Particles orientations

Asked by Chiara Modenese

Hi there,

is there a way to store in the code the initial orientation of the particles and to call this (non-updated) value later inside the contact law and/or ScGeom?

Thanks!
Chiara

is only used for displacement scaling in post-processing currently. Use
it as you wish, it will be harmless.

 OK, will try it. Do you think it could also be easily initialized in a
random manner, say during as particles are generated? I would need to
generate particles with initial random orientation (as a reference).

You can probably initialize with random values, yes.

Thanks Chareyre, that solved my question.
