This manual provides a list of all the model definition keywords and options available in Radioss.
Block Format Keyword
Block Format Keyword In this group, keywords are used to set default value, global parameter, analysis type, input/output print, damping and ALE and CFD treatment for the whole model. For default value, it is still possible to overwrite in each specific keywords.
Block Format Keyword In this group, keywords are used to set Rayleigh mass and stiffness damping coefficients, which apply to a set of nodes used to stabilize the results.
Block Format Keyword Describes the treatment of element closure.
Block Format Keyword This card enables you to define grid formulation for ALE modeling. ALE domain can have moving boundaries. Grid must also be updated on each cycle to map the new geometrical domain. This update is not unique and can be arbitrary. Grid points are updated on each cycle depending on formulation type provided by you.
Block Format Keyword The displacement of a grid node depends on the displacements of the neighboring grid nodes.
Block Format Keyword Velocity of a given grid node depends on velocity and displacements of neighboring grid nodes.
Block Format Keyword Grid nodes are connected with nonlinear springs (those springs have no effect on the material, only on the movement of the grid).
Block Format Keyword Describes the standard formulation for ALE grid velocity computation.
Block Format Keyword Describes the Euler formulation.
Block Format Keyword This option allows for a second order MUSCL (Monotonic Upstream-Centered Scheme for Conservation Laws) reconstruction of volumic fraction fields when using Multi-Material laws (LAW51), and for a full second order scheme (time and space) when using material LAW151.
Block Format Keyword Describes the computation Aero-Acoustic formulation for Eulerian or quasi-Eulerian simulations. Internal forces are computed with finite volume formulation. It improves results for under integrated elements. By default artificial viscosity is canceled, (qa,qb) default values are zero.
Block Format Keyword In Radioss, two node types are available. They use Cartesian coordinate to describe the position of each node.
Block Format Keyword
Block Format Keyword In this group, keywords are used to combine material and property information (/PART), assemble model (/SUBSET) or define a separate model (//SUBMODEL).
Block Format Keyword Interfaces solve the contact and impact conditions between two parts of a model. Several interface types are available in Radioss and use different contact treatments.
Block Format Keyword
Block Format Keyword Monitored volumes could be used for airbag or tire. The monitored volumes must be inside of closed surface.
Block Format Keyword Radioss supports several different kinematic constraints, which are mainly used to impose acceleration, velocity, displacement or temperature in structure or constraint the moving of structure. They are mutually exclusive for each degree-of-freedom (DOF). Two kinematic conditions applied to the same node may be incompatible.
Block Format Keyword In Radioss the following load cases are available. Stress/strain as initial state could be considered by modeling, as well as pressure, gravity, and thermal load.
Block Format Keyword In this group, tools like transformation, frames, skews, and curve are introduced.
Block Format Keyword Keywords in this group are used to define how to select a group of node, part, elements, lines, or surfaces.
Block Format Keyword Adaptive Meshing is used in metal forming to divide the element to better describe the geometry. /ADMESH/GLOBAL and /ADMESH/SET are not available for SPMD computation.
Block Format Keyword Time histories output for different element groups, section output, or gauge output are described in this group.
Block Format Keyword Keywords that are still supported, but no longer maintained (*) are considered obsolete.
