Hi,

I am trying to run a case using MRFSimpleFoam with mixingPlane.
OS : Ubuntu 18.04 on WSL
Foam-extend 4.1

No problem in Serial but when I run the case in parallel, the simulation crash after one step :

Create time

Create mesh for time = 0

Initializing the mixingPlane interpolator between master/shadow patches: AMI1_1/AMI2_1

SIMPLE: no convergence criteria found. Calculations will run for 2000 steps.

Reading field p

Reading field U

Reading/calculating face flux field phi

Selecting incompressible transport model Newtonian
Selecting RAS turbulence model laminar
Creating MRF for cell zone rotating. rpm = 1000

Starting time loop

Creating ggi check function object
Creating mixingPlane check functionObject
Time = 1

Do you have any idea regarding what may happen ?

Thank you.
