Advances in the Treatment of Trimmed CAD Models due to Isogeometric Analysis
For researchers in isogeometric analysis and geometric modeling, this paper provides a conceptual overview of strategies to handle trimmed models, but it is incremental as it reviews existing approaches without presenting new results or quantitative improvements.
This paper outlines principal issues of trimmed CAD models in isogeometric analysis and highlights analysis-suitable strategies to address them, showing that these concepts can also improve treatment in a design context.
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.
