Apply motion equation to stl geometry.

Very new ParaView user here…

I have a DEM particle simulation of a screw auger where geometry is moving through time. Rather than export the screw stl at every timestep of the DEM simulation, I would like to just apply a motion to the screw geometry using an equation (ex: velocity = f(time)) or time-varying transform in ParaView. Ideally I import the particle data through time, the stl file at time =0, and nothing else.

Is there a relatively simple approach to doing this? Through the Calculator maybe?

PythonCalculator will provide time related variables, just hover the field for a second and the doc will appear.
