[lammps-users] how can i fix the orientation of ellipse

Dear all,
Many thanks for all the helps from the mail list about “fix ellipse”.

But whatever “Fix freeze” “fix setforce” with zero velocity all give me a fix on the center of the ellipse. How can I just fix the orientation of the ellipse? Is it the angular velocity?

Fix freeze zeros out both the force and torque on a particle.
So it will fix the orientation. If you don't want it to fix
the force (just the orientation), you'd need to modify it
by taking out the lines that zero the force.
