TīmeklisFEniCS is a user-friendly tool for solving partial differential equations (PDEs). The goal of this tutorial is to get you started with FEniCS through a series of simple examples that demonstrate how to define the PDE problem in terms of a variational problem, how to define simple domains, how to deal with Dirichlet, Neumann, and Robin conditions, TīmeklisThis class implements Krylov methods for linear systems of the form Ax = b. It is a wrapper for the Krylov solvers of PETSc. Overloaded versions. …
