tec_io

tec_io, a Fortran90 code which reads or writes a TECPLOT ASCII file containing a finite element model.

There are several kinds of TECPLOT ASCII files; the routines given here can only handle the case where a single ZONE record is used to define finite element data, using a DATAPACKING value of "POINT" (not "BLOCK"), and a ZONETYPE of

• FETRIANGLE
• FEQUADRILATERAL
• FETETRAHEDRON
• FEBRICK

The data to be written or read is assumed to have a logical organization into three groups:

• Node coordinate data;
• Element definitions, that is, the sequence of node indices that define each element;
• Node data, such as finite element coefficients for pressure, velocity, and so on.

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