How to perform a buckling analysis with thermal expansion in ANSYS Workbench Mechanical

[@Owlzon]

Thank you so much. Clearly explained everything. A new subscriber!!!!!!

Thank you for your video! What is the meaning of eigenvalues in linear buckling by temperature change? is it the factor of critical temperature buckling or the factor of thermal stress? Thanks!

Is it possible to get the models used in this demo ?

At 1:46, where exactly do you select to add the Z Vertex? And is it only on one side?

[@sourie]

In the second case, do we have to also change the linear material to a non-linear material ?

I have followed your example for second case and it seems like the pressure wasn't applied. I don't have deflection as it should be. I also got 2 warnings (solver pivot warning and large deflections activated). Can the problem be in older Ansys version?

this warning informs you that default settings are changed. You activated the large deflection so it is considered as non linear solution. solver pivot warning is there means model is not constraint properly. For solving equation, no. of variable must be equal to equations but in thermal strain we use compatibility condition means displacement is zero(or given value) in particular direction. So model must be properly constraint.

hi i change force but deplacement is the same
