Abstract: An information processing apparatus performs electromagnetic field analysis over a plurality of stages. The information processing apparatus includes a hardware processor connected to a memory. The hardware processor sequentially selects an analysis target and determines one or more analysis regions in the analysis target. The one or more analysis regions are determined on the basis of a parameter relative to mutual influence between structures included in the analysis target. The hardware processor performs electromagnetic field analysis on the one or more analysis regions. The structures include a first structure and a second structure. At least one of the one or more analysis regions includes an entirety of the first structure and part of the second structure.

Abstract: An electromagnetic field simulator performs: a model creation information extraction process; a model automatic creation process; and an electromagnetic field analysis process. The model creation information extraction process includes: obtaining evaluation frequency information that includes an evaluation frequency for an apparatus suffering noise; obtaining target material information of a determination target; determining whether a conductive component is present in the obtained target material information; and determining the conductive component as having an antenna operating portion that operates as an antenna if the conductive component is present in the obtained target material information. The model automatic creation process includes: creating the model to have a simplified shape except for the component to be determined determined as having the antenna operation portion of the component. The electromagnetic field analysis process includes: performing electromagnetic field analysis on the created model.
