fluidsht 0.0.4a0

Getting started

For a basic installation it should be sufficient to run:

pip install fluidsht [--user]

You can get the source code from Bitbucket or from the Python Package Index. The development mode is often useful if you intend to modify fluidsht. From the root directory:

pip install -e .

Tests

From the root directory:

make tests

Or, from the root directory or any of the “test” directories:

python -m unittest discover

How does it work?

For the uninitiated, SHT is the spherical coordinates equivalent of FFT for cartesian coordinates. The aim of this package is to provides Python wrapper classes to facilitate SHT and related operators, very similar to FluidFFT, using various libraries such as:

• SHTns

• SHTOOLS

• libsharp

SHTns and SHTOOLS are an OpenMP implementations while, libsharp is an MPI implementation. All the libraries have built-in python bindings and SHTOOLS is pip installable. There are other SHT codes such as:

• HEALPix / Healpy

• Rayleigh

• S2HAT

which may be pursued if needed.
