Using variable previously computed for next simulation

I am having several difficulties trying to solve a multiphysics problem in the time domain. I have a Heat transfer model coupled with Mechanical and acoustic. At the beginnings I solve the Heat equation and then use the solution for the other two equations, but I get the error" Failed to find consistent initial values". Usually I manage to solve this kind of problem solving the static equations and using the result as initial condition. Unfortunately, in this new simulation, i wanna use the temperature solution of Thermal model found in the previous step and so I don't manage to use the static solution as initial condition. How can I solve this problem? Many thanks

Best regards

Hi

if you use the segregated solver, does this not solve the issue ? or by plying with the store solution use initial conditions from stored ?

Good luck
