GMSH compound mesh
Hello everyone,
I am using GMSH for meshing. In my case I would like to simulate a single gallery excavation which means creating a cubic volume and then removing smaller volumes to simulate excavation. When I use an initial step to prestress my initial volume (before removing the first element at stage 1), I see that the different volumes that comprise my initial cubic soil do not behave as a unified volume, resulting into stress localisation.
My goal is prestress homogeneously my initial volume before I start excavating (removing elements). It seems to me that even though they define one volume, the different subvolumes behave independently. Is there a way to achieve what I want in GMSH?
