This article provides an overview of the updates introduced in the 2023 version and later releases of Altair Radioss. For full details, please refer to the attached presentations and Altair documentation.

 

Version 2023.1

Altair Radioss v2023.1 Feature Updates - Presentation

Altair Radioss v2023.1 Documentation - What's New

/MAT/LAW122 is a new unidirectional composite ply model accounting for orthotropic elasticity and plasticity. The material accounts for both fiber and matrix damage, including strain rate effects.

 

 

/MAT/LAW124 is a new concrete material law accounting for plasticity, damage, and strain rate effects, based on the Concrete Damage Plasticity Model 2 (CDPM2) formulation. It incorporates multiple phenomena while requiring only a few mandatory parameters, making the constitutive model easy to use.

 

/LOAD/PCYL defines a pressure load in a cylindrical system on a surface as a function of radius, time and angle of incidence.

 

 

Version 2023

Altair Radioss v2023 Feature Updates - Presentation

Altair Radioss v2023 Documentation - What's New

This version introduces several new failure models for composites, including /FAIL/HOFFMAN, /FAIL/MAX_STRAIN, /FAIL/TSAILHILL and /FAIL/TSAIWU.

 

/H3D/NODA/CSE_FRICG, /H3D/NODA/CSE_FRIC/INTER=I or ALL is a new output to display contact friction surface energy.

 

/PROP/TYPE14 introduces a new flag, Iale, to activate the ALE (Arbitrary Lagrangian-Eulerian) and Eulerian formulations for solids elements. This option replaces the /ALE/MAT and /EULER/MAT cards.

/PROP/TYPE14 includes new element quality criteria that can trigger element deletion or switch to SPH (SOL2SPH)

  • Vdef_min: Minimum volume ratio
  • Vdef_max: Maximum volume ratio
  • ASP_max: Maximum aspect ratio
  • COL_min: Minimum collapse value
