Arbitary Order Lagrange Hexahedron Element Connectivity


The new versions of ParaView(5.5 and above) supports arbitary order lagrange hexahedron elements. The ordering of the points (lagrange points facepoints+interior+corners)associated with the elements hasn’t been provided either in the ParaView reference guide or in VTK file format specification in VTK guide. (For simple hex the ordering of nodes is clockwise from inside the cell for one face and similar for the nodes in the opp face ). How do we figure such ordering or pattern for the Arbitary Order Lagrange Hexahedron ?

@tjcorona or @dcthomp should know.


I haven’t had luck messaging them, anyway I could get any leads on the topic? Anything however small is appreciated

Here is a blog post @tjcorona and @dcthomp wrote that should shed light on the ordering.


The comments under the blogpost actually helped me find the solution, someone spotted a few mistakes in the blogpost as well. Thanks for the solution !
