A generalized finite-difference solution of parabolic 3-D problems on multi-connected regions
Abstract
A method for the solution of 3-D parabolic problems on multi-connected regions is presented. The domain discretization is automatic: at first the boundary is approximated by means of polyhedra; subsequently a Cartesian orthogonal non-uniform grid is generated. The differential operator is discretized by a Crank-Nicolson scheme, coupled with general finite-difference formulae (GFDF).
Some test problems are presented to show the efficiency of the method.
