/tmp/tmpHNH55t/src.linux-x86_64-2.6/fortranobject.h:7:20: error: Python.h: No such file or directory

Writing VTK file using Python

To write VTK file using Python, download pytvtk. You can read the examples folder to get to know how to use it.

For example to write a structured points of scalar data stored in variable named Coef, we write:

PointData(Scalars(ravel(Coef,order='F'),'my scalar')))

this will save to a file name myfile.vtk
