Transient Simulation. Is antialiasing of the results possible?
 
Dear all,

I'm running a moving mesh simulation a sphere and having trouble setup & postprocessing the results.

With a fine timestep, the results are as shown in the figure below. The red line shows the drag acting on the body. When it moves, there's high fluctuation in the forces and i can't validated the data.

When i tried reducing the timestep or time interval of the data written, the following occurs where much of the force is not capture/reported accurately.

I'm thinking ANSYS might a feature to smooth out the fluctuations in post processor or antialiasing? but i have not come across it yet

Any help or suggestions would be much appreciated
