ParallelDisplacementControl Integrator

The ParallelDisplacementControl integrator is a static integration method that controls the displacement at a specific degree of freedom during analysis, optimized for parallel processing.

Description

This integrator is particularly suitable for:

Static analysis with prescribed displacement targets in parallel computing environments
Large-scale models that require distributed processing
Post-peak analysis in nonlinear structures with parallel computing
High-performance computing applications

The ParallelDisplacementControl method is similar to DisplacementControl but is designed specifically for efficient parallel processing.

Parameters

The ParallelDisplacementControl integrator requires the following parameters:

Parameter	Description	Default	Notes
node_tag	Tag of the controlling node	None	Required
dof	Degree of freedom at the node (1-ndf)	None	Required
incr	First displacement increment	None	Required
num_iter	Number of iterations desired	1	Optional
min_incr	Minimum step size allowed	incr	Optional, defaults to incr value
max_incr	Maximum step size allowed	incr	Optional, defaults to incr value
