Hello all,

I have a problem. I am quite new to COMSOL and currently trying to simulate how a Solid Oxide Fuel Cell will expand during the heating up and cooling down. So far, I have managed to find the thermal stresses induced at room temp and at the operating temperature. I am struggling with setting up the heating up and cooling down process. Could anyone please advise me?

I think there must be a function for it somewhere, I just cannot find it. I thought about using some kind of step increase function but don't know how to do that.

The heating up time is 800s and it starts at RT and finishes at 700°C.

I would like the results to show how the stress changes with time and temperature.

Thank you,

Miroslav
