FD1D is a data directory which contains examples of 1D FD files, which define a finite difference model.
The FD format is a simple dataset of two files that can be used to describe a finite difference model.
The finite difference model is assumed to include just two kinds of information:
The computer code and data files described and made available on this web page are distributed under the GNU LGPL license.
FD_TO_TEC, a MATLAB program which converts FD (finite difference) models into TECPLOT ASCII files.
FD1D_DISPLAY, a MATLAB program which reads a pair of files defining a 1D finite difference model, and plots the data.
FD2D, a data directory which contains examples of 2D FD files, two text files that can be used to describe many finite difference models;
FD3D, a data directory which contains examples of 3D FD files, two text files that can be used to describe many finite difference models;
ARCTAN contains sample data from the arctangent function at 29 non-uniformly spaced nodes.
FD1D_BVP_TEST01 contains the computed and exact solutions for a boundary value problem.
PAIR shows how a plot is made when there are two columns of data in the "values" file. The first column is a copy of the original ARCTAN data, and the second column is some perturbed values.
