Abstract

Trimmed CAD models are the most popular geometry representation in engineering design, but their direct application to an isogeometric analysis can lead to ill‐conditioned system matrices. An approach is presented that effectively resolves this issue by combining so‐called extended B‐splines with a local refinement procedure. [ABSTRACT FROM AUTHOR]
