Rhino 3d To Abaqus: A T-Spline Based Isogeometric Analysis Software Framework

This chapter presents a novel software framework for T-spline based isogeometric analysis (IGA), interfacing between computer aided design (CAD) and finite element analysis environment for "design-through-analysis" concept. The framework is built on Rhinoceros 3D (Rhino) and SIMULIA Abaqus (Abaqus). This framework has three primary steps: creating CAD surface in Rhino with T-spline Plugin, converting surface T-spline representations into volumetric T-spline, and performing analysis with T-spline models in Abaqus through its user element subroutine. Both 2D and 3D examples are provided in the end to demonstrate our T-spline based IGA software framework.
