I am having difficulties trying to simulate biaxial rotation of an imported mesh.
I am looking the simulate the motion which occurs during rotational moulding where the mould (mesh in this case) rotates around two of its axis.
The current rotation commands within LIGGGHTS that I've found allows rotation to be set to the coordinate system in space but not to the mesh itself, which is where my issue lies.
The primary axis of rotation (y-axis for example) can be set by using the coordinate system in space as this axis of rotation does not move during rotation. However, the secondary axis of rotation rotates with the primary axis and travels between the x and z axis (within the coordinate system in space) which I cannot achieve.
I hope what I'm writing makes sense to somebody as I'm at a lose how to achieve this rotation motion.
If it was possible to give the mesh its own coordinate system then it would solve my issue but I don't believe this is possible???
Anybody have any ideas on this?
Many thanks,
Jon
