Dear all:
I use 'fix roch all move/mesh mesh ch rotate/variable origin 0 0 0.6 axis 0 0 1 period 6.28' in in.simulation file in order to rotate 'ch' around the z axis under certain angular velocity.
But I get a error
ERROR: Variable name 1 for fix move/mesh rotate dynamic does not exist (mesh_mover.cpp:328)
How to solve the problem?
My LIGGGHTS is 2.1.X.

if I use 'rotate' instead of
if I use 'rotate' instead of 'rotate/variable', it seem that the period variable means the time period for rotate every 360 degree (2*PI). So, I also can use 'rotate' style to set the angular velocity?
period x in 'rotate' style in same as the period 2*PI/x in 'rotate/variable' style
Am I right?

Hello xujiancqu.If you have
Hello xujiancqu.
If you have a rotation with a constant angularvelocity you take "fix move/mesh rotate" to set the periode. This means the time one rotation takes for 360 degree (2*pi).
The "fix move/mesh rotate/variable" is used for simulations where the angular velocity changes during this simulation.
I hope this helps you.
Greetings
Niels
