I want to simulate the blood flow in aorta or artery with SU2. I want to know the blood velocity, pressure on wall, wall shear stress. Is there any similar example?

Any suggestion is appreciated~~~

This is information that you either need to obtain from the specialized literature or from your own simulation results.

If the wall shear stress is ignore, is there any example which is similar with 3D blood flow?

[bigfootedrockmidget]

The closest example is probably the laminar flow in a bend. Have you already tried that example?
Do you already have the geometry or the mesh that you want to use for the simulations?

Do you mean TestCases/incomp_navierstokes/bend? Yes, I can successfully run it.

However, I don't know how to open the mesh_bend_coarse.cgns.

1. If I open it with notepad++, it shows some unreadable code.
2. If I load it with meshio, using meshio.read('mesh_bend_coarse.cgns'), it reports a bug:

File "h5py\_objects.pyx", line 54, in h5py._objects.with_phil.wrapper
File "h5py\_objects.pyx", line 55, in h5py._objects.with_phil.wrapper
File "h5py\h5f.pyx", line 106, in h5py.h5f.open
OSError: Unable to open file (file signature not found)

Is TestCases/incomp_navierstokes/bend a two dimension example?

There is a search engine called google that can help you look up information on the internet. Maybe you are in a region in the world where this search engine is less well known, but it is an invaluable tool to get information like this. Maybe you can ask somebody who is familiar with it to help you get introduced to it. You can then search for information using individual words or even sentences. You could search for instance for "cgns file format", "visualize cgns file", or "cgns reader python".



You can access it here: https://www.google.com/


If you can run the case, you should be able to visualize the results in paraview. You can also load the cgns file in paraview directly.
If you do not have paraview yet, you can for instance use google to search for "download paraview"

I apologize for this simple question. Actually, I have google the "cgns file format", and meshio is recommanded, but I cannot load it with meshio. I apologize for this simple question again.

[bigfootedrockmidget]

Try loading the cgns in paraview, or load the mesh in su2, run a simulation and save the result as a paraview (vtu) file.

Thanks for the suggestion, and I will try it.
