how to specify "angular velocity" in "fix move" command?

Hello, there:

I am working on a simulation in which diamond is used to cut copper material,

now I want to rotate the cutting tool by a certain degree (pi/6), I found “fix move” might be able to do so, the command has six arguments (Px, Py, Pz, Rx, Ry, Rz, period), but based on these arguments, I am only able to define the rotation axis and rotation period, while not able to specify angular velocity, which is important to define the final location of my tool.

is there any way to define angular velocity for rotation in “fix move”?

thanks for your help in advance.

Hello Yachao,

I am assuming you are using ‘fix move rotate’ in which case the period will define the angular velocity omega given by

omega = 2 PI / period

Hope this helps.
