Subject: Re: meshing problem Author: Rick Fischer Date: 2002-07-18 14:13:00The MOPT command I think is supposed to allow you to change the rate at which the mesh gets coarser. Parameters like TRANS and EXPND will control how the mesh develops. Also, you can change to alternate meshers that might behave differently. I would definately use LESIZE to specify mesh densities on all edges. A brute force logic approach would be to switch to map meshing, use lesize to set mesh densities on all four sides, mesh with quads, and then convert the quads to tris. This will give elements shaped like right triangle, and could lead to aspect ratio problems. A last ditch approach would be to mesh it uniformly coarse, the use erefine or nrefine on selected nodes or elements to gradually refine the mesh.

Hi Could someone please help me.
I'm meshing a 2D rectangular area with triangular 3 node elements with a Free mesh. I want a uniform distribution of elements sizes from a constant size at one end to a greater constant size at the other end. How do I control the rate of element growth in one direction only.
