Driving a coupled field-circuit problem
Purpose - The paper addresses various ways of driving a magneto-quasi-static coupled field-circuit problems, starting with the underlying assumptions of this problem class. It focuses on problem consistency, supporting both conceptual understanding, and translation into software. Design/methodology/approach - The paper proceeds from a precisely defined problem class and analyze its consistency with homology theory. Findings - Precise notion of "driving a problem," extensive discussion of modeling assumptions and decisions, and classification and consistency analysis of various driving methods. Practical implications - Helps modelers systematically pose consistent coupled field-circuit problems. The computation of homology groups can be automated to help pose problems and detect consistency problems. Originality/value - Starting from the basic underlying assumptions, the paper summarizes logically the application of homology to consistency analysis. The style is tutorial for modelers, with numerous particular cases.
