Dear all,
For one simulation body, I set its properties via fix as follows:
fix 1 body rigid single
fix 2 body setforce 0 0 0
Then I set the body’s velocity via command: velocity body set 2 0 0. I dump the body’s velocity during simulation, and I found that the x-velocity is indeed 2, however, the y- and z-velocity is not zero. Why this happened? Will anyone tell me how to make the y- and z-velocity keep zero during the simulation? Thanks
