New and modified features in Radioss.
The Smooth Particle Hydrodynamics method formulation is used to solve the equations of mechanics, when particles are free from a meshing grid.
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 Radioss, two node types are available. They use Cartesian coordinate to describe the position of each node.
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 Monitored volumes can be used to model an airbag, tire, tank, or any closed volume.
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 Define the flux output elementary boundary condition used with /MAT/LAW151.
Block Format Keyword Describes the elementary boundary condition of zero pressure gradient. This keyword is not available for SPMD parallel version.
Block Format Keyword Describes the elementary boundary condition of initial pressure.
Block Format Keyword Describes the elementary boundary condition of initial velocity.
Block Format Keyword Define the inlet elementary boundary condition used with /MAT/LAW151.
Block Format Keyword Describes the elementary boundary conditions.
Block Format Keyword Describes the elementary boundary condition of imposed normal velocity.
Block Format Keyword Define a non-reflecting Frontier for ALE or EULER flow applied on a given boundary surface.
Block Format Keyword Describes the elementary boundary condition to imposed density and pressure.
Block Format Keyword Describes the elementary boundary condition to describe inlet valve (imposed density and pressure).
Block Format Keyword Describes the elementary boundary condition to describe outlet valve (imposed density and pressure).
Block Format Keyword Describes the elementary boundary condition of imposed velocity.
Block Format Keyword Describes the ALE rigid wall.
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.
