mus_turbVisc_Smagorinsky_fromGradU3D Subroutine

public subroutine mus_turbVisc_Smagorinsky_fromGradU3D(turbVisc, turbConfig, gradData, auxField, velPos, nSolve, nAuxScalars, dxL, dtL, Grad)

Calculate eddy viscosity with smagorinsky model for compressible model using gradient of velocity The formula is taken from nu_t = C_k delta sqrt(k_sgs) k_sgs = ((-b+sqrt(b^2+4ac))/2a)^2 a = C_e/delta, b=2/3 tr(dev(Strain)), c = 2 C_k delta (dev(Strain):Strain)
