streamtracer is a python package for rapid streamline tracing. It is a wrapper to compiled fortran code that does the heavy lifting, and is therefore relatively fast.
To use, create a
nsteps = 10000 step_size = 0.1 tracer = StreamTracer(nsteps, step_size)
field = np.ones((10, 10, 10, 3)) grid_spacing = [1, 2, 1] grid = VectorGrid(field, grid_spacing)
This can then be used to trace lines through a 3D cartesian vector field:
seeds = np.array([[0, 0, 0], [0, 0, 1]]) streamlines = StreamTracer.trace(seeds, grid)
For more information see the
streamtracer API docs.
In theory, it should be possible to build and install streamtracer in one go with:
pip install streamtracer
Note that this requires a fortran compiler; currently known to work is gfortran. If you have problems installing, please open an issue at https://github.com/dstansby/streamtracer/issues
- Make sure to install numpy before trying to install streamtracer.
First streamtracer release.
