Brick Attributes: Pre-load

Description

Assigns pre-load as either pre-stress or pre-strain to selected brick elements.

Pre-load is applied in the direction of the local x, y and z axes of the brick. If the brick does not have local axes assigned, the directions revert to the global XYZ axes.

A positive value of pre-load causes an unrestrained element to contract.

A negative value of pre-load causes the element to stretch.

Pre-load attributes are load case dependent.
