| Abstract | A modified form of Laplace's equation, based on coordinate stretching, is proposed, that lends itself to a new convenient numerical grid truncation methodology for the solution of Laplace's equation in open regions. The proposed method eliminates the need for approximate local boundary conditions the truncation boundary of the numerical grid. Thus, it provides for a simple, robust, computationally efficient and very accurate grid truncation scheme. First, an analytic justification of the proposed grid truncation methodology is presented. Next, its numerical implementation is discussed in conjunction with the numerical solution of Laplace's equation in unbounded two-dimensional regions. Numerical studies are used to illustrate the choice of the parameters used in the numerical implementation of this new truncation scheme, and quantify their impact on solution accuracy. A separable boundary value problem is used to motivate the proposed truncation scheme. The numerical studies and associated numerical results emphasize the calculation of per-unit-length capacitances for two-dimensional conductor configurations of the type used for unshielded planar transmission lines. |

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.
