Info

This page goes through the geometry steps for the 3D Bifurcating Artery - Exercises in the SpaceClaim geometry engine included with ANSYS Workbench. For instructions on creating the geometry using SolidWorks see the page 3D Bifurcating Artery - Exercises (Legacy).

  1. Create a new sketch, move to one end of the obstruction

  2. Use Spline to mimic the artery boundary (just click on the edge of the artery that is visible and follow the dots that show up)

  3. Use Offset Curve to create two more curves: one inside and one outside the artery

  4. Return to 3D mode

  5. Hide the artery

  6. Delete the inner portions of the resulting surfaces leaving only the outer ring

  7. Unhide the artery

  8. Do the same on the other end of the obstruction

  9. Hide the artery

  10. Use Blend and then control + click the two faces that remain

  11. Unhide the artery

  12. Ctrl + Click the missing ellipse and fillet and click Fill if you haven’t already

  13. Use Combine as before to create three solids

  14. Delete or suppress all entities except the artery

  15. Use pull to smooth any sharp edges as desired

Simulating the Non-Newtonian Fluid Using Casson Fluid Model

A user defined function (UDF) can be used to implement the Casson fluid model. The Casson fluid model is given below:
