Efficient Force Analysis in CAD-Based Simulations

The paper presents a BEM-based approach for efficient force analysis of the steady-state field problems. As an extension to the minimal-order H-phi formulation we introduce here an improved approach for the treatment of the skin-effect problems. This approach enables the designers to perform the CAD-based simulations without any additional modeling requirement. The classical BEM modeling methodology is combined with the multipole-based integral technique (MBIT) to accelerate/compress the densely populate BEM matrix. The verification of the discussed approach is done by comparison with the known analytical solutions. The proposed method is illustrated on the problems dealing with the force calculation in the real-world bus-bars systems.
