Hello,

I am a new OpenFoam user, and I have many difficulties to understand this software. I have to model a rocket tank, first I have to make the mesh:

/*--------------------------------*- C++ -*----------------------------------*\

FoamFile

format ascii;
class dictionary;
location "constant";
object blockMeshDict;
}

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

I created two blocks, to model the liquid volume. But when I try to use blockMesh this error message appears:
FOAM aborting

If someones could help me, i will be grateful.

Thanks
