Moving mesh translation + rotation

Dear friends,
Could some body please let me know how can I apply rotation and translation (at the same time) to a moving mesh imported from a stl file. Any response will be truly appreciated.
Regards,
Carlos

rotation+translation

Hi Carlos,
you could try applying same fix twice one with linear args and other with rotate args.

rotation + translation

Hi,

i tried to apply the same fix twice:

...
fix movescrew all move/mesh/gran rotate 0. 0. 0. 1. 0. 0. 0.3 screw 1
fix movescrew all move/mesh/gran linear 0.2 0. 0. screw 1
...

but that doesn't work. Only the linear movement is performed.

Cheers,
Klaus

That's correct - in the

That's correct - in the current implementation you can not superpose those motions, i.e. you would have to extend fix move/mesh/gran to do this.
