Pls help me out here..this is my first run of openFOAM and im unable to find the error..im just trying to make air flow thru a square pipe:
FoamFile
{
version 2.0;
format ascii;
class dictionary;
object blockMeshDict;
}


converToMeters 0.01

vertices
{
(0 0 0)
(0 5 0)
(5 5 0)
(5 0 0)
(0 0 100)
(0 5 100)
(5 5 100)
(5 0 100)
};

blocks
(
hex(0 1 2 3 4 5 6 7) (20 20 1) simpleGrading(1 1 1)
);

edges
( /*define if not straight*/

);

boundary
(
inlet
{
type patch;


faces
(
(2 1 0 3)
);
}
outlet
{
type patch;
faces
(
(6 7 4 5)
);
}

upperWall
{
type wall;
faces
(
(5 6 2 1)
);
}
lowerWall

);
}
frontAndBack

);
}
);
mergePatchPairs
(
);

output from terminal

Any help would be very useful

Hi,

it must be:
convertToMeters 0.01;

You are missing the semicolon and there is a typo at "convert".

thanks Martin

Well spotted MartinB.

Also change the accolades after 'vertices' in culry braces, like so:

convertToMeters 1;
vertices
(
(0 0 0)
(4 0 0)
(0 1 0)
(4 1 0)
(0 2 0)
(4 2 0)
(0 0 2)
(4 0 2)
(0 1 2)
(4 1 2)
(0 2 2)
(4 2 2)
);
