a question about generating grid used by icem
it must have the geometry model when we generate a grid with icem ,dose not it.or how can we use icem to generate a grid without geometry model?
You can either draw the geometry in ICEM or if you are really keen you can directly generate the mesh in ICEM with no underlying geometry (ie specify node locations and join nodes to make elements, then extrude/sweep/etc these to make more elements).
