Why do most of the compressible solvers diverge at flows > Ma 5? -- CFD Online Discussion Forums

February 16, 2010, 19:28	Why do most of the compressible solvers diverge at flows > Ma 5?	#1
Alan New Member Alan Harrland Join Date: Mar 2009 Posts: 21 Rep Power: 17	I am trying to model a cone in a supersonic flow field, I have attached an image of my mesh for information. I have tried to model this situation with an inlet Mach number of Ma = 7, but every solver I try diverges at these flight conditions. Below are some images from sonicFoam (ras turblence) and rhopSonicFoam (inviscid) respectively. and Why do these diverge at flows greater than Ma = 5? Can anyone help me out here please? Thanks.
