interDyMFoam fails in parallel
Hello all,

first of all the outputs from the debug-version:

Create time

Create mesh for time = 0


Selecting incompressible transport model Newtonian
Selecting RAS turbulence model laminar
time step continuity errors : sum local = 0, global = 0, cumulative = 0
2 additional processes aborted (not shown)

FOAM parallel run aborting

Now some details:

- the calculation fails at the point when the pressure-equation is to be solved

- boundary conditions for pressure:
all boundaries have a zeroGradient condition for the pressure
so a reference cell and reference value for pd are defined

-the calculation with interDyMFaom fails if:
- the above boundary condition for the pressure is applied and the computation is parallel

- in the following cases the calculation runs without problems:
-serial calculation with interDyMFoam
-parallel calculation (interDyMFoam) but with a fixedValue b.c. for the pressure (splitting the domain in such a way that every processor domain contains a part of that patch)
-when using interFoam (interFoam runs in parallel even with zeroGradient on all boundaries)

From the output of the debug version i see that there is an index out of bounds.

Does anybody know or have an idea why this problem occurs?

Thank You

Looks like a bug. Can you set up a testcase and post it on the OpenFOAM-bugs forum?

Thanks, Mattijs

Hi Mattijs,

on monday there will be an uploaded testcase.

Thank you
