My Problem
When I use the command simpleFoam, I get the following error
================================================== ==============
No MRF models present

No finite volume options present

Starting time loop

streamLine streamlines:

keyword direction is undefined in dictionary "/home/sid/CFD/lily/postrun/system/streamlines"

file: /home/sid/CFD/lily/postrun/system/streamlines from line 13 to line 20.

    From function const Foam::entry& Foam::dictionary::lookupEntry(const Foam::word&, bool, bool) const
    in file db/dictionary/dictionary.C at line 566.
================================================== =============
What I tried
I tried to create
direction (0 0 1);
in streamlines.c to only find later it wasn't helping.

for reference,
I'm simulating a cylinder.stl file as shown in

And I get the error at 12:16

streamlines.cfg is located in:


edit streamlines.cfg to look like this:

/*--------------------------------*- C++ -*----------------------------------*\
========= |
\\ / F ield | OpenFOAM: The Open Source CFD Toolbox
\\ / O peration | Website:
\\ / A nd | Version: 6
\\/ M anipulation |

type streamLine;
libs ("");

executeControl writeTime;
writeControl writeTime;

setFormat vtk;
direction forward;

lifeTime 10000;
nSubCycle 5;

cloudName particleTracks;

type lineUniform;
axis x;
start $start;
end $end;
nPoints $nLines;

// ************************************************** *********************** //

Why does this work? Not sure. I happened to have openfoam installed on multiple computers and this tutorial worked on one but not the other. When I traced the errors back, I noted streamlines.cfg was missing lines for the computer that didn't work. Perhaps these were put in place when I ran other simulation tutorials in the user manual.
