 July 25, 2002, 10:13 Non manifold intersection zone #1 Dimitri Guest   Posts: n/a Hello, I'm working on the simulation of a car-park. I need to simulate the presence of a moving car and then, I'm using a sliding mesh. To improve the simulation, I've defined some boundary conditions to periodic but now, I'm obtaining the error message : "non manifold-intersection zone 30". Is anybody knowing what's the meaning of this ? Thanks. Dimitri

So you have set exactly the same number of cells on the faces in the y direction ?? DC

I'm simulating a movement in the x direction and the periodics conditions are in the plane y-z. I've meshing it by gambit and, to put the periodic bc, I had to link these two faces. The non-manifold intersection zone is an interface between the sliding mesh and an other fluid zone and then is in the plane x-y. Dimitri
