Question Boundary Conditions in Transient Structural Analysis

Dear All,

I simulated blood flow in a constricted artery with rigid walls.

At the constricted region, I defined a plane and plotted the fluid pressure distribution over the plane. I want to take the fluid pressure over the wall boundary (it is a circular line) of that plane and use this pressure distribution in structural analysis to see the effect of it on the wall deformation.

The image of the artery wall in the constriction region is attached in below link.

The pressure I got from the fluid part should be applied over the inner circle.
Please let me know how I can load the pressure into structural part.

For other boundaries, I don't have any idea what boundary conditions should be used (outer circle, the surfaces between the inner and the outer circles).

Does anyone have any idea about the boundary conditions.
Thank you.
