floating point error with sutherland transport #79

Closed omriseemann closed 1 year ago

omriseemann commented 1 year ago

Hi, I am heaving an issue running a standard 1D blast case with 2 phases and basic perfectGas model but with sutherland transport. After half the runtime, the code crash with floating point error. The crash is related to physics parameters used, if I change the transport coefficients to be either much higher or much lower it will not crash. I have attached the case. I would be grateful for help and advice. Thanks.

did you get to solve the floating points error? if so, could you please share how did you solve it?
