Hi,

Who knows how to written the HDG(hybridization of LDG) with variable (L,u,uhat,p) with NGsolve?

How to define the variable ‘L’ and how to eliminate the ‘(L,u,p)’ with uhat locally?

Thanks.

Hi Yihui,

the tutorial on HDG (link) might be a good starting point.

Hi Michael,

The link you recommend is hybridization of DG, the variable ‘L’ is not introduced in the scheme.

I want to give the “fes = FESpace([W,V,M,Q])”, where W is tensor L2 space, V is VectorL2 pace “V = VectorL2(mesh, order=k)”, M and Q are known. But I don’t know how to give this FESpace.

Do you have any idea about this?

Thanks
