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, an open-source version of Radioss under the GNU AGPL license. OpenRadioss shares the capabilities, input and output formats of Altair Radioss. OpenRadioss was released on September the 8th 2022. OpenRadioss uses an external library that is partly provided in binary form. This external library contains open-source software like lapack and C++ Mathematical Expression Toolkit Library. But also free software like md5, zlib, and Altair's library for their h3d extension.
