I recommend reading the user guide. None of your OpenFOAM executables are present. Either you didn't compile properly or you didn't source.

Hi,

you need to decompose your grid before using the parallel mode. Because it requires the decomposed processor directories to start the simulation and i cannot see the processor rank directories in the attached file in your working directory. Make sure that you have the "decomposePar" dictionary in your "system" folder. If not then do that, otherwise you can start the computation in serial mode taking into account the size of your mesh.

good luck
