A python script that reads plot3d unformatted file.

Require numpy and fortranfile:

pip install numpy
pip install fortranfile

Using:

python pyPlot3d.py  -plot3d  2-block.dat

Motivation:

I want to use python to generate 1-to-1 block interface (topology information) for my CFD code. So I spend some time to figure out how to read fortran unformatted file in Python.

Notice:

The array dimentions in this python script is not like in Fortran. For example:
Fortran: x(i,j,k)
Python: x[k,j,i]
So when using it, make sure you put i,j,k in the right place.
And by the way, in this python script, i,j,k data in the arrays are started from 1 as in Fortran. x[0,:,:], x[:,0,:] and x[:,:,0] are placeholders and have no meaning.
