WebBefore turning to the FEniCS implementation, we discuss how the data of the problem is expressed in FEniCS. In this case, the only data we need to supply is the mesh (which implies the domain), and right-hand side function f: !R. There are numerous ways to de ne a mesh in FEniCS. It may be constructed externally to FEniCS by various di erent ... WebOct 22, 2024 · In FEniCS, we can make use of this by creating the mesh function corresponding to the mesh entities. In this case we are marking the boundary condition in curve mesh entity and the material subdomain is marked in the surface mesh entity. So you have to create two mesh function corresponding to curve and surface mesh entity.
