How does ANSYS calculate the temperatures?
(OP)
Dear all,
I am trying to debug one of my problems (see: Thermal transient analysis with ANSYS), and I need help. Is there a possibility to exactly see the equations, matrices etc. at each node with/from which ANSYS calculates the temperatures at the nodes?
Thx

It might be worthwhile putting something like a sheet of diamond of the appropriate thickness, fixing the far side to 150ยบ, and then see what happens at the diamond/steel interface.

RE: How does ANSYS calculate the temperatures?
My guess is the stability criteria for the case of a convective boundary condition with a small mesh size implies a very small time step is neccesary- you might try the standard trick of comparing the answer for the cases of different time steps, and check to see how the answer converges toward a common answers as the time step is reduced. The stabiklity criteion is a function of the method of integration, and the ANSYS manual should provide that guidance.
