COEFF_mue
scaling factor for numerical viscosity (UCV)
COEFF_mue corresponds to the parameter C in the definition of the numerical viscosity, see %ind_ETA_sm%. For the use in the numerical scheme, see v-- and vp-.
COEFF_mue = 0.5
Default: COEFF_mue = 1.0
Note: Positive values of COEFF_mue<1.0 should lead to results that are closer to the actual solution. However, this can lead to
numerical instabilities. In this case, COEFF_mue should be enlarged. If required, also values >1.0 can be chosen, e.g. 2 or 4.
