Dear Robert,
I do not know which is the geometry you want to define, so I cannot provide
you a solution, but I can give you some hints.
1) plane will define half-space. This mean that an orientation is to be
defined. We chose the following strategy: the prescribed normal is the
*external* normal. Then the distance from the origine is relative, so any
combination can be achieved. [I joined an example]
2) You prescibed box dimensions which correspond exactly to your planes
positions. The underlying mesh generation algorithm relies on marching cube
like techniques which may be confused when no security is given: enlarge your
box where it intersects with the half-space.
3) The best way to get any idea of your scene is to visualize the domain as
shown in the provided example.
Stephane.
