Temperature Result not equal to Temperature Boundary Condition

Temperature Result not equal to Temperature Boundary Condition

Temperature Result not equal to Temperature Boundary Condition

(OP)
I have a complex model with contact. I set one face to a boundary temperature and I have heat flow (Watts) on a few other faces. The problem solves but the results show that face with the temeprature constraint is equal to a different value than what was set. I am refining the mesh and rerunning it. Does anyone have experience with this type of problem and what causes it?

(OP)
It turned out it was some sort of graphics error in workbench. When I probed the surface with the temperature constraint, the value was correct.  

RE: Temperature Result not equal to Temperature Boundary Condition

As far as my understanding of problem which you have stated is that you are using one heat source like a lamp. If so please specify the problem in detail because I am also doing the same kind of analysis. So I can help you out in it.

RE: Temperature Result not equal to Temperature Boundary Condition

(OP)
I'm not sure what you are talking about. I have multiple heat sources and one single boundary condition. Basically, it is three plates stacked on top of each other with several PCBs mounted on standoffs above it. The bottom plate has the temperature constraint on it.

My issue is actually why workbench's scale was off.

Further investigation shows a small area (a few elements) that for some reason have a temperature lower than the boundary condition. This occurs on the middle of the three plates.
