I am trying to simulate 3D scroll compressor and expander.
The remeshing process is not what I want, so it gives a negative volume error in first iteration for 3D. 2D https://youtu.be/MkMrTy_3OUY I have a problem with UDF file. when I rotate the orbit scroll with the DEFINE_CG_MOTION command, the meshes stretch a lot and give a negative volume error. What command will I use? DEFINE_GRID_MOTION? Why is remeshing proses not working properly? Is UDF enough for orbiting scroll only? or Do I have to make a udf file to change the nodes in fixed scroll? CAD file, mesh settings and timestep are the same as in the article. What is the mistake I made in the UDF file that the remeshing process is such nonsense. |
