If the flux consist of both convective(a) and diffusive(b) flux, then:

(a) The udf deffine_uds_flux only deffines the convective flux through all faces, even boundary faces.

(b) The diffusive flux is calculated by Fluent, the udf deffine_diffusivity is used to deffine the diffusivity coefficient.

At the boundaries: When you use flux as a boundary condition, is it then convective(a) or convective and diffusive(a+b) flux that you deffine?
