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 ... WebIn FEniCS, these kind of problems are handled by defining subdomains inside the domain. The subdomains may represent the various materials. ... The family of discontinuous Galerkin methods, in FEniCS denoted by 'DG', is suitable for this purpose. Since we want functions that are piecewise constant, the value of the degree parameter is zero: WebElement families¶. UFL predefines a set of names of known element families. When defining a finite element below, the argument family is a string and its possible values include "Lagrange" or "CG", representing standard scalar Lagrange finite elements (continuous piecewise polynomial functions); "Discontinuous Lagrange" or "DG", representing scalar … allrecipes stuffed bell peppers
