I am working with Comsol 3.3a. I would like to solve a structural problem on a volume mesh (tetrahedrals). I have created a mesh in Matlab and I am using the Comsol scripting language in the Matlab environment. Subsequently, I export the femmesh structure to Comsol. Yet, does anyone has an idea of how to attribute certain subdomains on self-created meshes with scripting? At this moment, I only have a femmesh.</p> <p>Code (with node and elem the tetrahedral coordinates and elements): </p> <p>el = cell(1,0);<br /> el{1} = struct('type','tet','elem',elem');<br /> m = femmesh(node',el);<br /> m = meshenrich(m);<br /> fem.mesh=m;</p> <p>Furthermore, when looking at this mesh in Comsol, it looks exactly the same as the one in Matlab, yet the boundaries (faces) do not equal, i.e. they are less detailed.</p> <p>Thanks</p> <p>Jan. </p>
