The method remains stable with large time steps, while keeping the complexity of an explicit scheme: it does not require the assembly and resolution of large linear systems for the time iterations. The approach is based on a kinetic representation of the system of conservation laws previously investigated by the authors. In this paper, the approach is extended with a subdomain strategy that improves the parallel scaling of the method on computers with distributed memory.", "revisions": [ { "version": "v1", "updated": "2022-12-21T13:30:55.000Z" } ], "analyses": { "subjects": [ "65M60", "65Y05" ], "keywords": [ "large time steps", "conservation laws", "parallel kinetic schemes", "parallel discontinuous galerkin method", "large linear systems" ], "note": { "typesetting": "TeX", "pages": 0, "language": "en", "license": "arXiv", "status": "editable" } } }
