UDS Neumann Boundary Condition
Hi All,

I am trying to set a Neumann Boundary condition in the outlet of a long tube for the concentration gradient of an UDS. This is, I want to implement


In the outlet (or cells adjacent to the outlet boundary). I imagine I should use DEFINE_PROFILE and C_UDSI_G. Has anyone done this in the past either with UDS, pressure, temperature, or anything else?

Look really carefully at the GUI panel and you will find where to set the b.c. for user-defined scalar(s).
