This is a collection of python tools I made for running and analyzing simulations using Mumax3. It's not intended as a general use package, though it does have a number of utilities that would be useful to anyone running micromagnetic simulations.

cd mx3tools
pip install .

If you want to install mx3tools so that the source is editable, use pip install -e ..

Load a set of simulation files from simulation.out/*.ovf into a numpy array:

from mx3tools import ovftools
data = ovftools.group_unpack('simulation.out/')

The data will be loaded into an array of shape (n_files, nz, ny, nx, 3), where n_files is the number of .ovf files in the directory, nz, ny, and nx are the number of simulation cells along z, y, and x. The last dimension holds the orientation of the magnetization as a vector, [mx, my, mz].
