Hi all,
Does anybody know how to determine the total flux of a scalar (for example mass fraction of a species) at a certain intersection in a domain? From what I have read it is the sum of the diffusive scalar flux and the convective flux, I however struggle to calculate these. The software that I am using is ConvergeCFD

Hi Velkon,
Yes you can determine the total flux by separating the domain into multiple regions using a flow-through interface, and turning on the mass flux output for each species in the output files > inter-region flow rate output.
If you are looking for a specific scalar flux, you can calculate a particular location using the 3D output files and by selecting respective post variables.
Hope that helped. Let me know if you need more clarity on it.

convection, diffusion, flux, mass fraction (y)
