This command is used to construct the Integrator object. The Integrator object determines the meaning of the terms in the system of equation object Ax=B.
The Integrator object is used for the following:
* determine the predictive step for time t+dt * specify the tangent matrix and residual vector at any iteration * determine the corrective step based on the displacement increment dU
The type of integrator used in the analysis is dependent on whether it is a static analysis or transient analysis.
Static Integrators:
Transient Integrators:
