Inconsistency in Boundary Flux Units for 2D-Axisymmetric Mass Flux

Please login with a confirmed email address before reporting spam

Hi all,

I'm trying to express a mass flux term through a radial boundary, in a 2D-Axisymmetric system.

However, COMSOL only accepts a flux of (mol/m s), which is illogical, considering that flux terms are in (mol/m^2 s). Moreover, the help file itself suggests that the units are supposed to be in (mol/m^2 s). Attached is a screenshot.

Can anybody assist with pointing out whether there are any quirks with the 2D-Axisymmetric geometry that leads to such an inconsistent unit?

I also had this problem, but it was fixed in the update of Comsol 4.4; it was a bug.
