Uses the VTK library to convert unstructured data in .vtu files to regular gridded data.
For more efficient libraries useful for the huge datasets we suggest using Anaconda/Miniconda Python. Install / update by first doing from the Conda terminal environment:
conda update conda
conda install vtk numpy scipy h5py matplotlib
Install this (and prerequisite Python modules) in development "live" mode by:
pip install -e ./vtu2regular
python -m vtu2regular ~/my.vtu ~/out/my.h5
