Time dependent BC as function of coordinates

tehache · August 2, 2005, 13:46

Hi everybody,

I spent 2 days now trying to figure out how to specify a (temperature) boundary condition as function of coordinate and time.

Any hints ?

Thank you very much !

Have a look at the oscillatingFixedValue stuff and use that as a start - inside the evaluate fuction you can make the patch values a function of whatever you like. This will, of course, give you a new (your own!) boundary condition, which deserves a new name.

I think there's enough details on the b.c. in the forum so there's no point going through it again.

Enjoy,

Hrv
