Convert .vtk files to .dat files for viewing in Tecplot

.vtk to .szplt convertor

This script can convert .vtk rectilinear grid files to .dat or .szplt files for viewing in Tecplot

Enabling Conversions .xdmf / .vtr / .vtk to Tecplot .dat / .tec / .plt / .szplt

Instructions

Working in Linux

1. Open Paraview readable formats in Paraview.

2. File>Save Data...>select format as legacy .vtk and ascii.

3. Keep .vtk file in the folder containing script.

4. Copy libtecio.so from Tecplot path/to/tecplot/installation/bin to tecio directory

5. Run script:

   for output as .szplt

   		python vtk2tecplot.py szplt 

   for output as .dat

   		python vtk2tecplot.py dat 

Dependencies

1. Numpy
2. TECIO.dll (included)
3. tecio_szl.py from github.com/Tecplot/handyscripts/tree/master/python/dataconversion/ (included)
4. libtecio.so or tecio.dll (not included)

Very limited testing done! Sucessfully converts a .vtk file generated by paraview from a 3d flow simulation snapshot to .dat and .szplt file readable by tecplot. May need modifications to work with 2D plots, different type of grid, etc.
