Default using mpirun

I am new to mpirun in linux
I'd like to use mpirun to apply simpleFoam using a network with 2 nodes.
to do that, I copy airfoil2D in tutorial folders and share it to client nodes using "nfs".
I am able to use mpirun in loacl machine by applying this command;
$mpirun -np 4 simpleFoam -parallel
but the problem is when I want to employ another node, let's say client, to use mpirun. the command I have used is as below:
$ mpirun -np 4 --hostfile hostFile simpleFoam -parallel
but it doesn't work. while my own code ( printf('hello') ) works well as below through network:
$ mpirun -np 4 --hostfile hostFile test -parallel

can anyone help me what's the problem?

You need to provide more details on the error. Try:

mpirun –hostfile <machines> -np <nProcs>
<foamExec> <otherArgs> -parallel > log &
