  • What's New

    View new features for Radioss 2019.

  • Overview

    Radioss® is a leading explicit finite element solver for crash and impact simulation.

  • Tutorials

    Discover Radioss functionality with interactive tutorials.

  • User Guide

    This manual provides details on the features, functionality, and simulation methods available in Altair Radioss.

    • Run Radioss

      The execution of Radioss is described here.

    • Explicit Structural Finite Element Analysis
      • Time Step

        An explicit is solved by calculating results in small time increments or time steps. The size of the time step depends on many factors but is automatically calculated by Radioss.

      • Finite Elements
      • Modeling Tools
      • Materials

        Different material tests could result in different material mechanic character.

      • Failure
      • Composites

        Composite materials consist of two or more materials combined each other. Most composites consist of two materials, binder (matrix) and reinforcement. Reinforcements come in three forms, particulate, discontinuous fiber, and continuous fiber.

      • Connections
        • Spotweld (Bolt or Adhesive Connect)
        • Bolt Modeling for Crash
      • Kinematic Constraints

        In Radioss, a kinematic condition is a nodal constraint applied to a set of nodes.

      • Interfaces

        Several interfaces are available in Radioss, this section deals with contact interfaces only. Each interface is distinguished with a type number.

      • Loads

      • Airbag Modeling

        This section deals with airbags model implemented into the F.E. code in Radioss v9.0.

      • Debugging Guidelines
      • Appendix
    • Implicit Structural Finite Element Analysis
    • Fluid and Fluid-Structure Simulation
    • Smooth Particle Hydrodynamics (SPH)
    • Multi-Domain Technique
    • Design Optimization

      Optimization in Radioss was introduced in version 13.0. It is implemented by invoking the optimization capabilities of OptiStruct and simultaneously using the Radioss solver for analysis.
