| Abstract | In this paper we investigate the potential-based finite element algorithms for eddy-current problems. In our models the source coil carries a pulse excitation current generating a transient field. As distinguished from the traditional coupled algorithm whose discrete equation system including both vector and scalar potential unknowns is solved at every time-step, a novel decoupled algorithm is presented here. Because the vector and scalar unknowns are calculated at two different equation systems respectively, it decreases the storage amount of non-zero entries of coefficient matrix and computational costs, and achieves the better results under the alike CPU time. Some computer simulation results of eddy-current densities for two eddy-current models (IEEJ model and TEAM Workshop Problem 7) are demonstrated to verify the feasibility and efficiency of our algorithm. |

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.
