An transient problem cannot convergence.
What should I do next? How to modify the model? |

Hey Kevin,
I was under the impression that transient keeps changing with time : correct me if I am wrong. Is there any special case you are running? Can you explain the problem. Regards |

Hello,CHELSA ,
There are two large scale box passing each other in this case. Box is 1m*0.4m*0.3m, is filleted .The velocity of the two box is respectively 50m/s and -50m/s. It is versy simple ,but convergence is difficulty to arrive. I changed the delta time ,but it still divergenced.I 'am confused for the case,what should i do next? |

Hey Kevin,
Looks like it is a case of large tolerences. How much did you give? Try something like 0.001 or closer and also are your momentum equations converging? |
