In 20-sim you can easily create your own bond graph elements. The process of creation consists of three parts:
1. | For any bond connected to your submodel an internal port has to be defined. For each port you have to specify some data: |
• | The physical domain. |
• | The size. |
• | The orientation. |
• | The causality. |
2. | Create the icon for the component. This can be done with a specialized drawing editor. |
3. | Create the element description. This can be done by (differential) equations or by a bond graph. |
