buoyantSimpleFoam abort error
 

Good Evening Everybody,

I am trying to simulate the flow over a hot board to investigate the boundary layer of velocity and temperature. I have already done a simulation with rhoSimpleFoam. Now I want to start a simultion with buoyantSimpleFoam. I´ve made the setup and OpenFoam told me to initialize with potentialFoam. I´ve initialized with my rhoSimpleFoam solution.

Now the simulation starts but then it aborts after few iterations giving me this strange error massage:

I don´t have any clue to interpret this message! What could it mean? Why is my solver aborting?

thanks

try this in your fvSolution for p, pFinal or p_rgh

{
solver PCG;
preconditioner DIC;
tolerance 1e-10;
relTol 0;
}
maybe cure your problem

HI Nima,

thanks for the hint. But it just makes my solver slower and its still aborting at the same step.
As one can see the residuals are exploding.

I´ve got it running but in the end I don´t know what exactly was the important change. Therefore I am uploading the whole case as example and inspiration for everybody who is struggling with buoyantSimpleFoam.
