Altair Radioss is a multidisciplinary finite element solver developed by Altair Engineering.[1] It can solve both linear and non-linear problems. It is a finite element solver using implicit and explicit integration schemes for the solution of engineering problems, from linear statics and linear dynamics to nonlinear transient dynamics and mechanical systems. This multidisciplinary solver enables designers to maximize performance related to durability, NVH, crash, safety, manufacturability, and fluid-structure interaction, in order to bring products to market faster.
Since the 2021 release, Radioss has supported input in the LS-DYNA input format as well as the Radioss 'Block' Format [2]
OpenRadioss, an open source version of Radioss, sharing the capabilities, input and output formats of Altair Radioss, was released on September the 8th 2022. [3]
