WebMay 14, 2024 · Questions about the finite element method software FEniCS and its subpackages (Dolfin, UFL, FFC). ... Penalization parameter for DG with jump penalization. I adapted this FEniCS code for my problem and I'm wondering if there is any good resource about how to choose the penalty parameter $\alpha$? Best case would be, if I can define … WebMixed formulation for the Poisson equation. We’re considering the Poisson equation ∇ 2 u = − f using a mixed formulation on two coupled fields. We start by introducing the negative flux σ = ∇ u as an auxiliary vector-valued variable. This leaves us with the PDE on a unit square Ω = [ 0, 1] × [ 0, 1] with boundary Γ. for some known ...

The subdomains may represent the various materials. ... The family of discontinuous Galerkin methods, in FEniCS denoted by 'DG', is suitable for this purpose.
