You can set particle velocities to whatever value.
You can also set selectively velocities according to different rules based on different regions/groups of particles.
> Do you have any ideas to remove kinetic energy/ reduce velocity of
you can remove kinetic energy by:
- reducing mass
- reducing velocity
as discussed above, you can set velocities to whatever values.
Since you want to preserve interactions, i.e. you want no running, I see no other option than modifying state.vel
