1D discontinuous Galerkin FEM code

General Discussion
#1

Hello, teacher, Can freefem++ write 1D discontinuous Galerkin FEM code?

#2

yes you can !
except periodic boundary condition (no jump, mean, on periodic boundary ).

#3

Hello, in fact, if there is a jump on periodic boundary, can freefem++ not implement the 1D discontinuous Galerkin FEM code?

#4

Yes the jump ans mena function is implémentée in version 4.11,

I have try it sèmes ok.

Hello, as shown in the figure, this is a 1D discontinuous finite element problem. If I want to realize the above boundary term (the second term in the last line)in FreeFem++, how can I achieve it? thank you
