Import Heat flux into Ansys Workbench

Riffraff · April 19, 2013, 05:10

Hello everyone,

I am trying to simulate the thermal behavior of an experimental setup using the steady state thermal solver in workbench 14. As a thermal source I can define a heat flow through a surface - the problem is that in my case I do not want a uniform distribution, but to import an nonlinear distribution from a different source.

Is this possible to achieve? I'm very new to using ANSYS, thank you for any help.

Best regards,
Raphael

If you are solving a thermal problem in a solid body you can do this in ansys cfx directly. Look up conjugate heat transfer in CFX. You can specify a cfx domain to be a solid and associate thermal properties with it. Then solve both the solid and fluid domains at the same time.

Thank you for your response dklastiwka and please excuse the long delay in answer.

I've taken a look at cfx, but I I didn't get anywhere, as it seemed to be designed for problems involving fluids.

Maybe I should make my initial problem clearer. I am trying to solve a thermal problem, where heat flows into an object through a flat, circular face. The heat flux distribution I want to consider is however rather complicated. I have the values of the heat flux at discrete points on a grid for (x,y) coordiante pairs. What I need now is a way to take this discrete distribution, interpolate it if necessary and then use it as a heat source in my model.

Thank you and best regards,
Raphael
