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

d(UDS)/dy=0

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?

Thanks!

R

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