Python meshtal -> VTK converter.

Processes rectangular meshtallies. Output vtk files contain a rectilinear grid with cell values.

Only rectangular meshtally.

In case emesh is used to split into energy bins, the resulting vtk file contains values only from the total bin.

# Using the wrapper script:
>tovtk meshtal
# Using Python directly:
>pyhton -m tovtk meshtal

Get source from the github:

>mkdir tovtk-git
>cd tovtk-git
>git clone git@github.com:inr-kit/tovtk.git .

Use pip to install:

# with --user option does not require admin rights, 
# but PATH variable may need adjustments to point to 
# $HOME/.local/bin
>pip install --user -e .
# Or without the --user option. in this case requires admin rights
>sudo pip install -e .

If pip is not available in the system, it can be installed with the following commands:

# Download pip distribution, see https://pip.pypa.io/en/stable/installing/
>wget https://bootstrap.pypa.io/get-pip.py
# To install locally:
>python get-pip.py --user
# To install system-wide:
>sudo python get-pip.py

The local variant installs pip to $HOME/.local/bin. Ensure to add this folder to the $PATH variable.

The tovtk package uses the numpy package and Python bindings to VTK library. In a recent ubuntu they can be installed with

>sudo apt-get install python-numpy
>sudo apt-get install python-vtk

Alternatively, Anaconda includes numpy and vtk among many others.

The current version of Python 2.7 is shipped with pip, which can be used to install the precompiled numpy package.
