Diffusive flux

Please login with a confirmed email address before reporting spam

Dear all,

I am running some simulations taking into account the diffusive flux across a curved interface using (tds.dflux_cr * nr + tds.dflux_cz * nz). When postprocessing the results, I've noticed that the integral of (tds.dflux_cr * nr + tds.dflux_cz * nz) and tds.ndflux_c at that interface are different. Interestingly, when calculating the integral of tds.ndflux_c, I've got the expected behavior, while the integral of (tds.dflux_cr * nr + tds.dflux_cz * nz) deviates from what I expect. I've then tried to solve the problem specifying tds.ndflux_c for the calculation of the normal diffusive flux across the interface, but the solver fails. Any tips on this behavior?

Best regards, NP

Hi Natan,

For the sake of other users of this Discussion Forum who may some day have the same question, I encourage you to expand on what the problem was.
