How CAD and FEA can be used for isogeometric analysis?

Currently, it is necessary to convert data between CAD and FEA packages to analyse new designs during development, a difficult task since the two computational geometric approaches are different. Isogeometric analysis employs complex NURBS geometry (the basis of most CAD packages) in the FEA application directly.

Why do CAD models need a command based approach?

The command and GUI-based approaches are typically essential once the design of the CAD model has been completed and is only imported and processed for the analysis model. In that scenario, selecting the according geometries is pretty simplified and fast, even for untrained users.

What is Iga CAD?

It addresses both the direct computation on existing CAD drawings and the geometrical design during the preparation of the numerical models. The developments are presented through the example of the open source Rhino plugin Cocodrilo, which shall bring IGA to a larger community, including research and industrial facilities.

What is the difference between software architecture and interaction with CAD data?

Interaction with the CAD-data presents user interfaces for CAD models to enhance them with the required physics and user information. Software architecture features a suitable software architecture to achieves a full CAD-integrated design considering all peculiarities discussed within the previous sections.
