You are right. It was indeed a problem of some duplicate elements.
Thanks. Closing the bug as invalid.

I agree with Gianluca.
check the original mesh with transparency to see if elements are duplicated (they appear darker). maybe the problem occurs before the extrusion

That s strange. Can it be that some hexahedrons were duplicated in the volume mesh?

The Mesh.getBorderMesh method may produce incorrect results, as is shown in the attached image. The left viewport shows a Mesh of a stent, drawn as is ('hex8'). In the right viewport we draw the result of Mesh.getBoderMesh(), i.e. the free border faces, which is a 'quad4' type Mesh. The faces are drawn with black front color and green back color. Clearly some struts are missing.
