When checking my 2D grid under Fluent 5, I get the following message : "Warning ! Non positive face area exists."

My minimum face area equals zero.

The grid seems ok, since no nodes are redundant. I really can't understand why a face area is detcted.

Any idea ? Thanx in advance.

Fluent France should be able to help you with this. You may need to send the grid file to them.

You probably have a collapsed cell somewhere in your grid. I suggest that you bring it back to the pre-processor and check the quality of it.

Hi, I think you should used the Tgrid to check the mesh,it will help you check you mesh. wang haiggang
