Greetings everyone,

I am not new to Paraview, but I also do not consider myself an expert. I have been trying to create a movie using ParaView. I made simulations in Fluent and exported the results to ParaView. The grid size is 8 million cells and it is an unsteady flow.
I was able to successfully export the results I wanted to ParaView and visualize them. However, I suffered from some issues. ParaView is very slow when visualizing the results or even importing them. I tried running it on a computer with excellent specifications, but the problem is still there.
The PC I am using has a core i7 processor with 8 logical cores, 64 GB RAM, and a 4 GB dedicated NVIDIA GeForce graphics card.
After visualizing the results, I am able to rotate the view and save an image without issues, but that's not the only thing I need.

I am trying to create a movie of iso-surfaces of Q-criterion at different time instants, and it appeared to be impossible and I don't know where the issue lies. I remember a professor showing us in the class a movie of 3D Lambda2 iso-surfaces that show the transition from laminar to turbulent and it ran smoothly without issues (it was OpenFOAM and the grid size was probably slightly smaller). Nevertheless, the movie he showed us was on his personal laptop, which has specifications by far less than the machine I am using.

Can anyone help?
Thanks.
