GAPOFFS

<YES, NO, AUTO>

Default = AUTO

This parameter is used to control frictional offset for gaps and contact elements in linear and small displacement nonlinear analyses.

If YES, frictional offset for gaps and contact elements is active in linear and small displacement nonlinear analysis subcases.

If NO, frictional offset for gaps and contact elements is inactive in linear and small displacement nonlinear analysis subcases.

If AUTO:

For gap and N2S contact elements:

Frictional offset is turned OFF when the deck contains gaps, N2S contact with friction or stick conditions and at least one nonlinear subcase. This affects both linear and small displacement nonlinear subcases.

For S2S contact elements:

Frictional offset is turned ON for elements in linear analysis subcases (static, normal modes, frequency response, and so on) and turned OFF for elements in small displacement nonlinear analysis.

Note:

This parameter is ignored for contact elements in large displacement nonlinear analysis as frictional offset is always taken into account in such cases.
