Currently I'm working on a COMSOL project on geomechanics and that have two physics models of solid mechanics. And i am changing geometry by making holes in horizontal direction (representing Tunnel Excavation).
Here my problem is to change the geometry in each step, and the values in the previous step(i.e.t0-1) also must be used in another new step (t0) and so on.
If anyone could give me some suggestions on this, it would be highly appreciated!! Thanks in advance.
