Abstract In systems modeling, the dynamic behavior is approximated by considering certain properties to be constant in space in each physical component of the system. Such models are called lumped element models and are composed of connected components. Each component is described by ordinary differential equations and algebraic equations. The theory of linear graphs or model graphs can be helpful for analysis of such models. This paper presents a unified methodology for describing and analyzing network topology, using both linear graphs and the underlying algebraic equations, i.e. to take advantage of linear graph methods to enhance symbolic manipulation of model equations in order to handle underdetermined sets of potential variables and overdetermined sets of flow variables. The methodology is extended to handle overdetermined potential variables which arise, for example, when dealing with 3D rotations in multi body systems. It also allows handling of planar loops without any special attention by the user. This methodology for treating lumped models is in particular applicable to Modelica tools and would in certain cases allow simulation of ungrounded circuits and otherwise enable better diagnostics, for example when forgetting to ground an electrical circuit. It will also simplify the Multibody library of Modelica Standard Library.

About National Digital Library of India (NDLI)
NDLI logo

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
