[SU2_user]

I installed SU2 with the following commands on ubuntu 24.04:

sudo git clone https://github.com/su2code/su2.git
sudo apt update
sudo apt install mpich libmpich-dev
cd SU2
sudo ./meson.py build -Denable-openblas=true
sudo ./meson.py build -Dwith-mpi=true
sudo ./meson.py build -Denable-pywrapper=true
sudo ./meson.py build -Denable-directdiff=true
sudo ./meson.py build -Denable-autodiff=true
sudo ./ninja -C build install

I get the following message with each of the commands:

update CoolProp
/usr/bin/SU2/subprojects/CoolProp
/usr/bin/SU2
CoolProp updated
Directory already configured.

Just run your build command (e.g. ninja) and Meson will regenerate as necessary.
If ninja fails, run "ninja reconfigure" or "meson --reconfigure"
to force Meson to regenerate.

If build failures persist, run "meson setup --wipe" to rebuild from scratch
using the same options as passed when configuring the build.
To change option values, run "meson configure" instead.


When I tried following the quick start guide to run the discrete adjoint, I get the error saying SU2_CFD_AD: command not found. I did not find the SU2_CFD_AD executable or directory anywhere.

Here are my path variables:
export PYTHONPATH=/usr/bin/python3
export SU2_HOME=/usr/bin/SU2
export SU2_RUN=/usr/bin/SU2
export PATH=$SU2_RUN:$PATH
export PYTHONPATH=$SU2_RUN:$PYTHONPATH
export MPICC=/usr/bin/mpicc
export MPICXX=/usr/bin/mpicxx


Please let me know if I am missing something.
Thanks

sudo ./meson.py build -Denable-openblas=true
sudo ./meson.py build -Dwith-mpi=true
sudo ./meson.py build -Denable-pywrapper=true
sudo ./meson.py build -Denable-directdiff=true
sudo ./meson.py build -Denable-autodiff=true
sudo ./ninja -C build install

Do not sudo everything, every time you use su or sudo, be aware of what you are doing. Local actions should never be done with su rights. only the ninja install to a global directory should be done with sudo. But I recommend keeping it installed in your own directory (in bin or SU2/bin) using the --prefix argument unless you are the administrator of a network where more people need access to SU2.


In any case, you need to combine the meson arguments into one meson command because else the previous command will be overwritten. Also, you overwrite the previous meson command with the argument --reconfigure. If you do not provide that, the new meson command will not create a new configuration. So you need to do this:

./meson.py build -Denable-autodiff=true -Denable-pywrapper=true -Denable-directdiff=true -Dwith-mpi=enabled -Denable-openblas=true --prefix=~/bin

and if you already have a meson configuration:

./meson.py build --reconfigure -Denable-autodiff=true -Denable-pywrapper=true -Denable-directdiff=true -Dwith-mpi=enabled -Denable-openblas=true --prefix=~/bin
