【 摘 要 】

This objective of this research was to present a discretization scheme more efficient than the traditional central difference scheme, called Flux-Spline, in order to simulate tridimensional problems governed by diffusion. The efficiency of the proposed scheme was evaluated by means of the resolution of two test problems with a known analytical solution. The results showed a discretization scheme with adequate characteristics of accuracy that is, therefore, a recommendable option for the solution of tridimensional diffusive problems.
