Hi im trying to run Inviscid ONERA M6 tutorial in parallel but after all iterations i get the following errors:
Error in "virtual void CBaselineOutput::SetVolumeOutputFields(CConfig*)":
-------------------------------------------------------------------------
No coordinates found in the restart file!!
------------------------------ Error Exit -------------------------------


Identify vertices.
Storing a mapping from global to local point index.

Reading and storing the solution from restart_flow.

mpirun detected that one or more processes exited with non-zero status, thus causing
the job to be terminated. The first process to do so was:

Process name: [[6296,1],1]
Exit code: 1
--------------------------------------------------------------------------------------
I tried running the same tutorial using serial, and i did not get any error. But i want to run it in parallel. Can somebody help me? I am actually new to SU2 and i don't know much about it.

Also, how can i check if my su2 is build for parallel support?

Does simply running mpirun directly work for you?



mpirun -n 4 SU2_CFD inv_ONERAM6.cfg

1. I installed anaconda by using this command
Code:
wget https://repo.anaconda.com/archive/Anaconda3-2023.07-2-Linux-x86_64.sh
2. Then i downloaded SU2-7.5.1.
3. Then i ran following commands one by one:

Code:
conda install cmake
conda install pkg-config
conda install gxx_linux-64
pip install mpi4py 
pip install swig
./meson.py build -Dcustom-mpi=true -Dextra-deps=mpich -Denable-autodiff=true
./ninja -C build install
Then i entered following in a new terminal
Code:
nano .bashrc
Then i pasted following lines to the end
Code:
export SU2_RUN=/usr/local/bin

export SU2_HOME=/home/mohsin/Downloads/SU2-7.5.1

export PATH=$PATH:$SU2_RUN

export PYTHONPATH=$PYTHONPATH:$SU2_RUN
I used following things
ubuntu 22.04 (on virtual box version 7.0.10)
anaconda3
python 3.11.4
SU2-7.5.1

Thats it.

Actually this is a very old post, at that time, my su2 was not compiled correctly for parallel. But its fixed now. Thank you so much.

Hello,

Could you tell me how to properly compile SU2 for parallel runs?

When I write "mpirun -n 4 SU2_CFD example.cfg" I see 4 times for eveything on console.

Regards.

Check that you have installed the development files, either libopenmpi-dev or libmpich-dev.

Also check that you have only one mpi installed to prevent conflicts.
