The presented technology further develops the hybrid collocation concept to accommodate both numerical methods within a single framework, providing a systematic technique for selecting the method to be used. We perform several numerical tests to demonstrate that the methodology guarantees the same convergence rates obtained using the standard isogeometric collocation method.en0045-78252023Finite cell methodHybrid isogeometric collocationImmersed methodIsogeometric analysisTrimmed surfaceJournal Article10.1016/j.cma.2022.115856Other
