Hi all,

Am having some trouble with UDF. Is it possible to modify the UDS diffusivity face values directly using one of the UDF Define macros, i.e. similar to DEFINE_DIFFUSIVITY but for cell face values, and let Fluent calculate the fluxes using that?

This is because I need to create a "discontinuity" for a UDS at a VOF interface, and treat it using Henry's Law.

Thanks for the inputs.

Regards,
Kelvin
