Maybe not all appreciate the time and effort it takes to do a good video like this one. Kind regards!

Thanks! It definitely took a little time to put it all together.

Hey Josh, I hope you see this. I have been coming to this video again and again for the last year because I absolutely love to use the oblique shock example as a validation of my own hypersonic CFD solvers. I can appreciate the amount of effort you have put into this video, and I'm thankful for it. Best regards ~stk

Thanks, I appreciate it! Yea, the oblique shock problem is a great test case. It's nice to have analytical solutions for comparison, and it's a nice stable problem for CFD solvers.

I knew you needed this back in 2017, so I made sure to wait until 2018 to post it so I could inconvenience you.

Great methodology and tutorial, thanks!

Buenas tardes desde España! Muchas gracias por el vídeo. Te quería preguntar, ¿qué tengo que implementar en el código para obtener las variables conservativas? En el archivo history.csv se ubican los RMS de rho, rho_U, etc. pero no lo valores de rho, rho_U. Gracias!

whenever i m trying to install and open SU2, it is showing that configuration file is missing. not able to open only. please help

Thanks for the video. Can you explain configuration file for structural mechanics and how to do a 3D analysis ?

You're welcome! I actually don't have any experience doing structural analysis or 3D simulations, so I won't be able to help you unfortunately.

Dear Josh, Thank you for uploading excellent video for new users of Gmesh and SU2. I followed all steps for generating the mesh with GMESH and mesh saved in .su2 format is of size 2.3mb, i.e. "Your_Mesh_Name.su2". Whereas the file you are using is of size 3.4mb, i.e. "Mesh_OS_Single". I can run the code successfully in SU2 with 3.4mb ("Mesh_OS_Single" downloaded from your website) file but not with 2.3mb file ("Your_Mesh_Name.su2").

In the tutorial, you have forgotten to add Geometry > physical group > add > surface

hi could you please make tutorial on how to run SU2 with MPI paralley

Excellent tutorial, very helpful.. Can you please share the MATLAB code used in this tutorial?

Thanks! And oh boy, I'd have to look through all my stuff to find it. I might try to finally upload my reflected shock video, and if I do, I'll be able to find the other code for this video.

Can this be done on windows 10?

One comment re the top boundary condition: you've made it a slip surface BC like the lower one but I'd like to see how to make a ore arbitrary BC that didn't depend on the fact that the shock exited the outlet boundary.

Hi, on my version of Gmsh I do not have "line" under physical groups. How do I name a line boundary? Any guidance will be much appreciated.

I figured out how to name my physical groups. I just user the "curve" option. However I am not stuck at the configuration file. Can anyone explain or link a video that can help. Do I have to customise my configuration file for each simulation I do or can I use the master code?

Hi, great video. Can you also post the Matlab file too?

Thanks! I'll post the MATLAB file after I make my reflected shock video. I've been really busy lately, but I'll have that video up soon-ish, and along with it, the code.

Mach number is relative or absolute?

@JoshTheEngineer

4 жыл бұрын

The Mach number is always based on the local quantities at that particular point. So in this case, the Mach number upstream of the oblique shock is a function of the upstream speed of sound and upstream velocity. The Mach number downstream of the oblique shock is a function of the downstream speed of sound and downstream velocity. Another way of saying it in words is that the Mach number is equal to the local velocity divided by the local speed of sound.

Has anyone the config file ? I haven't acces on the link

@JoshTheEngineer

Жыл бұрын

The link should work again since I've fixed the problem with my website. However, this config file is for an earlier version of SU2, so you might need to update it based on whatever version you're running.

I am getting vtu file instaed of vtk . can anyone tell me the reason why is it happening , because I can't load vtu file in paraview

@JoshTheEngineer

3 жыл бұрын

In the configuration file, find the "OUTPUT_FILES" variable, and instead of the default "PARAVIEW" entry, use "PARAVIEW_ASCII" instead. That should give your flow file the .vtk extension you're looking for.
