Query: Advances in the Treatment of Trimmed CAD Models due to Isogeometric
  Analysis   Trimming is a core technique in geometric modeling. Unfortunately, the
resulting objects do not take the requirements of numerical simulations into
account and yield various problems. This paper outlines principal issues of
trimmed models and highlights different analysis-suitable strategies to address
them. It is discussed that these concepts not only provide important
computational tools for isogeometric analysis, but can also improve the
treatment of trimmed models in a design context.
