Hello,


I have just installed SU2 version 8.0.1 "Harrier" using a youtube video( https://www.youtube.com/watch?v=ac7lGG4V8I8 ). But as explained in the video there were not "./configure" step or "make" steps. So i have continued to the test the NACA tutorial and i have this error as shown in the attached picture.
Can someone tell this is becasue of an installation error or something else.


Thank you for your time.

This is a very typical MPI error; I used to encounter this issue frequently. Since I am quite familiar with SU2, I now use single-core computations (although not very efficient, it's sufficient for learning SU2). Therefore, I suggest you use single-core calculations as well.

If you must use parallel computing, please ensure that all necessary programs are installed.

Based on your information, the parallel execution command should not be like the one you used. Instead, it should be something like the following:

mpirun -n code_number SU2_CFD xxx.cfg

Please ensure you use the correct command format.

Hi Tongtong,

Thank you very much for the reply.
That error occurred when I tried to run the simulation using a single core but the simulation works when I run the case using parallel method.
Since I always run my simulations using parallel, I didn’t worry about running the simulation using single core, so didn’t bother to solve this issue.

Best regards,

I'm glad the issue is resolved ^^
