Does anybody have any idea how to deal with the following error?



I encounter the error when running foam-extend 4.1 in parallel "Some processors detect different empty (2-D) directions. Probably using empty patches on a bad parallel decomposition".



My empty direction is along x-axis. I tried different decomposing methods in decomposeParDict file and the domain is successfully decomposed as expected. , but it keeps giving the same error. The error pops up at the first time step most of the time, sometime after some iterations. By the way, I am using sixDoFRigidBodyDisplacement boundary condition (0/pointDisplacement) and the solver is interDyMFoam.



The case runs well in serial mode.



decomposeParDict:

numberOfSubdomains 2;
method simple;
//method scotch; //same error
//method metis; //same error
simpleCoeffs
{
n ( 1 2 1 );
delta 0.001;
}
