[ODE] placing static (non-moving) geoms

[Matthews, Steve USA]

Hi all

  Can anyone please tell me how to place a geom (at a location other than the origin) that is non-moveable, or for which collision works, but physics doesn't?  I want to place the walls of a building, and I don't want them to be moveable, but I want collision detection to work against them.  Guess I could use another product, but I thought maybe there was a way to do this in ODE.

Thanks
