Hi everyone. I got a problem when creating mesh. No matter what king of mesh I use, gmshToFoam, fluentMeshToFoam, or blockMesh, it always reports

FOAM FATAL IO ERROR:
Illegal dictionary Entry or environment variable name "start"
Valid entries are
2
(
type
axis
)

How could I solve this problem?
Appreciate in advance.

Hi,

Based on what you have posted, it would seem that you have used the wrong/invalid keyword.

Where are you getting this error? Can you post the entire error message? OF usually tells you in which file and in which line of that file the error has occurred and will help in troubleshooting.

Hope this helps.

Cheers,
Antimony

Hi Antimony. Thank you for replying. Here's the total message I got. Same thing happens on gmsh and blockmesh.

Hi,

OK this is good. Gives us more information.

Look at this line of the error message:

Code:
file: /home/jamie/OpenFOAM-6/laminar/pitzDaily/system/streamlines.uniformCoeffs from line 25 to line 26.
So there is some issue with the streamlines definition in what seems to be a "streamlines" file.

Since you are only trying to convert the mesh the simplest solution for you is to rename the streamlines file and comment it out wherever it is being invoked (somewhere in controlDict I should imagine)

Hopefully this helps you to get the mesh!

Cheers,
Antimony

Hi Antimony. I got the mesh succesfully, simply by deleting "streamline" and "blockMeshDirect" file. Thanks again for your help!

Best
