Introducing Franck Eric Njilie Adamou, who in his role of Safety Development Director for Altair’s Simulation & Design Development, has played the pivotal role of preparing the OpenRadioss Community Dummies for their reemergence into the real world of explicit dynamics. Frank Njilie is a seasoned expert in the development and validation of safety simulation models in the automotive industry.

For everyone working in R&D, safety, and biomechanics, free, open-source FEA dummies for OpenRadioss are now available. Created in the past, this family proved themselves to be sufficiently accurate for research applications and academia. Let’s work together to bring them out of retirement and get them back to work! Click here to meet the family.

When you visit the OpenRadioss download page, you’ll notice we’ve instigated a quick poll to get a better idea of the background and expected applications of OpenRadioss envisaged by our Community. To help us shape the future of OpenRadioss, please spend 5 minutes to complete the poll. Thank you!

A Fully Open-Source Workflow for Impact Simulations:

In-person event | Saturday, March 29th | 9am | Altair Cologne, Germany

Aleksander Sadowski, from Alsado, will present a fully open-source workflow for impact simulations using the example of a drop-off simulation of Alsado’s ready-to-3D-print Mars Rover mascot, as part of the DLR "Tag der Raumfahrt 2025” study.

Bring your laptop with the workflow software preinstalled, to gain hands-on experience of the workflow. Seats are limited at this in-person only event, it’s first come - first served.
