Dear Damien,
You should rather directly write this instruction:
self space interface eightconnexe
Would you like to change programmatically the boundary conditions,
you could write:
self space interface closed or self space interface torroidal
Have a look at the methods in the "actions topologie reguliere" of
the VueInterface class. For the next Cormas version (that should be
released in Feb 2002), the programming of the spatial grid has been
cleaned-up, and a single generic method implemented at the level of
the spaceModel will be available, so that from any #init method of
your model, it will be possible to change directly any topological properties.
