Normalized turbulence viscosity i.e. viscosity scaled to current level i.e. visc/dtL Size: nSize (nFluids+nGhosts+nHalos) Used gradData to compute viscosity for nFluids and nGhosts. This viscosity is interpolated and scaled for setting nonEq term interpolation routines. The source element of interpolation might be halo so they are communicated.

Simple scaling assumping norm of strainrate tensor |S| in different level is small: Schneider, A. (2015). A Consistent Large Eddy Approach for Lattice Boltzmann Methods and its Application to Complex Flows. Technical University Kaiserslautern. v_c = 4 v_f. Scaled visc: v^s = v/dt. => v^s_c dtL_c = 4 v^s_f dtL_f => v^s_c = 2 v^s_f
