Hi all,
I feel like i'm losing my mind a little.
I wish to clone my model and make minor changes to the same physical assembly, but alter certain boundary conditions such as inlet / outlet pressure.
The problem that I am having is that I have 'cloned' a study (right clicking the project and cloning), and ran the study from new (remesh / new calculation) without changing any boundary conditions
Despite not changing any boundary conditions, i am witness vastly different results in terms of flow trajectories and surface plots...
My model is really quite basic, so i feel like I am doing something fundamentally wrong.
Any advice would be greatly appreciated.

Sorry all,
I found the solution.
I am using the rotating region feature - when i suppress this feature from both clones, results are identical.
I guess the new question is now, why does this happen? Why is the flow random for each simulation with rotating region enabled.
This is an internal flow simulation,
