Implicit solvers for unstructured meshes

WitrynaImplicit methods were developed and tested for unstructured mesh computations. The approximate system which arises from the Newton linearization of the nonlinear … Witrynaor matrix-free implicit methods can be employed, but for many real-world problems and meshes full Jacobian matrices are required for the solvers to be e cient. Here, nodal-based Galerkin methods have a fundamental disadvantage in that they connect all unknowns inside an element, as well as all neighboring face nodes, even for rst-order …
