1812 is running fine serial in WSL with Ubuntu bash

with parallel mpirun getting the following problem:

mpirun –np 2 buoyantBoussinesqSimpleFoam.exe –parallel

--------------------------------------------------------------------------
mpirun was unable to find the specified executable file, and therefore
did not launch the job.  This error was first reported for process
rank 0; it may have occurred for other processes as well.

NOTE: A common cause for this error is misspelling a mpirun command
      line parameter option (remember that mpirun interprets the first
      unrecognized command line token as the executable).

Node:       LEMM07
Executable: –np
--------------------------------------------------------------------------
2 total processes failed to start

I don't see the real cause of the problem.

Thx for any advice

Hi Heinrich,

May I know why are you using buoyantBoussinesqSimpleFoam.exe instead of only buoyantBoussinesqSimpleFoam in the following command

mpirun –np 2 buoyantBoussinesqSimpleFoam.exe –parallel
