H. Giese and H. Khalil and D. L. Ulery}, journal={Journal of Engineering Mathematics}, year={1978}, volume={12}, pages={97-114} }

SummaryA symbolic technique is developed to automatically generate consistent multiparameter families of difference approximations to the heat equation with Dirichlet boundary conditions in arbitrary regions. A stencil of non-uniform step size, conformable along the spatial axes via spatial displacement parameters, is devised to handle the problem of irregular boundaries. Using this stencil as a basic building block, multiparameter families of difference schemes applicable without modification… Expand
