NewmarkIntegrator

NewmarkIntegrator(gamma: float, beta: float, form: str = 'D')

Newmark method transient integrator.

NewmarkIntegrator implements the classical Newmark-beta implicit method for second-order structural dynamic time-history equations.

Tcl form

integrator Newmark <gamma> <beta> [-form <D|V|A>]

Example

from femora.core.model import Model

model = Model()
integ = model.analysis.integrator.newmark(gamma=0.5, beta=0.25, form="D")

Create a Newmark transient integrator.

Parameters:

Name	Type	Description	Default
`gamma`	`float`	Gamma dynamic integration parameter.	required
`beta`	`float`	Beta dynamic integration parameter.	required
`form`	`str`	Primary formulation variable. 'D' for displacement (default), 'V' for velocity, or 'A' for acceleration.	`'D'`

Raises:

Type	Description
`ValueError`	If form is not 'D', 'V', or 'A'.
