Numerical simulation of a stenosis

Goal: Perform a numerical simulation to mimic your mock loop experiment

and analyze the pressure distribution within the stenosis model

1. Create a 1:1 3D 50% stenosis in Comsol or Solidworks using the CAD

drawing provided in CANVAS.

a) Skip the holes for pressure tap and use the cut-point tool to detect

the pressure in those regions.

b) Ask yourself: If we need to simulate the fluid, which portion of the

drawing should we use to create the 3D model?

2. Perform a Comsol simulation for 1LPM and 3LPM pulsatile flow as input.

3. Determine what should be the output boundary condition? In your

experiment, the outlet is open to air.

4. Do you need entrance length?

5. What is the material?
