[ESPResSo-users] Help Active system

Hello all!

I want to work on a active system. I understood I need "ENGINE" feature on in the myconfig.hpp file for particle to swim. However do I need the "ROTATION" and "ROTATIONAL INERTIA" features as well in myconfig.hpp?

What does the "ROTATIONAL INERTIA" do? In a Active Matter tutorial by Joost de Graaf and Henri Menke I found it has been suggested to activate this also. What if I have just "ENGINE"and "ROTATION" features on and not "ROTATIONAL INERTIA" for a value of v_swim=10. Does it somehow affects the physics?

Or "ROTATIONAL INERTIA" is just required if one wants anisotropic rotational diffusion?
