Hi

I'm trying to mesh a sphere with hexahedron grids.
I used a Gmsh code found in this forum to do so. using gmshToFoam to convert the mesh gives me this error:

--> FOAM FATAL IO ERROR: 
wrong token type - expected word, found on line 0 the label 1

file: IStringStream.sourceFile at line 0.

From function operator>>(Istream&, word&)
in file primitives/strings/word/wordIO.C at line 74.

FOAM exiting

what is wrong here?
you can find the mesh file in attachment. (I had to remove some lines some where in the middle of .msh file to keep it under 195kB for the attachment limit)

Hi,

Since error is caused by your original file, there is no use in the file with "some lines some where in the middle" of the file. Please post your original file.

And since your untitled.msh is something LEGALLY generated by LEGALLY acquired Gmsh, you can try to use, for example, Dropbox to host your file.

UPD. Anyway, you are generating this msh file from geo file, post your geo file. It is weights much less than msh.

this is the original file.
https://www.dropbox.com/s/n2xn2pyspt...itled.msh?dl=0

And where is the header of the file? In general Gmsh file starts with:

$MeshFormat
2.2 0 8
$EndMeshFormat
$Nodes
<number of nodes in the file>
...

Since it is absent, you get your error.

Hi,
How can I solve the next problem with gmsh:
gmshToFoam command not found

[ncrasta]

Hi foamers,
I also get the following error with gmshToFom command. What could be the possible reasons?



Thanks,
Naveen
