Arbitary Higher Order Lagrange hexahedron elements and data

Rohit Vuppala

Hi

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 ?
