Hi

I've converted a 2d mesh from a commercial software to openfoam and now i want to convert it to a 3d mesh(2d with 1 layer in z direction).
I did the same correctly some months ago with openfoam 2.1 but now for 2.2 it does not work.
When i use the command " extrude2DMesh 0.01" i get the error :
----------------------------------------
--> FOAM FATAL ERROR:
0.01 not found in table. Valid entries:
2
(
MeshedSurface
polyMesh2D
)


From function HashTable<T, Key, Hash>:perator[](const Key&) const
-----------------------------------------
I used all formats e.g extrude2DMesh '0.01' and .... but none of the work.
I would appreciate any idea.

You need this dictionary in your system/ folder:

/*--------------------------------*- C++ -*----------------------------------*\
| =========                 |                                                 |

{
    version         2.0;
    format          ascii;
    class           dictionary;

}
// * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * //

extrudeModel        linearDirection;

patchType           empty;

nLayers             1;

expansionRatio      1.0;

linearDirectionCoeffs
{
    direction       (0 0 1);
    thickness       0.01;
}

and run either:

extrude2DMesh MeshedSurface

or

extrude2DMesh polyMesh2D

Depending on whether your initial mesh is a meshed surface or a 2D polyMesh

Thank you for your answer.
Would you please tell me how i should compile this code into my system folder?
Also , This is because of the new version of openFoam?because in the previous version i just used extrude2DMesh command.
Thank you in advance.

You don't compile anything, just put that in the system/ folder of your case directory.

Yes, extrude2DMesh changed to include more functionality.
