Assuming only the jumps of the pressure are present along the interface, we develop a new numerical scheme for such a problem. By constructing an approximate singular function and removing it, we can apply a standard finite element method to solve it. A main advantage of our scheme is that one can use a uniform grid. We observe optimal $O(h)$ order for the pressure and $O(h^2)$ order for the velocity.", "revisions": [ { "version": "v1", "updated": "2009-11-25T07:05:12.000Z" } ], "analyses": { "subjects": [ "65Z05", "76D07" ], "keywords": [ "extraction method", "standard finite element method", "approximate singular function", "incompressible stokes flow", "singular forces" ], "note": { "typesetting": "TeX", "pages": 0, "language": "en", "license": "arXiv", "status": "editable", "adsabs": "2009arXiv0911.4769C" } } }
