Hello,

1. I am trying to convert a gmsh using gmshtoFoam. The .msh-file I use is good, because I see a nice mesh in the gmsh GUI. When I type
gmshToFoam blok01.msh

the console answers (only the lower lines)

Code:
...
Unhandled element 1 at line 430
Unhandled element 1 at line 431
Unhandled element 1 at line 432
Unhandled element 1 at line 433
Unhandled element 1 at line 434
Unhandled element 1 at line 435
Unhandled element 1 at line 436
Unhandled element 1 at line 437
Unhandled element 1 at line 438
Mapping region 0 to Foam patch 0
Cells:
    total:0
    hex  :0
    prism:0
    pyr  :0
    tet  :0



No cells read from file "blok01.msh"
Does your file specify any 3D elements (hex=5, prism=6, pyramid=7, tet=4)?
Perhaps you have not exported the 3D elements?

    From function readCells(..)
    in file gmshToFoam.C at line 662.

FOAM exiting

My blok.msh file is attached.



2. How do I define the patches? I assume I have to make physical surfaces in the .geo file, but this has not been succesfull so far.

Hello,

Best regards,

I fell upon this thread when looking up the error.

I got the same error because I had forgotten to define physical surfaces in the .geo file.

I did not look at your .geo file (can't find it/not attached anymore, new guy on the forum here), but I assume that all surfaces must have a physical name.

This is for someone in the future like me who might get the same error.
