Hello, load “element_p1dc1” is applicable to 1D problem, while p2dc is not applicable to 1D problem. What are the commands for high-order interpolation, quadratic interpolation and cubic interpolation of 1D discontinuous finite element?

This is no problem

see

load "msh3"
meshL Th=Sline(10); 
fespace Wh(Th,P2dcL);
