Greetings,

Somewhat new to ANSYS and I am trying to model the collapsing/constricting of a blood vessel and how it affects blood flow. Ideally, I'd like to have the vessel begin constricting at a point in time that I dictate so it can be viewed in "real time" during animation. Does anyone have any experience with dynamic geometry during simulation or is that even a thing in ANSYS? I was thinking about adding a circumferential (hoop) stress to achieve the deformation but thought that might be a little too taxing computationally and didn't know if there was a way that I could just make the cross sectional area change wrt time.

Any help is VERY appreciated!
