WebJan 1, 2024 · FEniCS provides an interface to state-of-the-art linear solvers and preconditioners from freely available third-party libraries, e.g. PETSc, HYPRE, and Eigen. This is an advantage not found in many other open source projects, which depend on their own solver packages. WebFEniCS is a great solver for FEM, but for example acoustic problems, or heat conduction problem without internal sources can be solved in more efficient manner by BEM. The LBM is great for...
WebJan 28, 2024 · FEniCS with the gmres solver is quite a lot faster than Elmer with the BiCGStabl solver, about 3.7 times faster. However, it is not as accurate. The error plots show higher magnitude errors, especially towards the termination of the domain. Phase errors are somewhat comparable and very low. Web[ [ [ FEniCS can be used in alternative ways for solving a nonlinear PDE problem. We shall in the following subsections go through four solution strategies: a simple Picard-type …
