Variable omega in MRT dynamics with parallel computation

Hello there.
I have some question about variable omega.
I’m simulating about two phase case and I set the omega differently according to density and simulation time step.

However, there are difference between single core simulation and multi core (parallel) simulation.
I doubt about setOmega() function at envelope node of multiblock.

Is there anyone help me and let me know about how to use variable omega for parallel simulation?
