getGradRhoU3_3D Function

private pure function getGradRhoU3_3D(auxField, gradData, velPos, densPos, nAuxScalars, nDims, nSolve, elemOffset) result(gradRhoU3)

This function computes gradient of rho * velocity^3 from gradient, density and veleocity data. Just derivatives u_x, v_y and w_z. Gradient is computed using central difference. if an element has an boundary then neighbor refers to current element then forward difference is used.
