Engine Keyword In this group of keywords are used to generally define the output style, control of computation, damping and ALE setup
during the computation.
Generates animation files containing results according to the keywords specified. The keywords are specified in the
topics within Animation and Post-processing Output Files.
Engine Keyword In this group keywords are used for implicit solution. Different implicit solver methods (linear, nonlinear, buckling
or quasi-static), different options to control the implicit computation, different implicit time step method and
implicit output messages are introduced.
Engine Keyword Due to some linearization used in geometrical nonlinear analysis, small time step has to be chosen to avoid accumulated
errors under large rotation. In this case, this option improves the accuracy using usual time step.
Engine Keyword In this group, keywords are used to define the kinematic condition (constrain/release rotation or translation DOF)
and initial condition (rotational/translational velocity).
Engine Keyword In this group, keywords are used to define different time step control (STOP, KILL, CST or DEL, etc.) for different entities (shell, brick, beam, airbag, interface, etc.) during the computation.
Engine Keyword In this group, keywords are used to output different info (like stress, strain, orthotropy direction, temperature,
etc.) in state file (STA-File).
Optimization Keyword This manual contains the description of the keywords for the Radioss optimization. This manual is compatible with the version 2018 of Radioss.
Engine Keyword In this group keywords are used for implicit solution. Different implicit solver methods (linear, nonlinear, buckling
or quasi-static), different options to control the implicit computation, different implicit time step method and
implicit output messages are introduced.
/IMPL/BUCKL/1 Engine Keyword Euler buckling modes will be computed.
/IMPL/BUCKL/2 Engine Keyword Euler buckling modes will be computed based on actual pre-stress stat.
/IMPL/LBFGS/L Engine Keyword Change the maximum number of BFGS quasi-Newton method for implicit nonlinear.
/IMPL/LINEAR Engine Keyword Linear implicit solution will be computed.
/IMPL/LRIGROT Engine Keyword Due to some linearization used in geometrical nonlinear analysis, small time step has to be chosen to avoid accumulated errors under large rotation. In this case, this option improves the accuracy using usual time step.
