songyi719 is on a distinguished road
I am currently running supersonic free stream simulation on rhocentralfoam

However, when I try to set velocity of internal field over mach 1, e.g. 1.5, It crashes with error 'Negative initial temperature' while calculating e

So, I reduced initial velocity to M 0.8, and set boundary to 1.5 so shock doesn't occur initially on the body and crash the computation, but it can slowly converge to result.

It did converge, but when I postprocess and watch it, it shows internal flow velocity is below M1 everywhere.

I set inlet to supersonicFreestream boundary condition, and outlet as inletOutlet .

Is there way to get rid of 'Negative initial temperature' problem, or make internalfield adapt to boundary condition velocity value, which is 1.5?
