hello,

i am extremely new to OpenFOAM, im trying to make my first geometry and mesh using blockMesh. i just edited the blockMeshdict file from the cavity case for my geometry.
im trying to create a geometry for a simple 2D flat plate in laminar flow case
plate is 1m and the height of domain is 0.5m
-plate at the bottom, inlet on left , outlet to the right and farfield on top
if the errors seems very basic, plz forgive , this is only my 3 day on openFOAM

this is how i edited the blockmeshdict file -

convertToMeters 1;

vertices
(
(0 0 0)
(1 0 0)
(1 0.5 0)
(0 0.5 0)
(0 0 0.1)
(1 0 0.1)
(1 0.5 0.1)
(0 0.5 0.1)
);

blocks
(
hex (0 1 2 3 4 5 6 7) (50 60 1) simpleGrading (1 70 1)
);

edges
(
);

boundary
(
inlet
{
type patch;
faces
(
(0 4 7 3)
);
}

outlet
{
type patch;
faces
(
(1 2 6 5)
);
}

farfield
{
type symmetryPlane;
faces
(
(3 7 6 2)
);

plate
{
type wall;
faces
(
(1 5 4 0)
);
}

frontAndBack
{
type empty;
faces
(
(0 3 2 1)
(4 5 6 7)
);
}
);

mergePatchPairs
(
);

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

and this is the error i get...

--> FOAM FATAL IO ERROR:
"ill defined primitiveEntry starting at keyword 'boundary' on line 41 and ending at line 94"

file: /media/sf_OpenFOAM/flatplate/constant/polyMesh/blockMeshDict at line 94.

From function primitiveEntry::readEntry(const dictionary&, Istream&)
in file lnInclude/IOerror.C at line 132.

FOAM exiting

all help is greatly appreciated, thanks in advance,

Good morning Joseph,

You are missing a curly bracket, }, at the end of your farfield definition.

Kind regards,

Niels

Thank you., i knew it must be something stupidly simple like that.

it worked out well. so went ahead and setup the rest of the case. (by my understanding standards ) but now have run into a diff prob.

im trying to run the flat plate case using icoFoam for 1000 iterations with a deltaT of 0.01, so total 10 secs.
so my simulation runs until 1.66 secs i.e. 166 iterations. then at 1.67 i get the following error and dump msg.. ive included the msg frm 1.66 secs for ref if needed..

I apologize if its again something stupid. like i mentioned in my previous post, im very new and trying to learn on my own... im not completely confident about my case setup also.

Thanks a lot and i appreciate your time...

Hi every one!
Would any one please help me with similar problem?
I have attached my blockMesh file and have an error like the following when running blockMesh:
--> FOAM FATAL IO ERROR:
"ill defined primitiveEntry starting at keyword 'blocks' on line 299 and ending at line 1753"

Thanks!
