Combination Approach of FEM and Circuit System in Voltage Drop Analysis

An approach for implementing the combination of solving the current field and the circuit system is presented in this paper. By employing the concept of super-node, the matrix of the conventional nodal analysis of circuit system is transformed from non-positive define to positive define first. Then a positive define combined matrix of the nodal analysis and the finite element method is obtained
