Thank you so much, this is very helpful. I have a couple of follow up questions to solve my problem:

-       1. I did a thermal analysis and I want to import the thermal strains (not plastic or elastic) as my initial condition. The option you explained only let me import plastic or elastic strains as initial strains. Is there any way to map thermal or total strains? I need EPTT or EPTH’s 6 components instead of EPEL’s or EPPL’s. Because my EPEL and EPPLs are zero. However, WB only gives the options plastic or elastic strains when inporting.

-       2. You said “Alternatively, you could have exported strains and inserted an initial strain in Mechanical. You should not use both since this can cause overconstraint.” However, I need both mechanical stresses (caused by expansion) as well as thermal strains as my initial conditions. Is it possible to import both?

-        3. After following what you did and importing stresses, I defined my new boundary conditions and load and ran my analysis. However, the stress-strain results I get do not start from the values imported. I would assume that at the initial time step I would see the imported value then it would change according to the load applied. However, adding boundary condition to the model immediately changes the stress-strains of all nodes. Any idea what might be the reason?
