Dear all,

I working on a customized version of movingConeTopoFvMesh (called it topoConeTopoFvMesh2) to move my grid (dynamicFvMesh).

I defined an access function
Code:
volScalarField alpha()
{
    return alpha_;
}
Now, I'd like to call this function in my main file.
Code:
   alpha= mesh.alpha();
gives me:
Code:
error: ‘class Foam::dynamicFvMesh’ has no member named ‘alpha’
   alpha= mesh.alpha();
How can I access function this alpha() from my main file?
Cheers,
Cyprien

Hi,

1. You can use refCast on mesh to convert dynamicFvMesh to topoConeTopoFvMesh2 (something like
Code:
const topoConeTopoFvMesh2& my_lovely_mesh = refCast<const topoConeTopoFvMesh2>(mesh)
). Then use alpha method of my_lovely_mesh.

2. You can use
Code:
mesh.lookupObject<volScalarField>("name of alpha_ field")
.

I got it! Thank you. I indeed have to declare my mesh as a topoConeTopoFvMesh2.
