Greetings all

I am working with a modified pisoFoam solver and I have basically a problem, when i run the solver parallel.

I can run the simulation serial and parallel. However, the parallel simulation is crashing after few time steps.
I am using cycling BC for the (inlet and outlet) and for (front and back)
Here is the output of the parallel case:

Code:

I am using OF.3.0.1 and ubuntu 16.04

I appreciate any help
Thanks in advance.

Did you try to use the 'preservePatches' option while decomposing the mesh?

Hello everyone,

I am working with a modified BouyantBossinesqpisoFoam solver in extended-foam-3.1, and I have basically a problem when I run the solver parallel. My simulation geometry is a horizontal rotating pipe with filled suspension and no inflow and outflow.


I can run the simulation serial and parallel. However, the parallel simulation is crashing after 3-time steps.

I am using buoyantPressure for pressure at the inlet, outlet and surface, and at out and following conventional BC of No slip Boundary condition at the inlet, outlet and surface.


This type of error is shown in my terminal.
Code:
