To avoid the use of a complex\nunstructured mesh that perfectly fits the geometry of the boundary\na penalization technique can be used. We shall c ompare a direct\napplication of the MsFEM on the perforated domain and its \ncombination with the penalization approach. The disadvantage of the\ndir ect method (apart from the use of complex meshes) consists in\nthe necessi ty to develop new oversampling methods which turn out to\nbe less efficien t than the classical oversempling technique applied\nto the penalized prob lem. We shall also present new variants of\nMsFEM inspired by the non conf orming finite elements à la\nCrouzeix-Raviart. We present numerical result s for academic test\ncases inspired by homogeneization theory and for the problem of\npollution spreading in urban areas. In the last case\, the goa l of\nthe MsFEM is to be able to perform a fast real time computation on\n a genuine urban area. Other possible applications include analysis\nof per forated or cracked materials\, air flow inside a cockpit\, and\nso on.\n DTSTART:20101129T210000Z DTEND:20101129T220000Z LOCATION:Burnside Hall\, CA\, QC\, Montreal\, H3A 0B9\, 805 rue Sherbrooke Ouest SUMMARY:Multiscale finite element method for perforated domains URL:/channels/event/multiscale-finite-element-method-p erforated-domains-168424 END:VEVENT END:VCALENDAR
