tovtk

Python meshtal -> VTK converter.

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

Limitations

Only rectangular meshtally.

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

Invocation

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

Installation

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.

Dependensies

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.

Under windows

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