Hello all,
fix move all move/mesh mesh cad1 rotate ... rotates the mesh along the axis specified.
for eg: motion similar to rotation of earth around the sun can be done using the above fix.
My question is: Is there any fix to define the motion similar to moon roationg around earth where it is tidally locked.
Perhaps you can understand better if you see the picture attached. I would like to get motion similar to the bottom half of the pictue.
cheers,
manton

The clue is to use
The clue is to use superposition of two rotate commands (one for the orbit and one for the body-coordinate-system):
variable omega1 equal 3.1415
variable omega2 equal -3.1415
fix rotcad1 all move/mesh mesh cad1 rotate/variable origin 0. 0. 1. axis 0. 1. 0. omega v_omega1 #rotate arround 0 0 1
fix rotcad2 all move/mesh mesh cad1 rotate/variable origin 0. 0. 0. axis 0. 1. 0. omega v_omega2 #rotate arround COM against rotcad1
#optional
#fix rotcad3 all move/mesh mesh cad1 rotate/variable origin 0. 0. 0. axis 0. 0. 1. omega v_omega1 #rotate arround COM z-axis
where cad 1 is located in 0/0/0 and rotates arround y-axis in an orbit with R=2 m
