Re: Visualize dipole moments

[Jean-Noël Grad]

Hello!

If all particles are magnetic and have the same dipole moment magnitude, 
you can pass option `director_arrows=True` to the openGLLive visualizer. 
In ESPResSo, the particle director is always co-aligned with the dipole 
moment. A minimal example is attached.

If you have different dipole moment magnitudes and would like to see 
this reflected in the length of the arrows, you will need to adapt the 
code in `src/python/espressomd/visualization.py` to draw dipole moment 
vectors. As a quick workaround, you can replace `particle_data.director` 
by `particle_data.dip` to change the behavior of `director_arrows=True`.

Best,
JN
