I have seen in other discussion pages that they can do it extracting the block or selecting the surfaces of the airfoil. However, in my VTK file I do not have those. I only have the fluid domain around the airfoil. Does anyone know how to extract the pressure distribution around an airfoil with the domain file I am attaching below?
Thank you in advance.

You need to share the associated files : domain*.vti
Thank you Mathieu. However, the software I am using to perform the simulation (called PALABOS) only generates .vtm files in this example. Is there something that I could do with the .vtm files?
alongside your .vtm file, there is a folder named domain_00000080, share it please.
please share an archive containing all your files together for simple access, thanks.
Sorry, I will compress it.
The file is too large so I uploaded it here.
So, you dataset indeed contains only the fluid domain. To extract the pressure at the airfoil you would need to share the airfoil geometry as well.
Thank you! I followed your steps and I got the same! However, what I was actually looking for was: how could I extract those pressure values to generate a 2D Cp vs X/c distribution?. Is there any option inside Paraview to get those values (as well as their position in x)?
Thank you again Mathieu!
Please precise what your are trying to achieve.
Hi @Victor - regarding the 2D Cp vs X/c distribution once you have your pressure applied to the geometry, did you try the “Plot On Intersection Curves”? (Filters -> Alphabetical -> Plot On Intersection Curves)
Judging from the screenshot above, you could set the plane to Z Normal and select your z-slice locations. I think by default, it will try to plot everything so you can untick all the series you don’t want. You’ll also need to set the x-axis X Array Name to Points_X.
Hope that helps a bit!
