Superposition of multiple fix move/mesh commands

Submitted by mali28 on Thu, 12/17/2015 - 10:26

I want to rotate a cylinder on its own axis at 3000 rpm as well as the origin (0,0) at 200 rpm. I am using move/mesh for this purpose. I am only able to rotate either on the local origin or on (0,0). I am unable to specify two rotations at the same time. Please let me know how to do this as in the manual it says it is possible to specify two rotations on a mesh. I would grately appreciate any help.

The code I am using is:
fix movecad all move/mesh/gran rotate 0.0 0.0 0.0 0.0 0.0 1.0 0.03 cad1

Please see the attached image. Later on I will also be adding corresponding centrifugal force exerted on the particles which are at the surface of the wall due to rotation of the cylinder over the particles. I will appreciate any suggestions on how that can be done.

Thank you.

Hi,

you just need to place a second fix move/mesh command after the first one.

best wishes
