Dear all, I need a function to insert cells in a tetrahedral mesh via incident vertices. I searched the documentation and I found out that such a function is available for hexahedral meshes. Seems that for tetrahedral meshes the only way to insert cells is via its halffaces.

Specifically, I am using CGAL to generate a 3D Delaunay triangulation, and I want to save the result as a OVM mesh. I can easily access the vertices of the cells in the Delaunay triangulation, and that's why I would like to add cells to the OVM mesh via incident vertices.

I used the vertices of the cells in the Delaunay triangulation to create the half-faces and then I used these half-faces to create the cells. Just as in this example: http://www.openvolumemesh.org/svnrepo/OpenVolumeMesh/trunk/examples/simple_m...

However this approach generated many duplicated faces, since I create twice the faces shared by two cells.

Does anyone have any idea to help?

Thx in advance!
