lost.identity is on a distinguished road
Hi,

Just a quick question, in FVM the divergence theorem is applied for the volume intergrals to convert them to spherical integrals. For the case of a spherical geometry what would the divergence be?

\int_t\int_V \nabla\cdot\boldsymbol{F}\,dVdt = \int_t\int_S\boldsymbol{F}\cdot\boldsymbol{n}\,dSdt

Also, since divergence theorem is not applied for 1-D, what whould this be for a spherically symmetric case?
