function [stewart] = initializeAmplifiedStrutDynamics(stewart, args)
% initializeAmplifiedStrutDynamics - Add Stiffness and Damping properties of each strut
%
% Syntax: [stewart] = initializeAmplifiedStrutDynamics(args)
%
% Inputs:
% - args - Structure with the following fields:
% - Ksi [6x1] - Vertical stiffness contribution of the piezoelectric stack [N/m]
% - Csi [6x1] - Vertical damping contribution of the piezoelectric stack [N/(m/s)]
% - Kdi [6x1] - Vertical stiffness when the piezoelectric stack is removed [N/m]
% - Cdi [6x1] - Vertical damping when the piezoelectric stack is removed [N/(m/s)]
%
% Outputs:
% - stewart - updated Stewart structure with the added fields:
% - Ki [6x1] - Total Stiffness of each strut [N/m]
% - Ci [6x1] - Total Damping of each strut [N/(m/s)]
% - Ksi [6x1] - Vertical stiffness contribution of the piezoelectric stack [N/m]
% - Csi [6x1] - Vertical damping contribution of the piezoelectric stack [N/(m/s)]
% - Kdi [6x1] - Vertical stiffness when the piezoelectric stack is removed [N/m]
% - Cdi [6x1] - Vertical damping when the piezoelectric stack is removed [N/(m/s)]
