Dear All,

I am modelling the non-Newtonian blood flow in human arteries using Ansys Fluent. I used the carreau non-Newtonian model, however, I can't plot the viscosity contour in CFD Post.

Does anyone how to plot the non-viscosity contour in CFD post?

Kind regards,
AshtonJ

Hi, maybe you've already find your solution.
However, i'm going to suggest a solution that fit my problem. I hope it can be useful for you.
When your solution has stopped:
1. click on "Graphics and Animations"
2. under Graphics select Contours then click "Set Up"
3. Contours of "Properties" then select "Molecular Viscosity"
4. change levels as you prefer then "compute" and "display"

In my problem i have an UDF defining temperature dependent dynamic viscosity.
Looking to this contour plot i finded out that temperature field and dynamic viscosity field match.

I have the same problem... When I was using CFX I could calculate dynamic viscosity using this expression:

ave(Dynamic Viscosity)@Fluido

However, Now I am using Fluent to solve the same problem ( Natural convection in square cavity) and I cannot find the Dynamic Viscosity or even specific heat (cp) in CFD post... I know that I can find them in fluent results, but I want them in CFD post to calculate the rayleigh and Nusselt numbers...


Someone could help me?

Thanks a lot

I found it...



Go to "Run Calculation", select "Data File Quantities" and then select what you need. Then run the simulation again... There are a lot of other properties there that you can select....
