Connecting MOR-based boundary condition independent compact thermal models

Abstract

The inter-connection of MOR-based boundary condition independent compact thermal models of heat diffusion problems and detailed models of heat transfer problems is here shown not to be straightforward and to introduce numerical difficulties. In order to overcome this drawback, a novel definition of MOR-based boundary condition independent compact thermal models is provided, which makes their inter-connection, as straightforward as the inter-connection of Delphi-like compact thermal models. The resulting MOR-based boundary condition independent compact thermal models can be inter-connected to any detailed model of heat transfer problems and/or to any other MOR-based boundary condition independent compact thermal models, without limitations. The approach is verified analysing a Package on Package application.
