*Non Linear Static

Previous pageNext page

Purpose

To specify solution parameters used in the final static analysis performed automatically by Flexcom following a frequency domain dynamic analysis.

Theory

Refer to Static Solution for further information on this feature.

Keyword Format

One line with the appropriate solution parameters, all of which are optional:

[Number of Steps] [, Required Tolerance Measure] [, Maximum Number of Iterations]

This keyword is only relevant for frequency domain dynamic analysis. Number of Steps defaults to 1. Required Tolerance Measure defaults to 0.001. Maximum Number of Iterations defaults to 20.

Table Input

Input:

Description

Number of Steps:

The number of analysis steps used in the final static analysis phase of the overall solution. This defaults to a value of 1.

Required Tolerance Measure:

The tolerance used in determining if convergence has been achieved between successive iterations. The default value is 0.001 (0.1%).

Maximum Number of Iterations:

The maximum number of iterations that may be performed. The default number of iterations is 20.

Notes

(a)The default values are adequate in the vast majority of cases and this option is rarely invoked.

(b)If the specified number of steps is 1, then the static forces comprising the load vector are applied initially at their full magnitudes, and the solution is completed in one step. If the Number of Steps is specified as greater than 1, then the static loads are increased up to their maximum values over the specified number of steps.
