Connected circuit
Methods of analysis: reminder
The analysis methods of the electric circuit are those mentioned above:
 method of mesh currents in the Flux 2D solver
 method of the node integrated potentials in the Flux 3D
To apply these methods, a certain number of constraints must be respected. These constraints are described in the following blocks.
Connected circuit: definition
A connected circuit is a circuit in which there is a path between any two nodes (allowing passage from any node to any other node by a path).
Constraints ( former 2D)
Constraints (in former 2D) are the following:
 only one current source by mesh
 description of a connected electric circuit
To describe several electric circuits (in 2D) and keep the condition of connected circuit, it is necessary to add a connection between the circuits as that is presented in the figure below.
These connections bear no influence on the electric behavior of the electric circuit.
