Over the past decades, CAD and CAE scientific communities have been developed independently from each other, by using different basis for the geometric representation. This dual approach leads to a computationally expensive and error-prone model conversion, commonly called finite element mesh generation. However, by designing a CAD model, in fact, one already implicitly creates its corresponding mesh of finite elements. Focusing one this idea, Isogeometric analysis merges modeling and analysis into one, unified NURBS based representation.
The present work deals with the implementation of a basic Multi-patch Isogeometric Analysis in Kratos, using the penalty approach as a domain decomposition method. Furthermore, a GiD plug-in was developed, allowing the direct use of it, as an Isogeometric analysis preprocessor.
