Blood Vessel Project Description
In this project, which has been done by Ansys Fluent software, a blood vessel is simulated with a wall, where the displacement of the wall is also visible. We have defined the pulse velocity using UDF for the input, and the output is atmospheric pressure. This FSI simulation was performed inside the fluent.
Geometry & Mesh
The three-dimensional geometry of this project has been produced with Spaceclaim software The length of the calculation domain is 72 mm, and its height and width are 5 mm.

Results
After the simulation, we can observe the velocity and pressure contours inside the vessel, and we can also examine the stresses and displacements created in the vessel wall due to the force exerted by the blood.
