Installing pypi version

If you have pip, you can simply do this:

pip install pyJHTDB

If you’re running unix (i.e. some MacOS or GNU/Linux variant), you will probably need to have a sudo in front of the pip command. If you don’t have pip on your system, it is quite easy to get it following the instructions at http://pip.readthedocs.org/en/latest/installing.html.

Installing from source

ubuntu 14.04

Bare-bone installation:

sudo apt-get install build-essential gfortran
sudo apt-get install python-setuptools
sudo apt-get install python-dev
sudo easy_install numpy
sudo python setup.py install

Note that doing this should, in principle, also install sympy on your system, since it’s used by pyJHTDB.

Happy fun installation:

sudo apt-get install build-essential gfortran
sudo apt-get install python-setuptools
sudo apt-get install python-dev
sudo apt-get install libpng-dev libfreetype6-dev
sudo apt-get install libhdf5-dev
sudo easy_install numpy
sudo easy_install h5py
sudo easy_install matplotlib
sudo python setup.py install

I haven’t tested the installation on any other system, but I think reasonable variations on the above should work for the minimal installation on all unix systems (i.e. for MacOS as well). If you manage to get it working (i.e. you import test_plain like the README says and you can run it), please let me know what steps you needed to take for your system, so I can append the instructions to this file.

Basic usage

Although this particular Python wrapper is still a work in progress, it is mature enough to be used in production work.

On first contact with this library, we recommend that you first run “test_plain”. To be more specific:

from pyJHTDB import test_plain
test_plain()

The code that is executed can be found in “pyJHTDB/test.py”, and it’s the simplest example of how to access the turbulence database.
