The Integrator object is used for the following:

The system of nonlinear equations is of the form:

Static analysis:

Transient analysis:

The type of integrator used in the analysis is dependent on whether it is a static analysis or transient analysis:



  • Hilbert-Hughes-Taylor Method (HHT)

*NOTE: static integrators should only be used with a Linear TimeSeries object with a factor of 1.0.
