tec_io, an Octave code which reads or writes a tecplot() TEC graphics file containing a finite element model.
There are several kinds of TEC 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
The data to be written or read is assumed to have a logical organization into three groups:
