Thermal analysis, structural analysis

(OP)
Hello
Can anyone help me to make a thermal analysis for a cross section and afterward make a structural analysis of a beam, taking into consideration the temperature distribution from the thermal analysis?

Thank you

RE: Thermal analysis, structural analysis

That is very common. Are you using ANSYS APDL? If so, look into the BFINT command. I suppose the steps are as follows:
1. Build your thermal model, solve.
2. Build your structural model.
3. NWRITE the nodes from your structural model to a file (e.g. "structural_model.node")
4. Interpolate your thermal model results onto your structural model nodes with BFINT (e.g. "thermal_loads.bfin")
5. Read your interpolated temperatures into your thermal model (e.g. "/input,thermal_loads,bfin")

Let me know if I've forgotten anything, but I think that's pretty much it.

Thank you for guidance
I am pretty new in Ansys and I have to figure it out how to do that.
Moreover I have to figure out how to use Beam24 element.

If you have any advice or references where I can see the steps for input files, please let me know.

If I will succed with the model I will tell you if there is anything missing among your 5 steps:D

Thanks

RE: Thermal analysis, structural analysis

@flash3780 @bothul
I am trying to deflect the beam, by using Temp as input.
Beam 2D, patches in the middle.
In Coupled field analysis. I followed with: Temp on patches
Area1(beam), Area4,5(patches)
/Sol
DA,4,TEMP,1275
DA,5,TEMP,1275
I got deflection along x-direction, but doesn't shown in y-direction. why?? should i use some other than DA?
or should i change temp gradient direction, how to change gradient ?

Thank you very much
