TEC_TO_UCD
Convert TECPLOT ASCII Finite Element Data to AVS UCD Format

TEC_TO_UCD is a FORTRAN90 library which reads a TECPLOT ASCII file containing finite element data, and writes an equivalent AVS UCD (Unstructured Cell Data) file.

The TECPLOT home page describes the TECPLOT graphics program.

Usage:

tec_to_ucd file.dat file.ucd

reads the data from file.dat and writes it to file.ucd.
