Radioss® is a leading explicit finite element solver for crash and impact simulation.
Discover Radioss functionality with interactive tutorials.
The Radioss solver can be executed using different methods described here.
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.
Different material tests could result in different material mechanic character.
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.
In Radioss, a kinematic condition is a nodal constraint applied to a set of nodes.
Several interfaces are available in Radioss, this section deals with contact interfaces only. Each interface is distinguished with a type number.
Airbags are modeled as monitored volumes /MONVOL in several different ways.
In this section, fluid and fluid-structure simulation is presented.
The Smooth Particle Hydrodynamics method formulation is used to solve the equations of mechanics, when particles are free from a meshing grid.
The objective of the Multi-Domain technique (also referred to as RAD2RAD) is to optimize the computing performances of large scale Radioss models.
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.
This section is comprised of error messages in ascending numerical order.
This section is comprised of warning messages in ascending numerical order.
