`struct.link.model.disp`

Syntax

- m := struct.link.model.disp(p<,idof>)
Get the relative displacement between the node and the target used by each 1-D force-displacement model. Will return a 6x1 matrix with the values in all six degrees-of-freedom, or if the optional idof argument is provided, the value in one specific degree-of-freedom.

Note that displacements are with respect to the node-local coordinate system. The relative displacement is defined as the displacement of the link target minus the the displacement of the link host node in the node local coordinate system.

Returns: m - a 6x1 matrix representing the relative displacement seen by each force-displacement model, or a single value in a specific degree-of-freedom

Arguments: p - a structural link pointer
