Using CAD models for the isogeometric B-Rep analysis (IBRA) offers the possibility for simple and comprehensive integration of CAD and CAE. This feature is also one of the basic ideas of isogeometric analysis. Moreover, this allows to abdicate the extensive and time-consuming conversion of the design model to a analysis model.
The new developed design-through-analysis workflow Analysis in Computer Aided Design (AiCAD) based on the isogeometric B-Rep analysis [Breitenberger et al. 2015] is realized with the library TeDA (Tool to enhance Design by Analysis). Furthermore Isogeometric Analysis is available in the parametric design tool Grasshopper in Rhino with Kiwi!3d.
