Hi!
I have been using LIGGGHTS (v. 3.0?) some time ago and I was able to fix a mesh/surface/stress/servo, locate it properly in the simulation (rotate, move), then run some timesteps and then move it again, this time using move/mesh. So after all I had something like a plate compressing particles with constant pressure, which could later move tangentially to the servo direction, irrespective of the load in that direction. In the newest release I have installed (3.3.1), it says: "This fix can not be used in conjunction with another fix that manipulates mesh geometry, such as a fix move/mesh".
Why is it so? Is it going to be fixed? Is there any workaround?
Regards
