I recently use a CFD program to make simulation, but I found that my program is very unstable when I change some parameter, such as the grid. Mesh is the H-type, so there is not negative mesh, and the angle is not small--orthogonality is good. When I use the CFD software, there is no such problem before, and the solving speed and the convergency is both fast and good. So, I want to ask whether there is some method to make the CFD program stable. Is there paper to solve such problems? Thanks! Garry
