Why do my old simulations diverge? -- CFD Online Discussion Forums

February 27, 2019, 19:46	Why do my old simulations diverge?	#1
RKE New Member RKE Join Date: Sep 2012 Posts: 21 Rep Power: 13	I have tried to use Star-CCM+ simulations which I had developed and used successfully 2-3 years ago, but they now diverge even when re-running model files and scenarios which ran well back then. I have noticed that the polyhedral mesher is no longer available for the model set-ups I use now, but I have been having problems (divergence) even with the tetrahedral mesher I now have had to use. Could anyone provide insight on what the reason for the divergence could be? Thanks in advance.
