Dear Foamers,

I am new to OpenFOAM. This is my first simulation using OpenFOAM. When I did blockMesh, I got the following error message:

--> FOAM FATAL IO ERROR:
"ill defined primitiveEntry starting at keyword 'blocks' on line 75 and ending at line 179"

Would anyone have ideas how to solve it?

Many Thanks!!

My blockMeshDict is as follow:

FoamFile
{
version 2.0;
format ascii;
class dictionary;
object blockMeshDict;
}
// * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * //

Hi,

Code:
hex ( 0 1 5 4 16 17 21 20 ) (20 20 5) simpleGrading ( 0.75 0.75 1 )
hex ( 1 2 6 5 17 18 22 21 ) (60 40 5) simpleGrading ( 1 0.5 1 )
Because in block 0 the edge connecting vertices 1 and 5 has 20 divisions, while in block 1, the same edge has been stated to have 40 divisions.

Cheers,
Antimony
