Default region adaption

Hi!

When you patch a region - actually when you adapt a region (something like in fluent vof tutorial) how can you define a more complicated shape (not square, circle or cylinder)?

Thanks

This is where 'combine' and 'mask' come into play in the manage adaption window.

You can combine regions of simpler shape to form more complex shapes, this is similar to what you do in Gambit when uniting volumes. If a register is 'masked', combining registers is equal to a substract operation.

Hi!

Thanks! But the only geometries that you can work with are circle and rectangle...or am I wrong? A simple question...How do you create a triangle for example??? I actually want to simulate splashing water in tank. for initial condition I want to define the surface as a sine/cosine function...

No, I guess that is too complicated to solve with the relatively simple registers. In that case I would define this surface in Gambit and create a special fluid zone underneath it that can be patched individually with the initial conditions.
