Problem running potentialFoam

ivanfb95 · March 3, 2017, 07:22

I have a problem trying to running potencialFoam in OpenFoam 4.1
First I had run decomposePar (8 subdomains)
Then I want to run: potentialFoam 8 -noFunctionObjects
The following error is displayed:

Usage: potentialFoam [OPTIONS]
options:
-case <dir> specify alternate case directory, default is the cwd
-initialiseUBCs Initialise U boundary conditions
-noFunctionObjects
do not execute functionObjects
-pName <pName> Name of the pressure field
-parallel run in parallel
-roots <(dir1 .. dirN)>
slave root directories for distributed running
-withFunctionObjects
execute functionObjects
-writePhi Write the velocity potential field
-writep Calculate and write the pressure field
-srcDoc display source code in browser
-doc display application documentation in browser
-help print the usage

Using: OpenFOAM-4.1 (see www.OpenFOAM.org)
Build: 4.1

--> FOAM FATAL ERROR:
Wrong number of arguments, expected 0 found 1

FOAM exiting

Can anybody help me?

Thanks.

Hi,

The syntax to run in parallel is:

Code:

mpirun -np <number of processors> <solver/utility name> <options for solver/utility>

In your case, you should have put it as:

Code:

mpirun -np 8 potentialFoam -noFunctionObjects
