Numerical Solution

Watch the following video for demonstrations:

Summary for the video:

  1. Monitors → Create → Drag → Print to Console → wall_artery
  2. Solution Initialization → Hybrid Initialization → Initialize
  3. Calculation activities → Create → Solution Data Export → Change File Type to "CFD-Post Compatible"
    Quantities for export: Static Pressure, Total Pressure, Velocity Magnitude, x velocity, y velocity, z velocity, Wall Shear (* note that you need to export all three components of velocity in order to plot vector field in CFD-Post!)
  4. Create → Particle History Export → File Type to CFD-Post → Select the injections → Choose to save directory
  5. Run Calculation → Time Step Size 0.01 → Number of time steps 50 → Max Iterations/time step 200 → Hit "Calculate"!
If you are using ANSYS 19.2, refer to the steps below:
  1. Setup → Reference values → Type in the values given in the above table
  2. Report Monitors → New → Force Report → Drag → wall artery
  3. Solution Initialization → Hybrid Initialization → Initialize
  4. Calculation Activities → Create → Solution Data Export
  5. Change the file type to “CDAT for CFD Post and Ensight”
  6. Select above-mentioned quantities for export
  7. Calculation Activities → Create → Particle Data History Export → Select both injections
  8. Run Calculation → Time Step Size(s) 0.01 → Number of Time Steps 50 → Maximum Iterations/Time Step 200 → Hit Calculate

Before running the calculation, you should also create a monitor for the inlet velocity so that we can check that the UDF is working correctly in the Verification and Validation step.

  1. Report Monitors → New → Surface Report → Area-weighted Average
  2. Set Field Variable as Velocity → Velocity Magnitude
  3. Select "inlet" under Surfaces
  4. Make sure to check the box next to Report Plot
  5. Give it a suitable name and click OK
