I don't have access to Comsol 4.x. I imported a 3D mesh generated from point cloud data and generated a geometry. (A hollow almost-ellipsoid.) I solve my system on the surface/boundary alone; there is no volumetric data. I need to extract 1D data from the surface/boundary at points other than the original mesh points. The problem is that I don't know the x,y,z coords of the newly-created geometry except at the mesh points. Does anyone know how to: a) Draw a 2D plane/boundary through the 3D geometry and extract data where the 2D boundaries intercept? or b) Get creative with the post-processing tools to export these data? (These all seem to require x,y,z coords I don't have a priori.) Right now I am exporting greyscale images to image processing software and extracting intensities - very laborious and inelegant. Any thoughts? Thanks!
