paraDiGMS
Geometry modelling and computer-aided design (CAD) play an important role in many areas of research at the German Aerospace Center (Deutsches Zentrum für Luft- und Raumfahrt; DLR), for example in the design of components or digital twins in aerospace. As different as the applications are, the challenges in geometry modelling are often similar.
The paraDiGMS project aims to combine the geometric modelling expertise of 13 DLR institutes. The aim is to create a comprehensive open source tool landscape that enables the joint, agile and requirements-driven development of geometry modelling methods. The methods will be tested and further optimised during the development process using real applications from the participating institutes.
A major contribution by the Institute for Software Technology is the "grunk" software developed specifically for the platform. It is designed to allow all DLR researchers to use various geometry tools in a central location.
The paraDiGMS tool landscape aims to close four competence gaps in geometry modelling:
- Provide a freely available, platform independent CAD modelling core.
- A generic parametric engine will be provided. It is used to control the CAD modelling core, but also provides a generic exchange format for design process interoperability. The parametric engine has a plug-in system and is modularly extensible.
- The CAD modelling kernel is algorithmically differentiated and therefore particularly suitable for gradient-based design optimisation.
- The paraDiGMS tool environment can be seamlessly integrated into high-precision simulations and analyses, and provides networking and simulation tools with access to real geometry.
