FEM_TO_TEC is a MATLAB program which reads three files defining a finite element model (FEM format) and writes a TECPLOT ASCII file suitable for display by TECPLOT.
The finite element model is assumed to include three items:
A naming convention assumes that these files share a common prefix, followed by the suffixes "_nodes.txt", "_elements.txt", and "_values.txt". Thus, the "carlos" set of data would be contained in the files "carlos_nodes.txt", "carlos_elements.txt" and "carlos_values.txt".
FEM_TO_TEC reads these three files and writes an equivalent ASCII ".dat" file that can be processed by the TECPLOT graphics program.
The TECPLOT home page contains a description of the TECPLOT program.

FEM_TO_TEC is available in a FORTRAN90 version and a MATLAB version.
FD_TO_TEC, a MATLAB program which converts FD models into TECPLOT ASCII files.
FEM_IO, a MATLAB library which reads or writes an FEM model.
FEM_TO_GMSH, a MATLAB program which reads FEM files definining a 1D, 2D or 3D mesh, namely a file of node coordinates and a file of elements defined by node indices, and creates a Gmsh mesh file.
FEM_TO_MEDIT, a MATLAB program which reads a pair of FEM files defining node coordinates and elements, and creates a corresponding MEDIT mesh file.
FEM_TO_TRIANGLE, a MATLAB program which reads FEM files defining a 2D mesh of triangles, namely a file of node coordinates and a file of elements defined by node indices, and creates a corresponding pair of node and element files for use by Jonathan Shewchuk's triangle program.
FEM2D, a data directory which contains examples of 2D FEM files, text files that describe a 2D finite element geometry and associated nodal values;
TEC, a data directory which contains a description and examples of TECPLOT ASCII graphics files.
TEC_IO, a MATLAB library which reads and writes TECPLOT ASCII graphics files.
TEC_TO_FEM, a MATLAB program which can convert a TECPLOT ASCII graphics file into an FEM model.
ELL is an example of a 2D finite element model in which a scalar value is stored. This data was computed by the FREE_FEM_POISSON program.
TINY is a "tiny" example of a 2D finite element model in which a vector value is stored.
