ANurbs is a geometry kernel developed for Isogeometric Brep Analysis (IBRA).

Some of the features:

  • Evaluation of planar and spatial B-Spline and NURBS curves and surfaces
  • Data structures for storing and evaluating Brep-Modells
  • Computation of shape functions required for IGA based Finite Elements
  • A packed Hilbert R-Tree for fast spatial queries
  • Computation of integration points required for trimmed Multipatches
  • Interfaces to Rhino
  • High-Performant C++ Kernel
  • Easy to use due an extenvie Python interface

ANurbs has been used successfully in research and for industrial projects.
