Hi,rnrnSo my goal is to ultimately do a multicomponent simulation. I am trying to wrap my head around the Rayleigh Taylor 3D example, and ultimately implement pressure boundaries in a geometry of my own choice. In that example, when you do superGeometry.rename(0,1), what is going on? Are the voxels having 0 values renamed to 1? So we don’t have 0 value voxels anymore? The material numbers are the same as in the cylinder3d program, right?
