We will be offering the following webinars as part of our IGDigital event series:
Thursday, March 11, 2:00 - 3:00 pm CET
Webinar 1: RISTRA - Rapid simulations on graphic cards for structural analysis
Speaker: Dr. Daniel Weber, moderation: Prof. Dr. André Stork
Numerical simulations are an integral part of the product development process, in which stress distributions are calculated by means of selected load cases. If critical stress peaks occur, the geometry must be modified at relevant points. This iterative process of geometric modeling, simulation and analysis of the results usually involves multiple CAx tools. In addition, the process is usually very time-consuming due to the manual conversion effort of the models between the tools and long simulation times. Testing and optimizing various alternative CAD geometries in a short time is therefore difficult.
We would like to present our solutions to you:
- Accelerated calculations by a factor of more than 80 – completed in just seconds, depending on the size of the network.
- Direct visualization of simulation results for the analysis of stress distributions in components, and
- Simple operations for geometry changes on simulation meshes.
Thursday, April 15, 2:00 - 3:00 pm CET
Webinar 2: Intuitive and elegant definition of material gradients on CAD models
Speaker: Thu Huong Luu, moderation: Prof. Dr. André Stork
Providing CAD models with locally varying properties is currently difficult and time-consuming for designers, engineers and 3D printing service providers.
It is common practice to either divide the model into sub-models, to which differing materials are then assigned, or to perform the material assignment based on images (textures) in a preparation step for 3D printing. The former method usually only allows discrete material transitions, while the latter requires the gradation to be generated as a variation of the texture information.
The challenge is to easily and quickly generate continuous material gradients that follow the geometry, as they can be produced with modern multi-material printers. In this webinar, we would like to introduce you to the GraMMaCAD tool for simplified definition of material distribution.
Wednesday, May 12, 2:00 - 3:00 pm CET
Webinar 3: New representation schemes for smooth transitions between design and simulation
Speaker: Dr. Christian Altenhofen, moderation: Prof. Dr. André Stork
We would like to show you a volumetric subdivision that enables the tighter integration of geometric modeling with physically based simulation. We are chiefly interested in representations that can be used for volumetric objects and graded properties, and that are suitable for modeling, simulation and 3D printing – without sacrificing mathematical accuracy and continuity. To this end, we are developing subdivision methods and researching intuitive metaphors for the interactive creation and modification of true volumetric objects.
