hi foamers.
i use pimpleDyMFoam and RBF Function. when running in parallel following error appear.

Code:
Create time

Create dynamic mesh for time = 0

Selecting dynamicFvMesh dynamicMotionSolverFvMesh
Selecting motion solver: RBFMotionSolver
Radial Basis Function interpolation: Selecting RBF function: IMQB
Total points on moving boundaries: 0
Total points on static boundaries: 3925
Selected 0 control points on moving boundaries
Number of internal points: 34922
Reading field p

Reading field U

Reading/calculating face flux field phi

Selecting incompressible transport model Newtonian
Selecting turbulence model type laminar
Reading field rAU if present


Starting time loop

Courant Number mean: 0 max: 0 velocity magnitude: 0
deltaT = 0.012
Time = 0.012

MPI_ABORT was invoked on rank 0 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 0 with PID 15707 on
node saeid-Inspiron-N4010 exiting without calling "finalize". This may
have caused other processes in the application to be
terminated by signals sent by mpirun (as reported here).

Code:

Send a message via MSN to owayz
Your velocity is 0. May be this is causing the problem?
Or may there is some problem with solver you are using in the fvSolution dictionary.
