A method to construct grid approximations for singularly perturbed boundary value problems for elliptic and parabolic equations, whose solutions contain a parabolic boundary layer, is considered. The grid approximations are based on the fitted operator method. Finite difference schemes, finite eleme

A finite-difference procedure which requires the use of ¨irtual and duplicate nodes is presented. This procedure incorporates the Neumann and Dirichlet boundary conditions into the two-dimensional Helmholtz equation. Comparisons made with analytic solutions for wa¨eguide modes indicate that robust s
## Abstract This work deals with the construction of difference schemes for the numerical solution of singularly perturbed boundary value problems, which appear while solving heat transfer equations with spherical symmetry. The projective version of integral interpolation (PVIIM) method is used. De
