My question is that is it possible to somehow mesh the geometry on picture with hex elements, 2,5D mesh? It s a cut out of a spiral bevel gear. When selecting 2,5D mesh the software won't allow me to mesh the body.
One more thing, can I convert the quadrilateral surface mesh into triangular mesh which basis is the former mesh?
You need to get rid of this sliver face. There are various ways you can do this. I did it by creating extra vertices (using the Add/Remove Vertex tool) on the inner edge, then dragging these onto the equivalent vertices on the outer edge:
