Initial value of solution not respected by transient simulation

Dear forum, I want to calculate a thermal expansion problem in which I am starting from a stationary solution to run the transient model. For that, I am first running the stationary themal+structural, then the transient thermal and finally the transient structural. My problem comes when using the stationary solution as the starting point for the transient one. The thermal initial condition seems to be respected. However, the structural one is not. Interestingly, if I only run the initial step, the solution is different of what I obtain if I run and I get t=0 s of the transient solution. What could be causing this? Thank you and best regards, Eduardo

Hello Eduardo,
How did you specify your initial conditions? Did you set it for both the variables solved for and those not solved for?
