FEM_TO_TEC
Convert an FEM Model to a TECPLOT ASCII File


FEM_TO_TEC is a MATLAB program 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:

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".

FEM_TO_TEC 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' )
where reads the files 'prefix'_nodes.txt, 'prefix'_elements.txt and 'prefix'_values.txt and creates the TECPLOT ASCII file 'prefix'.dat.
