Two Files Describing a 2D Finite Difference Model

**FD2D**
is a data directory which
contains examples of 2D 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:

- Node coordinates in 2D;
- Node values (scalars, vectors, or any set of data);

- ASCII
- Each line is one "record"
- Each record is either a comment record or a data record;
- Comment records begin with the "#" character;
- A data record records node coordinates for one node, or the set of node data for one node;
- For a given file, each data record contains the same number of items, separated by blanks.

FD_TO_TEC, a MATLAB program which converts FD (finite difference) models into TECPLOT ASCII files.

FD1D, a data directory which contains examples of 1D 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;

**ELL** is an example of a 2D finite difference model
in which a scalar value is stored.

- ell_nodes.txt the nodal coordinates.
- ell_values.txt, the nodal values.
