Thermal-Strcutural Analysis

Dear XANSYS members,

I am trying to simulate a thermal-structural problem of a simple structure
(two plates with different CTE's and layered on top of each other). I
intend to perform thermal analysis first then import its results into a
structural simulation. It is my first time doing something like this so I
am learning and seeking your invaluable inputs.

I understand that the element type in the thermal analysis is (SOLID226)
and the element type in the structural analysis is SOLID185.

My question is, can anyone give some insights on that? The main issue is
how to export thermal analysis results and import them into the structural
simulation. I thought of using the submodeling technique to perform this.
But I thought I should ask the experts of this community.

Does my understanding of the problem sound right? I would appreciate any
suggestions/scripts on that.

Best regards,
Mohammad

You probably already do this, but I always start into a new analysis type (or software or post processor) with an analysis I can do manually with confidence. Then I do it with ANSYS to check that I understand the effect of all the inputs and the accuracy of the solution. It's a good opportunity to fiddle around with post-processing to see how it all works and what it takes to give me the results in a convenient form. I bet you can get a student to do all the grunt-work—probably take a week or two but it'll do him/her good.
