In this release, the main focus remains on expanding the coverage of the LS-DYNA input reader, a critical feature to make the code even more accessible and ease its adoption by a broader community of users. It is now possible to mix input using include files from both solver formats. We better cover options dealing with biomechanics to support Human Body Models, aimed for virtual testing in crashworthiness. Composite materials coverage is improved, crucial for Aero and Auto.

An important domain for which Radioss is well recognized is the modeling of failure of materials, with the so-called non-local damage method.

In 2023 release, additional failure models dedicated to composite materials have been added : 

  • /FAIL/HOFFMAN
  • /FAIL/MAX_STRAIN
  • /FAIL/TSAIHILL
  • /FAIL/TSAIWH

There is also a new output to display damage for each failure model (/H3D/ELEM/FAILURE/<FAIL_ID>).

New element quality criteria are implemented in solid properties to trigger element deletion or switch to SPH:

  • Vdef_min : minimum volume ratio
  • Vdef_max : maximum volume rario
  • ASP_max : maximum aspect ratio
  • COL_min : minimum collapse value

Please check the release notes for all new features and enhancements.

Since the launch of OpenRadioss on September 2022, Radioss establishes itself as the open alternative for crash & impacts, democratizing explicit dynamics and increasing innovation pace, leveraging its fast growing worldwide community, while maintaining a highly professional code with the commercial version under dual license, maintained by the internal development team.

OpenRadioss Users’ day was held in Aachen on June 27th, Germany. With more than 200 participants, it was a true success less than a year after the open-source of the code.
