Cp and x/c for Turbulent NACA 0012

koala123 · October 27, 2021, 07:43

Hi everyone,

I am trying to replicate the results seen here

https://su2code.github.io/tutorials/...lent_NACA0012/

I have SU2 version 7.0.2. Installed, ran fine. I was able to view the pressure map on Paraview.

How do I get the Cp vs x/c plot though? I read the output format here

https://su2code.github.io/docs_v7/Custom-Output/

to say

OUTPUT_FILES= (RESTART, TECPLOT_ASCII, SURFACE_TECPLOT_ASCII)

Then reran the simulation, and now I have surface_flow.dat, and flow.dat, I can read the Pressure_Coefficient from this file, but what is it plotted against?

Thanks,

I always use PARAVIEW_MULTIBLOCK, which gives the boundaries as separate entities. You can then do an Extract Block to select only the naca profile wall boundary. You can then select the Plot Data filter to visualize only the data on the surface as a function of x-coordinate.
