Applying Time Windows to Static simulation

Hello,
I have been trying to apply the Time Window to the car aerodynamics in a tunnel, however, I have been experiencing wrong output. I assumed maybe because of the wrong setup of the geometries or boundaries.

I was wondering if you have another example of using time windows used in Moving Time Window: Taylor Green Vortex Decay - NVIDIA Docs
lets say Aneurysm where we can see the blood flow ? that would be tremendously helpful since the Aneurysm has multiple geometries and correct setup. STL Geometry: Blood Flow in Intracranial Aneurysm - NVIDIA Docs
looking forward to your reply
