I have a complex model in Modelica. As I have lots of components in my model, I want to define classes and include some components inside the classes to reduce the complexity of the model. Since I couldn`t find online an example of the use of classes which are used in Modelica, could you give an idea how to define classes in Modelica?
The code is as follows;
model HD_3Kolben_bsp

Real opening_HP_3;
