Running the nano-nozzel tutorial
 

hi every one
i wanted to test the MD solver in Openfoam by running the nano-nozzel tutorial.
here is the problem i encounter :

mehdi@mehdi-laptop:~/OpenFOAM/mehdi-1.6/run/tutorials/discreteMethods/molecularDynamics/mdFoam/nanoNozzle$ blockMesh

blockMesh runs with no problem
then

mehdi@mehdi-laptop:~/OpenFOAM/mehdi-1.6/run/tutorials/discreteMethods/molecularDynamics/mdFoam/nanoNozzle$ decomposePar

but when i try to run the case by
mpirun -np 4 gnemdFoam -parallel > log &
i get

[1] 4952
mehdi@mehdi-laptop:~/OpenFOAM/mehdi-1.6/run/tutorials/discreteMethods/molecularDynamics/mdFoam/nanoNozzle$ --------------------------------------------------------------------------
mpirun was unable to launch the specified application as it could not find an executable:

Executable: gnemdFoam
Node: mehdi-laptop

while attempting to start process rank 0.
--------------------------------------------------------------------------


what shall i do? :confused:

and when i try to run mdFoam
mehdi@mehdi-laptop:~/OpenFOAM/mehdi-1.6/run/tutorials/discreteMethods/molecularDynamics/mdFoam/nanoNozzle$ mdFoam

i get

// * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * //
Create time

Create mesh for time = 0

Nothing ??? :(:(

you need to initialize beforehand with "mdInitialise" (cf. Allrun)
