Sequential analysis

I am going to find the temperature distribution in an object in the first step as transient solution then use the temperature as an input for the next step to find the stress distribution inside the object
my question is how I can input for example the 120th time step temperature for the corresponding 120th time step in structural analysis module?

Hi
What you can do is to solve first the temperature up to t=120, then store the solution and solve the structural
you need to define two temporal solver nodes, and select only one physics per solver (COMSOL will add a "store solution and start from initial" automatically (if no other solver has already been set up).
Better is two couple both and solve both together in one solver sequence (the solver might the real solving process separate in a segregation list, but then both are solved in sequence

Good luck
