TEC_TO_FEM
Convert a TEC Graphics File to an FEM Model

TEC_TO_FEM is a MATLAB program which reads a TEC graphics file containing a finite element model, and writes the information to three files in the FEM format.

The FEM files created will include:

• 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";

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

Usage:

tec_to_fem ( 'prefix' )

• 'prefix'.dat, is the name of the input TECPLOT file;
• 'prefix'_nodes.txt is the name of the output FEM node file;
• 'prefix'_elements.txt is the name of the output FEM element file;
• 'prefix'_values.txt is the name of the output FEM value file;
