Elementary Introduction to Finite Difference Equations.

摘要

An elementary description is given of the basic vocabulary and concepts associated with finite difference modeling. The material discussed is biased toward the types of large computer programs used at the Lawrence Livermore Laboratory. Particular attention is focused on truncation error and how it can be affected by zoning patterns. The principle of convergence is discussed,and convergence as a tool for improving calculational accuracy and efficiency is emphasized. (ERA citation 01:025063)
