Glad you got it working, would be nice to know what you fixed.
Also a comment, you should not need to run sudo to execute SU2

Thank you for a comment, yes I know, It is just a habit.:)

As you know building the SU2_DDC needs metis, So I have two version of metis in my system, metis-5.0.3 installed in my root and metis-4.0.3 in my trunk. When I was trying to build the code with metis-5.0.3, I got that error. I used mpicxx first and then change it to mpicc and then mpirun and nothing has been changed,So that is irrelevant to my compiler, Thus I compiled metis-4 first and then configure the code with metis-4.0.3 header and libs without cgns lib, moreover I used SU2_v2.0.1 instead of SU2_v2 and it is working great now, but still I cannot understand something, why every time that I reboot my system I have to export environment variable for SU2_RUN, Otherwise I got an error about couldn't find SU2_RUN.

I would like to thank you for your great work, It would be a great honor to use your code for my research work.

great, yeah metis 5 operates a bit differently from 4. glad you got it working

you can edit your bashrc file (~/.bashrc) to export SU2_RUN everytime you boot up.

best,
