Using define_geom in 3D for a dynamic mesh problem

February 26, 2007, 10:57

Hi All, I would like to simulate a moving vane close to a fixed body in 3D, using a dynamic mesh UDF and remeshing. I need the surface mesh on the fixed body to 'slide' around the surface as the volume mesh remeshes, without deforming the surface. Define_geom seems the ideal way to do this to specify the surface geometry of the fixed body, but has anyone used this in 3D, to specify a complicated geometry? Any help or suggestions would be greatly appreciated. Cheers, John

Try de command DEFINE_GRID_MOTION
