fem_to_tec

fem_to_tec, an Octave code which reads three files defining a finite element model (FEM format) and writes a TECPLOT ASCII file suitable for display by TECPLOT.

The finite element model is assumed to include three items:

• Node coordinates, stored in a "node file";
• Elements defined by a sequence of node indices, store in an "element file";
• Node value data, such as finite element coefficients for pressure, velocity, and so on, stored in a "value file";

A naming convention assumes that these files share a common prefix, followed by the suffixes "_nodes.txt", "_elements.txt", and "_values.txt". Thus, the "carlos" set of data would be contained in the files "carlos_nodes.txt", "carlos_elements.txt" and "carlos_values.txt".

The code reads these three files and writes an equivalent ASCII ".dat" file that can be processed by the TECPLOT graphics program.

The TECPLOT home page contains a description of the TECPLOT program.

Usage:

fem_to_tec ( 'prefix' )

• 'prefix' is the common file prefix;
