/IMPL/LSEARCH/N – Line Search Methods

Description

Line search methods for nonlinear analysis.

Format

/IMPL/LSEARCH/N

MAX_ls    TOL_ls

Data

Description

N

= 0: set to 3

= 1: Standard line-searches minimizing energy residual

= 2: Line-searches minimizing force residual

= 3: Automatic choice between method 1 and method 2 according to Itol defined in /IMPL/NONLINEAR

MAX_ls

Maximum line search iteration number

Default = 20

TOL_ls

Tolerance for line search iteration

Default =1.0e-3

Comments

1.The method N=1 is suitable with material nonlinear analyses (from version 10-SA1-202). The old method N=3 is suitable with general nonlinear analyses with contact.
