Hello Nek Users,
I have a periodic fluid domain with heat flux BCs at my walls. To prevent
my temperatures from increasing indefinitely, I am prescribing a sink
within userq using qvol which is equal to "user_flux * wall_surface_area /
fluid_volume".
This works in theory. The issue is that due to round-off errors, my
temperatures still increases (although extremely slowly).
I would like my average temperature be the same regardless of run time.
What would be the most efficient method to balance the temperature in my
domain?
Best,
Jon
