I'm trying to discretise the conservative equations using FVM for a 1-D spherical geometry (i.e. spherical symmetry).
After applying the Gaus's theorem I get the following for spatial discretisation of the diffusive terms ![]() I know that for 1-D Cartesian the face area vector is simply ![]() However, what will be the face area vector for a spherical geometry? Surely it can't just be the unit vector. I know that the area element in spherical coordinates is given by ![]() Thanks. |
