When rendering higher-order elements, does paraview try to tesselate/triangulate the surface using linear elements? I’m trying to use a 15 node tet, and I see a divot in the surface that is reflected in th surface normals

 ![exo_tet_nodes_normals](https://discourse.paraview.org/uploads/default/original/2X/5/5665afae57640fb17b22e3f3053920c46a992b8c.png). This is an image from an exodus file but I see the same thing if I write it out in VTK format. I’m using someone elses code and I’m not convinced he has the node ordering correct but I’ve tried several different orderings and I see the same thing. Has this behaviour been seen with Paraview before for higher-order elements

Thanks
