable to stop the same error

Is your grid boundary layer able to resolve the thermal boundary layer ?

Do you impose a flux or a temperature at the disc?
