I'm studying blood flow in a cerebral aneurysm. I wish to run a parametrisation of the model by which i can make a mathematical expression between blood velocity and shear stress and the solver can change the geometry according to the output shear. Could someone show me how this is done.

Wall shear stress can easily be calculated by Fluent, but changing meshes depending of solution variables is really cumbersome with Fluent. However, with UDF programming it is possible in principle.

We have considered the movement of a vessel:

But for your problem I guess that you have to prescribe the movement of surfaces, take a look here:
