Hello,

I have a problem with an already exisiting case which is discribed here:
http://openfoamwiki.net/index.php/Co...oughnessToFoam

The code is hosted on Github:
https://github.com/hananel/roughnessToFoam

I tried to launch the case, but it doesn't work. I found in other threads that this data was created in OpenFoam 4 and I have the version 5.0.1 .

Do you maybe know what I need to modify so that it works.

Il also tried the commands:
blockMesh
snappyHexMesh -overwrite
But then the following error message occurs:

--> FOAM FATAL ERROR:
Number of cells in mesh:8000 does not equal size of cellLevel:24880
This might be because of a restart with inconsistent cellLevel.

From function Foam::scalar Foam::hexRef8::getLevel0EdgeLength() const
in file polyTopoChange/polyTopoChange/hexRef8/hexRef8.C at line 355.

.
.
.

Thank you for your help!

Hi,

Based on your error message, it would seem like that you would need to clean your case before beginning the meshing process again. Have you given that a try?

Delete the points/faces/cellZones/boundary files in polyMesh folder and try running from blockMesh again.

At the very least the error message that you are seeing right now, should go off.

Cheers,
Antimony

Thank you for the answer, but I already tried it.

I changed the commands to:
blockMesh
decomposePar
snappyHexMesh

Now, the mesh is created. But how does it work to take the roughnesstoFoam into account?
