I am going through the step by step guide on setting up an aws cluster and install of openFoam (here)

When I submit the motor bike tutorial run that's included, the blockmesh and snappyhexmesh run correctly, however the simplefoam command does not run and i get the error "mpirun was unable to find the specified executable file"..... "Executable: simpleFoam" in the log file.

My submit file:

#!/bin/bash
#SBATCH --job-name=foam
#SBATCH --ntasks=288
#SBATCH --output=%x_%j.out
#SBATCH --partition=compute

module load openmpi
source /fsx/OpenFOAM/OpenFOAM-v2312/etc/bashrc

Is there just a broken link somewhere? I noticed the tutorial is for OpenFOAM-v2012, whereas I've installed the latest version OpenFOAM-v2312, so not sure if this is part of the issue. Any help is appreciated.

Thanks!

I have run the foamInstallationTest and got the output below. It looks like icoFoam was not installed correctly. I've tried doing a search on how to correct this but have not found any examples that are applicable to my application. If there are any thoughts on this it would be much appreciated.

Examine the contents of the FOAM_APPBIN and the FOAM_LIBBIN directories. They really should contain something...

[Gforce237]

Thanks for the response.

When searching for either directory (FOAM_APPBIN, FOAM_LIBBIN) in my OpenFoam-v2312 directory does not return anything. Is there a typical file path for these directories?

I am also not finding them in the .tgz files (which I downloaded from here: https://develop.openfoam.com/Develop...r/doc/Build.md)
