region with special boundaries

Dear all

How can we define a region with boundaries defined by a function?
(e.g. a cube with sinusoidal wavy walls)
Is it possible?

best,
Fahim

what do you need that region for?

Is it possible?

you'll likely have to do some C++ programming, since
i am not aware of any existing functionality to do that.

yikes!!!

yeah. it is probably best to program a fix that implements
this specific wall model.
