A type of Integrator
Properties
TimeStep: number (s), optionalcoming soon
The fixed time step used by the integrator. It must be set as a divisor of the output time-step and external controller communication interval.
Tolerance: number, optionalcoming soon
When the "Maximum number of iterations" > 1, the integrator relative tolerance is used to control how many iterations are carried out when integrating the first order and prescribed second order states. Iterations are carried out until the maximum number of iterations is reached, or until the change in all first order and prescribed state derivatives between successive iterations is less than the relative tolerance multiplied by the state derivative absolute value.
default = 0.005
IntegratorType: stringcoming soon
Defines the specific type of Integrator model in use. For a ImplicitNewmarkBetaFixedStep object, this must always be set to a value of ImplicitNewmarkBetaFixedStep.
MaximumNumberOfIterations: integer, optionalcoming soon
The maximum number of iterations for prescribed freedoms and first order states (e.g. dynamic stall & wake). A value of 1 may sometimes inprecisely integrate first order states
default = 1
Beta: number, optionalcoming soon
The β parameter for the Newmark-β integration method. The recommended value of 0.25 (with a γ value of 0.50) results in the constant average acceleration method that is unconditionally stable for linear systems. A value of 0.26 (with a γ value of 0.52) results in a method that is close to the constant average acceleration method but includes a small amount of numerical damping to reduce unwanted vibrations of high-frequency modes. Note that the numerical damping increases with the step size.
default = 0.25
Gamma: number, optionalcoming soon
The γ parameter for the Newmark-β integration method. The recommended value depends on the β parameter and given by the formula γ = 2.sqrt(β) - 0.5. Values higher than 0.5 introduce positive numerical damping, whereas lower values introduce negative numerical damping.
default = 0.5
ToleranceMultiplier: number, optionalcoming soon
The tolerance used for defining the convergence criteria of the Newton-Raphson equilibrium iterations for 1st and 2nd order states. Reduced values of this parameter result in more iterations and more accurate solutions, whereas increased values result in less iterations and less accurate solutions, which eventually may cause stability problems. The allowable range of values for this parameter is 0.001 to 1000.
default = 1
