Structural/thermal analysis
Structural/thermal analysis
(OP)
Hello, I need to study a frame multistories structure, wich is subject to force (constant during the time) and temperatures loads that could varying during the time. I need to study the behaviour of the structure, so the stress and the deformation due to the thermal dilatation.
So I should work with a non linear analysis. The problem is that it is the first time that I work with Ansys, because usually I use other softwares. Do you think that is possible to perform a study of that kind with Ansys?
I've seen that with a Beam24 element I can use Non-linear material, and I can assign different properties at different temperatures to the plastic material (my structure is in steel), so I guess that I can perform the study.
I can treat the temperature load as force load? Can I assign to the structure step-by-step and perform the analysis in that way?
Thank you, and sorry for my bad english.

You can apply the temperature as a body load. Look at the bf command for more information. In workbench, for a static structural load you can simply insert a temperature condition. ANSYS is capable of multiple load steps.

In my model I've different kind of sections and of material that I should assign to my frame (beam) elements. Is the command sequence LSEL and after LATT the only way to work? Because my structure consists in 70k elements, and I've 20 materials and around 4k sections. The problem is that I'm going to generate an input file with a code, but if I've a lot of sections can I select with LSEL one line by one, and after assign with LATT the characteristic that I need one by one? Or do you think that the code will became very slow? Usually other FE software works in a different way, with only a command to assign to the frame the sections and materials properties. Do you have any idea?
