Convert TECPLOT Finite Element Files to FEM Format

TEC_TO_FEM is a FORTRAN90 program which reads a TECPLOT file defining a finite element dataset, and writes a corresponding set of FEM files.


tec_to_fem file.dat
reads the TECPLOT ASCII file file.dat and creates the FEM files file.node_coord.txt, file.element.txt and file.node_data.txt.
