Unhappy How to create velocity profile for falling ball in fluent CFD post processing

Hi,

I am trying to calculate terminal velocity for a ball(sphere) when dropped into a tank full of water.

I am using 3ddp, pressure based, dynamic mesh(smoothing and remeshing), laminar, transient solver.

After running the simulation, I am unable to plot the velocity profile of the sphere during its motion w.r.t its Y position. (ie velocity variable along y-axis and its location in y along x-axis).

I would be highly obliged if anyone could help me in plotting this graph.

Thanks.

Hello valr,

I would recomend you to create a different report in calculation activities. I am studing a similar setup and what I do is ask for an ASCI file with the X, Y coordinates and X,Y velocities (in your case could be differents since mine is 2D) of the body for each time step.

After that I use python to represent the motion and velocity of the center of gravity. You can use the software of your choice.

I haven't tried to plot this variables in the post porcessing tool.
