FIDAG, A Program for Finite Difference Interpolation on an Arbitrary Grid.
Abstract
This report documents the computer program FIDAG for performing finite difference analysis on arbitrary two-dimensional grids. Besides the detailed descriptions of the mathematical, numerical and implementation considerations for FIDAG, practical considerations for its utilization are discussed. Specific applications for the solution of partial differential equations and bivariate interpolation are treated along with sample numerical results. A simple data base system for convenient interface with engineering analysis programs such as STAGS (Structural Analysis of General Shells) is also discussed. These programs have been interfaced and sample results from the STAGS-FIDAG combination are presented.
