Hi

I am doing some FSI integration (fluent to static structural) in ansys and I am facing a question.

What I am doing in fluent is a simulation of a liquid cooled solid that is being heat up by natural convection. Nothing very complex here.

Then I am exporting the CFD results into Static Structural.

In the problem condition there is a Environmental Temperature that I apparently have to fill out. Default is 22C. Obviously since the thermal problem has been solved by fluent, and I am only interested in the stress and deformation in the solid (resulting from the solved thermal problem) this "environmental temperature" is not desired here.

I haven't been able to disable this settings so that the problem is solved solely on the temperature map in my solid.

I have "worked" around by exporting the average temperature as a parameter in fluent, and then making the "environmental temperature" an input parameter. And linking both in workbench, that way the environmental temperature is much closer to the actual solid temperature map, however, since I am looking at extremely small deformation (of the order of E-8), even small difference on the temperature have a huge impact on the results.


is there a way to disable this environmental temperature setting in static structural?

thanks
Steve
