It depends somewhat on the tri-surface mesh you are using.  The non-manifold edges would indicate there is definitely a problem and the resulting geometry is invalid.  I would look at the input surface to see if there are any intersecting element faces or face normals pointing the wrong direction.  Also, I attached an network that I put together that ads a HexVolSheet of a tri-surf cylinder to a "LatVol."

I am interested in seeing whether the InsertHexVolSheetAlongSurface function could be used for our application.  I have tried to recreate the simple example shown in the literature: I have created a hex mesh using CreateLatVol and then have created a cylindrical tri surface mesh using our own software.  Both of these can be viewed successfully in SCIRun.  When I try to run the InsertHexVolSheetAlongSurface function there are several warnings and errors reporting non-manifold edges and problems adding new layers of hexes.  The final number of hexes on each side is reasonable but the number of nodes along the shared boundary seems far too small.  When the output is viewed there are just a few, seemingly random, points displayed.
Can I expect this function to work with this input?  Do you have any examples which I could run to see how it works?
