Dear Yves,
I am wondering if this feature can be extended to the geometric
transformations. Actually I am looking for the way to use isoparametric Quad 8
and Hexa 20 serendipity elements. The FEMs "FEM_Q2_INCOMPLETE(P)" are well
defined but I would like to define a convex with a geometric transformation
like "QT_Q2_INCOMPLETE(P)" . In short words how can I define for example Quad
8 or Hexa 20 convex?
Best regards,
Yao Koutsawa
