Hi! I've been trying to simulate transonic flow (0.8 Mach) over a naca0012 but havent been getting any reliable results. 
would the mesh that I've attached be able to simulate transonic flow well please? I found a picture of it, but there seems to be no tutorials on how to generate it sadly

thanks in advance!

Hi,

I recommend you to check the Ansys Innovation Course: Mesh — Lesson 4 - ANSYS Innovation Courses

Hope you find this useful.

Thank you

Mesh looks a little coarse on outer side. But it needs fine enough mesh near airfoil which is not clear from image. 

Please go through help manual for more details

Hello Saurabh and Keyur , thanks for the link but I’ve actually already tried it for a C-mesh.

Sorry I’m a bit confused about how to use it for the parabola mesh too? I don’t think  it would give similar meshing as to my picture as that lesson requires me to split up the domain into 4 too? Would this work?

What’s also making me confused is the mesh shape (far field), I don’t see how they generated it with that finer but just above and below the aerofoil? Could using ‘lines’ within the sketching of Andy’s fluent do this please?

 

also I found this close up in a paper, it looks like the use of inflation:

 

thanks in advance

Hi,

You can create it using ICEM CFD. There are various tutorial available in youtube regarding creation of mesh over airfoil using ICEM CFD.

Hope this will help you.

Thank you

Hi Saurabh, do you think this mesh could be made in Ansys Fluents design modeller please? I find icem a lot harder to use

 

thank you for trying to help
