Hello Community,

I am trying to run a new solver I made (with a new wall function as well) and in my first run attempt after I compiled it, an error was produced. I am new to OF (but learning fast!) so I am not sure how to read this just yet. That is the insight I am looking for. I would like to know where to look for the cause of this error.

My guess to this matter is that after 23 iterations the calculation of p_rgh caused this issue. Is that correct?

Any other insights would be most appreciated.

Code:

PIMPLE: Operating solver in PISO mode


Starting time loop

Time = 2

Courant Number mean: 0 max: 0
DILUPBiCG: Solving for T, Initial residual = 0.547374, Final residual = 9.2739e-07, No Iterations 75
DILUPBiCG: Solving for x, Initial residual = 0.573135, Final residual = 8.78534e-07, No Iterations 75
DICPCG: Solving for p_rgh, Initial residual = 1, Final residual = 0.00901403, No Iterations 23
