In steady-state thermal module of ANSYS, generally, the distribution of temperature field and total-heat flux is similar. In areas with high temperatures, the driving force for heat transfer is naturally greater. For some special mechanical equipment, such as copper plate of continuous casting mold, the temperature distribution and total-heat flux distribution are completely different, with the highest temperature point and the highest heat flux density point far apart. These make the equivalent stress derived from the temperature distribution inconsistent with the actual situation. On the contrary, the distribution of total-heat flux is similar to the equivalent stress in reality.
The reason for this should be that in some special mechanical equipment, high temperature areas are separated from areas with high heat flux, resulting in different distributions of stress and temperature. I hope that ANSYS company can use total-heat flux to derive equivalent stress, abandon temperature the current method of using to derive equivalent stress.
