GeneralizedAlphaIntegrator

GeneralizedAlphaIntegrator(alpha_m: float, alpha_f: float, gamma: Optional[float] = None, beta: Optional[float] = None)

Bases: TransientIntegrator

Generalized Alpha transient integrator.

GeneralizedAlphaIntegrator implements the Generalized Alpha dynamic integration method, providing user-controlled high-frequency numerical dissipation while minimizing low-frequency dissipation.

Tcl form

integrator GeneralizedAlpha <alphaM> <alphaF> <gamma> <beta>

Example

from femora.core.model import Model

model = Model()
integ = model.analysis.integrator.generalizedalpha(alpha_m=0.5, alpha_f=0.5)

Create a GeneralizedAlpha transient integrator.

Parameters:

Name	Type	Description	Default
`alpha_m`	`float`	Alpha_M parameter.	required
`alpha_f`	`float`	Alpha_F parameter.	required
`gamma`	`Optional[float]`	Gamma parameter. Defaults to `0.5 + alpha_m - alpha_f`.	`None`
`beta`	`Optional[float]`	Beta parameter. Defaults to `(1.0 + alpha_m - alpha_f)**2 / 4.0`.	`None`
