Hi,

I'm working on a three-layer model where my middle domain will grow as a function of time (see the blue boundary in image), I have a problem how to find or define a physics or a method to make this middle domain grow knowing that I use the temporal solver.

You probably might employ a thermal expansion material.

Depending on the physics or mechanics that is causing the growth there may be different options. You may want to look into the options provided by the moving mesh and/or deformed mesh methods.

thank you for your reply, i have tested the defromed geometry option, i was able to move the forntier but the problem is that in the simulation there is no change it always refers to the initial domains for calculations, the domaine is not updated
