!AUTOINC_PARAM

Specifies automatic increment parameters.

Parameters

Parameter Type Description
NAME C Automatic increment parameter name (required)

** Second line **

Specifies the reduction conditions and the corresponding time-increment reduction factor.

    (2nd line)  RS, NS_MAX, NS_SUM, NS_CONT, N_S
Variable Type Description
RS R Time-increment reduction factor (default: 0.5)
NS_MAX I Threshold for the maximum number of Newton-method iterations (default: 20)
NS_SUM I Threshold for the total number of Newton-method iterations (default: 100)
NS_CONT I Threshold for the number of contact iterations (default: 10)
N_S I Number of substeps until the reduction condition is satisfied (default: 2)

** Third line **

Specifies the increase conditions and the corresponding time-increment increase factor.

    (3rd line)  RL, NL_MAX, NL_SUM, NL_CONT, N_L
Variable Type Description
RL R Time-increment increase factor (default: 1.75)
NL_MAX I Threshold for the maximum number of Newton-method iterations (default: 10)
NL_SUM I Threshold for the total number of Newton-method iterations (default: 50)
NL_CONT I Threshold for the number of contact iterations (default: 5)
N_L I Number of substeps until the increase condition is satisfied (default: 2)

** Fourth line **

Configures cutback.

    (4th line)  RC, N_C
Variable Type Description
RC R Time-increment reduction factor at cutback (default: 0.25)
N_C I Maximum allowable number of consecutive cutbacks (default: 5)
