Is there any way I can print CFL value at each iteration on screen? I put AVG_CFL in SCREEN_OUTPUT but after some iterations its value becomes constant. I am not sure what does AVG_CFL actually giving? I saw it in one of the posts and tried it.



P.S.- I am new to SU2

Hi,

To check the options available for history/screen output, you can run SU2_CFD -d yourconfig.cfg. This should allow you peruse more options.

Regarding CFL....The AVG_CFL is the average CFL of your entire problem. You can also print the minimum or maximum local CFL (MIN_ or MAX_CFL) numbers. If you are using an adaptative CFL, the local values of CFL will change noticeably which is why you may see some changes. Hope this helps.

Thanks for your reply. It really helped. Also, can you please elaborate a bit more on MIN_ or MAX_CFL? like what they represent particularly what do we mean by locally term in that perspective?
