Hi Guo,

The descriptor that you are using stores omega in an external field. You may see it in file src/dynamics/dynOmegaLatticeDescriptors.h, where DynOmegaD2Q9Descriptor is defined.

I would suggest using:

SuperLatticeField3D<T,DESCRIPTOR,OMEGA> omegaLB (sLattice);
vtkWriter.addFunctor(omegaLB);

This would print the relaxation frequency (omega) in lattice units to the VTK file. Is this what you are looking for?

Cheers,
Aurelio
