Dear foamers,

I have a question about using decomposeParDict for Eulerian-Lagrangian solvers. I am trying to assign more cores to the location of mesh where particles are concentrated. The following hint in decomposeParDict is adressing the solution to this issue:

Use the volScalarField named here as a weight for each cell in the
// decomposition. For example, use a particle population field to decompose
// for a balanced number of particles in a lagrangian simulation.
// weightField dsmcRhoNMean;

I used alpha.water as a volScalarField here, but it did not work. Is there anybody with experience in using such a capability of decomposition in OpenFOAM?

I have same doubts, can decomposing be weighted by rhoEffLagrangian field??
