Hello to everyone, I'm using OpenFoam 2.3.0. I'm facing a problem with the function mirrorMesh that should be simply to solve..
I have make a simple mesh of an half cylinder in Gambit and saved in msh format.
I would like to reconstruct the entire mesh in OpenFoam by mirroring it.
I initialy convert the mesh in the openfoam format using
fluent3DMeshToFoam half_cil.msh
And this creates the polymesh folder.
Then when I try tu run the command
mirrorMesh
But I get the followng error:

--> FOAM FATAL ERROR:

request for objectRegistry region0 from objectRegistry half_cil failed
available objects of type objectRegistry are
0()

From function objectRegistry::lookupObject<Type>(const word&) const
in file db/objectRegistry/objectRegistryTemplates.C at line 198.

FOAM aborting

What could be the cause of this error?
I have set the mirrorMeshDict file as follow:

/*--------------------------------*- C++ -*----------------------------------*\

}
