Title: An Optimization Of The Finite Difference Method For Modeling Solidification Of Complex Shaped Domains
Author: Alvares Spim Jr. J.
Garcia A.
Abstract: The finite-difference method is widely used in the formulation of a mathematical representation of the solidification process in metal/mold systems. When complex geometries have to be analyzed, generally Finite-Elements Methods are preferred. The present work proposes a modification in the distribution of elements from the mesh, by using an analogy between electrical and thermal circuits, which permits greater versatility in discretizing regions of complex shape The governing equation of electrical circuits theory is used by applying an explicit version of the Finite-Difference Method.
