CIRCUIT NETWORK ANALYSIS USING ALGEBRAIC MULTIGRID APPROACH

摘要

A technique is provided for applying an algebraic multigrid method to analysis of circuit networks with regular and irregular circuit patterns (Figure 1). Smothing is performed at each level in the restriction process from the finest level (110) to the coarsest level (130) and in the interpolation process from the coarsest level (130) to the finest level (110). Adaptive processing may be applied to the grid coarsening and error smoothing operations to increase the processing speed.
