I am trying to install SU2 version 7.5.0 on Ubuntu 22.04.1 LTS and decided to compile from the code. I downloaded the source code, unzipped it, and I think I got all the dependencies installed (python, mpich, gcc, g++, etc). When I run:

$ .meson.py build

I get:

Downloading CoolProp '0ce42fcf3bb2c373512bc825a4f0c1973a78f307'
HTTP Error 404: Not Found
Download of module CoolProp failed.
Get archive at https://github.com/CoolProp/CoolProp.git/archive/0ce42fcf3bb2c373512bc825a4f0c1973a78f307.zip
and place it in the source code root folder
Run meson.py again

I went to https://github.com/CoolProp/CoolProp.git/ and downloaded the latest version from github, but now I'm struggling to find the appropriate folder to dump the *.zip. I've tried the folder above the SU2 source code folder, the top level SU2 source code folder, Common folder, and meson_scripts folder. Now it feels like I'm just stabbing in the dark.

Has anyone else run into this and successfully solved it?

I also tried downloading the pre-compiled Linux code of SU2, version 7.5.0 for parallel computations using MPICH. It runs fine in serial, but when I try to run parallel, I get however many "-n" jobs submitted in serial. For example, I tried submitting my job to 7 cores on my local machine via the following command:

$ parallel_computation.py -n 7 -f turb_ONERAM6.cfg

But that just launches 7 simulations, each on a single core. Using the mpirun command directly gives the same behavior. I've read about people having this behavior if the MPI is not recognized by SU2, but I installed MPICH prior to downloading the SU2 code, which seems to be the preferred MPI. Does anyone know how to configure the pre-compiled code to recognize the Ubuntu 22.04 MPICH installation?

You may try to download the *.zip from https://gitlab.com/coolprop/coolprop...78f307/include
and place it in the source code root folder

Thanks for the CoolProp link! It looks like it worked fine and compiled when I placed the *.zip file in the folder containing the meson.py file. The ./ninja command churned around for a while and came back without error, so I figure I got a compiled version of SU2 on my machine now. When I run which commands, this is what I get:

$ which SU2_CFD
/usr/local/bin/SU2_CFD
$ which parallel_computation.py
 /usr/local/bin/parallel_computation.py

So that looks successful! Thanks for the help!

I can successfully run the tutorial case in serial, but when I tried to run in parallel, I got the following error:

$ parallel_computation.py -n 8 -f turb_ONERAM6.cfg

Open MPI tried to fork a new process via the "execve" system call but
failed.  Open MPI checks many things before attempting to launch a
child process, but nothing is perfect. This error may be indicative
of another problem on the target host, or even something as silly as
having specified a directory for your application. Your job will now
abort.

Any idea where I start digging for clues on what might be going on with my installation of MPICH? It looks like I have MPICH installed as this is the output of the which command:

$ which mpirun
/usr/bin/mpirun

I still don't know entirely what is going on with my installation, but I did get the following to work well for me:

$ mpirun -n 8 SU2_CFD turb_ONERAM6.cfg

Notice the error "permission denied". This means either that you do not have read/write/execute permissions for one of the folders, or that the folder does not exist.
