Altair Radioss is a multidisciplinary finite element solver developed by Altair Engineering.[1] 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 [2]
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,[3] 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".
