hello everyone!
I’m a beginner of OpenFOAM and I’m using OpenFOAM-extend-3.2.
Recently i'am using the RBFmotionFunction to solver a case about flapping wing, It works perfectly when it runs in serial.
And as we known, the RBFmotionfunction requires that every processor must contain a part of the moving patch, my computational domain is a circle so i use a manual decomposePar justlike a PizzaCut. and when it is divided into 4 parts, it can also work. but when the number of processors increases, the problem "face 0 area does not match neighbour by xxx%" occurs. And after reading all threads about this, i really still have no clue. Is there someone can help me? Thhhhhhhhhhanks a lot!

MPI_ABORT was invoked on rank 4 in communicator MPI_COMM_WORLD
with errorcode 1.

NOTE: invoking MPI_ABORT causes Open MPI to kill all MPI processes.
You may or may not see output from other processes, depending on
exactly when Open MPI kills them.
--------------------------------------------------------------------------
--------------------------------------------------------------------------
mpirun has exited due to process rank 4 with PID 8111 on
node node29 exiting without calling "finalize". This may
have caused other processes in the application to be
terminated by signals sent by mpirun (as reported here).
