WebBack to FEniCS: As the above tried to illustrate, mesh objects are described by their codimension; nevertheless, MeshFunction takes the actual (geometric) dimension, which by simple arithmetic is "n minus codimension". To write this in a dimension-independent way, you can make use of the function `mesh.topology().dim() So for example, to mark WebApr 29, 2024 · domain, a FENICS code which creates a region starting with a circle, and then "subtracting" a rectangle and smaller circle. dpg_bvp, a FENICS code which uses the Discontinuous Petrov Galerkin (DPG) method to solve a boundary value problem over an interval, by Jay Gopalakrishnan.
