Hello,

I've run into a possible bug in OF5.0 for in the solvers buoantSimpleFoam and buoantPimpleFoam.

When running either solver, the solver encounters an error but doesn't return any faults to the command line output.

Can anyone clarify why the solver exits without giving an error?

EDIT: Some more information, if I replace the fvSolutions/fvSchemes with ones that work with simpleFoam the simpleFoam solver runs without issue.

Here is an example of the output I get when running buoyantSimpleFoam:

Create time

Create mesh for time = 0


SIMPLE: convergence criteria
    field p_rgh  tolerance 0.0001
    field U      tolerance 0.0001
    field h      tolerance 0.0001
    field "(k|epsilon|omega)"    tolerance 0.001

However, when I try running in parallel I get:

Create time

Create mesh for time = 0

    field p_rgh  tolerance 0.0001
    field U      tolerance 0.0001
    field h      tolerance 0.0001
    field "(k|epsilon|omega)"    tolerance 0.001

-------------------------------------------------------
Primary job  terminated normally, but 1 process returned
a non-zero exit code.. Per user-direction, the job has been aborted.
-------------------------------------------------------
--------------------------------------------------------------------------
mpirun detected that one or more processes exited with non-zero status, thus causing
the job to be terminated. The first process to do so was:

  Process name: [[12539,1],0]
  Exit code:    142
--------------------------------------------------------------------------

I've noticed that if I delete 0/T or 0/p I get an error.

However, if I delete 0/U the solver again returns:

Create time

Create mesh for time = 0
