An immersed-isogeometric model: application to linear elasticity and implementation with THBox-splinesGiannelli, Carlotta, 1980- ...Študiramo uporabo potopljenega roba v izogeometrični analizi pri obravnavi fleksibilnih domen, tako da primerno vključimo operacije rezanja in geometrijske preslikave. Obravnavani potopljen ... izogeometričen model je postavljen v kontekst samodejne adaptive sheme za reševanje problemov linearne elastičnosti. Iz formulacije dobimo simetričen sistem linearnih enačb, hkrati uporabniku ni potrebno nastavljati nobenih bistvenih kazenskih ali stabilizacijskih parametrov. Adaptivnost dosežemo z uporabo hierarhično gnezdenih prostorov zlepkov. Natančneje, osredotočimo se na prisekane hierarhične škatlaste zlepke (TH škatlasti zlepki), definirane na regularnih triangulacijah. Preko več numeričnih zgledov demonstriramo optimalni red konvergence za predstavljeno adaptivno shemo.Source: Journal of computational and applied mathematics. - ISSN 0377-0427 (Vol. 349, Mar. 2019, str. 410-423)Type of material - article, component part ; adult, seriousPublish date - 2019Language - englishCOBISS.SI-ID - 18786649
