Syntax

integrator GeneralizedAlphaExplicit (1) [2]
integrator GeneralisedAlphaExplicit (1) [2]
# (1) int, unique integrator tag
# [2] double, spectral radius, \rho_\infty, default: 0.5

Remarks

If the model is linear elastic, it is possible to indicate using

set linear_system true

to speed up the computation.

!!! Warning When $ho_\infty<1$, the algorithm extrapolates.
