The project's website has been retired and its GitHub repository fully removed rather than archived, cutting off access to the code. Siemens frames the move as consolidating efforts into its proprietary Simcenter Radioss and Radioss R&D program. The closure is a significant loss for the open-source technical computing community and removes a tool used for CPU performance benchmarking, with no comparable free or open-source alternative currently available. ## Full article daily.dev links to this article rather than hosting it. Read it at the original source: ## Questions this post answers ### Is OpenRadioss still available as open source? No, Siemens has shut down OpenRadioss entirely. The project's website was retired and redirected to a Siemens transition page, and the OpenRadioss GitHub repository was removed rather than archived, making the source code no longer publicly accessible. Siemens now directs users toward its proprietary Simcenter Radioss and Radioss R&D program instead. _Developers tracking open-source project shutdowns and license changes can follow stories like this on daily.dev._ ### What happened to the OpenRadioss GitHub repository? The OpenRadioss GitHub repository now returns a 404 error because Siemens deleted it rather than archiving it, removing public access to the code entirely. This followed Siemens retiring the OpenRadioss website, ending four years of community-driven development after Altair originally open-sourced Radioss under the GNU AGPL license in 2022. _daily.dev helps engineers stay on top of sudden open-source project deprecations like OpenRadioss._ ### What open-source alternative exists for Radioss crash and impact simulation benchmarking? There is currently no superior free or open-source alternative to OpenRadioss for crash and impact simulation benchmarking after Siemens shut down the project and removed its code. Benchmarking work is continuing only by using previously archived local binaries of OpenRadioss rather than any actively maintained replacement. _Benchmarkers weighing their options after a tool's shutdown can track emerging alternatives on daily.dev._ ## Similar posts on daily.dev - [Cal.com Goes Close Source Because "AI Can Easily Exploit Open Source Software"](https://daily.dev/posts/cal-com-goes-close-source-because-ai-can-easily-exploit-open-source-software--onylkwl5j) · It's Foss · 0 upvotes · 0 comments - [Open source faces a security reckoning as Cal.com closes its codebase](https://daily.dev/posts/open-source-faces-a-security-reckoning-as-cal-com-closes-its-codebase-9vd2hde61) · The New Stack · 1 upvotes · 0 comments - [Cal.com just went closed source over AI, but AI is exactly why open source still wins](https://daily.dev/posts/cal-com-just-went-closed-source-over-ai-but-ai-is-exactly-why-open-source-still-wins-acr1dkvlv) · XDA Developers · 0 upvotes · 0 comments --- Tags: [#open-source](https://daily.dev/tags/open-source) [View this post on daily.dev](https://daily.dev/posts/siemens-slams-the-door-shut-on-promising-open-source-radioss-project-9zftyiai6) ```json {"@context":"https://schema.org","@graph":[{"@type":"Organization","@id":"https://daily.dev/#organization","name":"daily.dev","url":"https://daily.dev","logo":{"@type":"ImageObject","url":"https://daily.dev/apple-touch-icon.png","width":180,"height":180},"sameAs":["https://twitter.com/dailydotdev","https://github.com/dailydotdev","https://www.linkedin.com/company/daily-dev-ltd"]},{"@type":"WebSite","@id":"https://daily.dev/#website","url":"https://daily.dev","name":"daily.dev","publisher":{"@id":"https://daily.dev/#organization"},"potentialAction":{"@type":"SearchAction","target":{"@type":"EntryPoint","urlTemplate":"https://daily.dev/search?q={search_term_string}"},"query-input":"required name=search_term_string"}}]} {"@context":"https://schema.org","@type":"TechArticle","headline":"Siemens Slams The Door Shut On Promising Open-Source Radioss Project","url":"https://daily.dev/posts/siemens-slams-the-door-shut-on-promising-open-source-radioss-project-9zftyiai6","mainEntityOfPage":{"@type":"WebPage","@id":"https://daily.dev/posts/siemens-slams-the-door-shut-on-promising-open-source-radioss-project-9zftyiai6"},"datePublished":"2026-10-02T01:14:44.529Z","dateModified":"2026-10-05T16:53:09.457Z","description":"Siemens has shut down the OpenRadioss project, the open-source crash and impact simulation solver that Altair released under the GNU AGPL license in 2022.
