- 1Interactive 3D Enigma machine simulator goes liveโShow HN: A working 3D model of an Enigma machine
A new website offering a fully working 3D model of the Enigma machine is drawing attention online. Users can explore and operate the famous German WWII cipher device virtually, simulating its rotors and encryption mechanics in the browser. Commenters are praising the project as an impressive blend of history, engineering and interactive web technology, with hundreds engaging shortly after its release.
- 2Siemens Shuts Down Open-Source Radioss Crash Simulation ProjectโSiemens Slams The Door Shut On Promising Open-Source Radioss Project
Siemens is ending Radioss as an open-source project, closing the door on the crash-simulation code that had been developed in the open. The move follows Siemens' earlier acquisition of the software, and observers of the engineering-software world are criticizing the decision to pull back a tool with an active community around it.
- 3Game Design Graduate Now Engineers Military SimulationsโผGame Design Grad is System Engineer for Military Simulations
A Full Sail University game design graduate is working as a systems engineer building military simulations, the school reports. The story highlights how video game development skills are being applied to defense training technology, as armed forces increasingly use simulation software modeled on commercial gaming tools.
- 4Siemens pulls open access to Radioss simulation codeโOpenRadioss is not open anymore https://www.siemens.com/en-us/products/simcenter/mechanical-simulation/radioss/rd/ # Hac
Discussion is growing around claims that OpenRadioss, the open-source crash and structural simulation code originally released under the Radioss solver, is no longer openly available. People are pointing to a Siemens Simcenter page for Radioss, suggesting access to the source has been restricted, and questioning what this means for the open-source engineering community.

OpenRadioss, the open-source crash and impact simulation code forked from Altair's Radioss, is at the centre of concerns that it may no longer remain truly open. Attention follows Siemens' Radioss product page, prompting developers and engineers to question the project's licensing and governance, and what the change means for anyone relying on the free solver in their simulation workflows.
- 6Zenithon AI Aims to Simulate Extreme Physics a Million Times FasterโผA Million Times Faster: Zenithon AI's Quest to Simulate Extreme Physics
Zenithon AI is presenting itself as a startup working on simulating extreme physics up to a million times faster than existing methods. The company appears in startup database listings, but little verified detail is available about its technology, funding, or team. The claim of such a large speed increase in physics simulation would, if proven, be significant for engineering and scientific research.
- 7Speeding up collision detection with inscribed spheresโSpeeding up the separating axis test using inscribed spheres
Box2D author Erin Catto has published a technical write-up on accelerating the separating axis test, a core algorithm in physics engines, by using inscribed spheres. The post walks through how the geometric optimization reduces the work needed to detect overlaps between shapes, an operation run millions of times per frame in games and simulations.
- 8Digital twin tech to improve ammonia-fueled vessel safetyโDigital twin technology to help improve safety of ammonia-fueled vessels
Digital twin technology is being developed to improve the safety of ammonia-fueled vessels. Ammonia is seen as a promising zero-carbon shipping fuel, but it is toxic and requires careful handling. Digital twins, virtual models that simulate real-world vessel behavior, can help engineers test safety scenarios and predict risks before ships are built or operated, supporting the maritime industry's decarbonization efforts.
