Some definitions

Bong Graph Modeling

Is the representation (by a bond) of power flows as products of efforts and flows with elements acting between. These variables and junction structures to put the system together.

Bond graphs are labeled and directed graphs, in which the vertices represent submodels and the edges represent an ideal energy connection between power ports.

The vertices

The vertices are idealized descriptions of physical phenomena: they are concepts, denoting the relevant aspects of the dynamic behavior of the system.

The edges

The edges are called bonds. They denote point-to-point connections between submodel ports.

The bond transports a power as product of two generic energy variables

Which generic variables are used ?
