Hi everyone,
I'm simulating a rotating drum and I want to compare the results I obtain using this three methods :
Imposing rotation by using fix move/mesh
imposing rotation by using fix mesh/surface surface_angle_vel
imposing a rotating gravity.
I' m obtaining similar results in both the first two cases in terms of kinetic energy and power draft but not in the last case!
To understand what's wrong, I'm trying to visualize data on paraview but I need to rotate the camera in order to make it coherent to the real case (otherwise, I'll just see particles sliding following the cylinder surface)
I've seen that the orbit camera in animation view of paraview can be used, but it's not possible to impose a specific angular velocity; beside that, when trying to rotate the camera around the axis of rotation, I don't obtain what I'm expecting ..
Does anyone know an external software that I can use to rotate the view dynamically? if yes, I could export the animation from paraview and then set the rotating view in that software.
Thank you!

I've found it!
I solved it using HitFilm Express! By rotating the point of view of the camera, the particles act like the cylinder was rotating.
Although the "shape" of the moving system looks the same, the problem is that if I compute the power draw as the product of angular speed and torque around the axis of rotation, the results obtained are:
- similar when comparing the rotation with fix move/mesh and fix mesh/surface surface_angle_vel
- really different when comparing one of the above results with the moving gravity case.
any hint?
