- Smooth Particle Hydrodynamics (SPH)
The Smooth Particle Hydrodynamics method formulation is used to solve the equations of mechanics, when particles are free from a meshing grid.
- Computational Fluid Dynamics (CFD)
- General Controls
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.
- Nodes
Block Format Keyword In Radioss, two node types are available. They use Cartesian coordinate to describe the position of each node.
- Elements
Block Format Keyword
- Component and Parts Organization
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).
- Interfaces
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.
- Materials
- Properties
Block Format Keyword
- Monitored Volumes (Airbags)
Block Format Keyword Monitored volumes can be used to model an airbag, tire, tank, or any closed volume.
- Constraints
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.
- Load Cases
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.
- Tools
Block Format Keyword In this group, tools like transformation, frames, skews, and curve are introduced.
- Groups(Sets)
Block Format Keyword Keywords in this group are used to define how to select a group of node, part, elements, lines, or surfaces.
- Adaptive Meshings
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.
- Output Database
Block Format Keyword Time histories output for different element groups, section output, or gauge output are described in this group.
- Obsolete
Block Format Keyword Keywords that are still supported, but no longer maintained (*) are considered obsolete.
