How to get the profile post processing done in SU2 and Paraview?
 

https://su2code.github.io/tutorials/Laminar_Flat_Plate/

At the end of this tutorial, there is a value profile comparison with Blasius Solution, I am wondering how to get the data from SU2, and how to process it in paraview? Can anybody give a hint? Thank you very much!

Hello,

I do not use Paraview so I cannot help you with that. However, I prefer to use VisIt which is an open source software. You can set your .cfg file to get outputs in the Tecplot format. Then VisIt can be used. For example in the link you provided, the is non-dimensional velocity, defined as . You can derive the corresponding expressions from the output files of SU2.

Hi David,

If you want to quickly plot the skin friction coefficient in ParaView, you can open the “surface_flow.vtk” file then use filters->Alphabetical->Plot Data->Apply. Then just leave the skin friction coefficient magnitude box checked. For the velocity profile, you can use the calculator to define your own variables based on others output by SU2. You can then plot the velocity profile by changing the x and y-axes parameters to the self-defined values from the calculator. If you are wanting to compare the results to the Blasius solution yourself, it would probably just be easiest to import the results from SU2 into something like MATLAB or Excel and manipulate and compare the data there.

Hope this helps,
Alex
