Altair Radioss is a multidisciplinary finite element solver developed by Altair Engineering. It includes implicit and explicit time integration schemes for the solution of engineering problems, from [[linear] statics and linear dynamics to non-linear transient dynamics and mechanical systems. The multidisciplinary solver has its main strengths in durability, NVH, crash, safety, manufacturability, and fluid-structure interaction.
Since the 2021 release, Radioss has supported input in the LS-DYNA input format as well as the Radioss 'Block' Format
OpenRadioss, a source available software version of Radioss, sharing the capabilities, input and output formats of Altair Radioss, was released on September the 8th 2022. Despite being called open source software, the software cannot be compiled or used without a library that is provided only in binary form, and for which third parties are granted "limited permission to use".
