Customize Block Display
The following shows a complete example of a component file with annotation and the
resulting library block and dialog box. The image file,
custom_spring.jpg, is located in the same folder as the component
file. This example is an illustration of all the techniques described in Customizing the Block Name and Appearance.
component spring
% Rotational Spring
% This block implements a simple rotational spring.
nodes
r = foundation.mechanical.rotational.rotational; % rod
c = foundation.mechanical.rotational.rotational; % case

annotations

c : Side = right;

parameters
k = { 10, 'N*m/rad' }; % Spring rate
end
variables
theta = { 0, 'rad' }; % Deformation
t = { 0, 'N*m' }; % Torque
w = { 0, 'rad/s' }; % Angular velocity
end

end

t == k * theta;
w == theta.der;
