Default velocity gradient
Posts: n/a
Hi i wanted to know can i use C_U_G(c,t)[0] and C_V_G(c,t)[1] for accessing du_dx and dv_dr (velocity derivatives) in a 2d axisymmetric problem . Does the preceding Macro give me velocity gradient in axial and radial direction or i can use it just in Cartesian coordinates
