Thank you for the further explanation.
I was confused with the meaning of the 'moving wall' feature. I guess, I expected similar results to the 'moving domain' feature implemented in Fluent, where one can expect to see the how the flow changes due to bluff-body motion on e.g. a velocity magnitude contour plot.
Now it is clear, that this 'moving' wall feature of AIM is a very-very basic version of that Fluent's feature. I regret to aknowledge it.
Can you please briefly explain how this phenomena, i.e. the moving wall, is handked within the solver? I guess that the additional pressure due to the quasi-motion of the wall (1/2*rho*U^2) is added/subtracted to the Steady/Transient results beside the wall?...
As I started in my original question, my goal with this 'moving wall' feature is to somehow get realistic forces (i.e. pressure distribution) to my bluff-body, so that I can further assess the aeroelastic behaviour of my structure. When I approach this with a Transient run (with the 'moving wall' feature is 'ON') I need the instantaneous forces/moments exerted on the body. Since unfortunately the 'moment reaction' is not yet available in AIM for fluid, neither I can send each CFD step result to the structural solver in the implemented FSI, that's why I need a lot of post-processing (Excel, Matlab) to extract the Moment Reaction. For that a 'Line chart' representing the pressure forces would be a conveniant tool, but unfortunately the implementation for this within AIM doesn't make any sense at all for Transient runs, because still only the Line Chart of the last step can be exported!
And this will bring us again to my other question that is still unanswered from ANSYS's side: https://forum.ansys.com/forums/topic/line-chart-result-discontinues-dashed
