# block contact compute-stiffness command

Syntax

block contact compute-stiffness keyword

Primary keywords:

Automatically compute normal and shear stiffness for subcontacts based on stiffness and size of adjacent zones (see Joint Properties). The average stiffness for all subcontacts in a contact is calculated and assigned. Subcontacts must exist and a joint constitutive model must have been assigned that has properties stiffness-normal and stiffness-shear.

shear-factor f

Set a multiplier for the shear stiffness. The shearr stiffness will be set equal to f times the normal stiffness. By default f = 1.

maximum f

Set a maximum stiffness. This is useful if there are very small zones that may cause very large stiffnesses.
