6 U-splines
U-splines are a novel spline technology developed by Coreform which seeks to alleviate, if not eliminate, many longstanding limitations in prevailing spline representations, providing a smooth spline meshing technology for industrial-scale FEA applications.
In particular, U-splines can be seen as a generalization of the key innovations underlying both analysis-suitable T-splines (ASTS) and Bézier extraction. Bézier extraction is a method for providing a local Bernstein representation of a non-local smooth spline function, and is used widely in isogeometric analysis (IGA).
With this release, U-splines are now implemented in Coreform Cubit™, making it the world’s first general-purpose isogemetric analysis mesh-preprocessor.
