Using previously computed solution as input for new simulation.

Hello,
I am doing a stationnary study of thermal strain using the solid mechanics module. I want to simulate thermal strain in a system with different material that have been deposited at different temperatures one by one.
For that I would like to do a simulation with the first two material, then use this solution as input for the three-material case, solve it, and so on.
Is that feasible? How can I use a previous solution as inital condition? The 'initial values' condition only allows to put initial constant displacement.
Thanks for your help

Hi Léo,
In Application Libraries you can find an example of exactly this. It is called Thermal Stresses in a Layered Plate (file: layered_plate).
You can also find it here: https://www.comsol.com/model/thermal-stresses-in-a-layered-plate-273
The main idea is to use the Activation feature to activate the layers one by one as they are deposited.
