How to assign Neumann boundary conditions in finite elements?

WebFEniCS imposes these constraints this after assembling the stiffness matrix and load vector, by modifying entries associated to boundary DOFs. For this, we need to specify to FEniCS which DOFs are to be constrained (in this case all the DOFs on the boundary), and what they are to be constrained to (namely g). This is accomplished by invoking ...

WebIn FEniCS, these kind of problems are handled by defining subdomains inside the domain. The subdomains may represent the various materials. We can thereafter define material properties through functions, known in FEniCS as mesh functions , that are piecewise constant in each subdomain. A simple example with two materials (subdomains) in 2D …
