Hi, I am running rhoCentralFoam for supersonic case, and experiencing same problem about rhoE constantly.

While running solver, it crashes immediately, or after few seconds. I have tried several different ways to stabilize it (e.g. lower dt, Co) but it didn't work well

When problems occur in same value everytime, it means there must be some problem to it, but I cannot find out why.

What would be the problem??

Below is the error log

What could be the solution??

HTML Code:
deltaT = 4.99366e-07
Mean and max Courant Numbers = 0.00269791 0.298293
Time = 4.25729e-05s

diagonal:  Solving for rho, Initial residual = 0, Final residual = 0, No Iterations 0
diagonal:  Solving for rhoUx, Initial residual = 0, Final residual = 0, No Iterations 0

Problem solved!
I reduced maxCo and timestep
