*COMBINATORIAL RULE

Define controls associated with combinatorial rules to derive interaction properties from surface properties.

This option is used to define controls associated with combinatorial rules that are used to determine interaction properties as functions of surface properties.

This page discusses:

Optional parameters

ALPHA
Set this parameter equal to α in the equation μAB=[1+α(1−μAμB)]μA, where μA≤μB, to compute a friction coefficient for contact, μAB, based on friction coefficients μA and μB specified as surface properties.
ANISOTROPY WEIGHTING
This parameter applies only if friction anisotropy is specified as a surface property.

Set ANISOTROPY WEIGHTING=BALANCED to specify a balanced weighting method for combining surface-based directional preferences for the anisotropic friction model.

Set ANISOTROPY WEIGHTING=PROPORTIONAL to specify an epsilon-proportional weighting method for combining surface-based directional preferences for the anisotropic friction model.

Set ANISOTROPY WEIGHTING=DOMINANT to specify the maximum-epsilon-dominant weighting method for combining surface-based directional preferences for the anisotropic friction model.

There are no data lines associated with this option.
