omidiut Senior Member omid Join Date: Apr 2011 Posts: 105 Rep Power: 15	Hi all I'm trying to simulate movement of a L shape in a compressible flow at Ma=0.8. Its have a 3 degree of freedom( X & Y translation and Z rotation). I like to know what is the different of simluate it by rigid body solution(beta features) or Immersed solid? Due to large displacement of the body, negative volume occurred, is there any way to solve this problem without remeshing? Best regards.
