Runtime variable boundary condition

ale_sandro · May 9, 2011, 07:52

Hi everybody,

I would like to write this boundary condition: grad(x) = f(time,...)
in which the function is some kind of non stationary function.
I want f(t) to change each iteration (and consequently x gradient).

Does anyone know if a similar patch already exist (maybe for radiating cases)? If positive, where can i find it?

Thanks!

Hi ale_sandro,

maybe the groovyBC fits your needs:
