Default buoyantFoam problem with meshToMesh

Hi everyone, I'm trying to make a simulation of a moving inflow, it should simulate the wearing out of an electrode. The Openfoam version is OF.org V10.

In this process I used dynamicMeshDict to make the mesh move, when the deformation of the mesh was no longer acceptable I wanted to do a meshToMesh.
In this step I have an error:
Code:
 FOAM FATAL ERROR:
 V0 is not available

 From function const Internal& Foam::fvMesh::V0() const
 in file fvMesh/fvMeshGeometry.C at line 296.
I'm trying to understand what's wrong but comparing it with movingCone I don't think there's any error in the setting.



Searching online I found that this problem was present in XiFoam as "XiFoam: Removed redundant rhoEqn solution after mesh topology change". The git hash is

7dd5c4d3fac0704492a5b81f3315abe7d3443a6f .


I tried to look for some redundancy in this case too but I couldn't find anything. Does anyone know this error or how to fix it

?

At the moment I think the error occurs in this area of ​​the code:

Code:
         autoPtr<volVectorField> rhoU;

         if (rhoUf.valid())
         {
             rhoU = new volVectorField("rhoU", rho*U);
         }

       // Update the mesh for topology change, mesh to mesh mapping

         mesh.update()
I think something is interfering with mesh.update(). I tried to understand in update() of the MeshToMesh file what could go wrong but I still haven't been able to figure out what's wrong.if I comment mesh.update() the count continues correctly.


All fields are printed correctly (even V0). It makes me think something is going on with directories.

it seems that the error is generated from this point, we are in fvMeshGeometry.C.


Code:
 const Foam::volScalarField::Internal& Foam::fvMesh::V0() const
293 {
294
295     if (!V0Ptr_)
296     {
297         FatalErrorInFunction
298             << "V0 is not available"
299             << abort(FatalError);
300     }
301
302
303     return *V0Ptr_;
304 }
What I understand is that the *V0Ptr_ pointer is missing, inside the fvMesh.C inside the file I find a lot of information that has to do with V0Ptr_ does anyone know where the error could be?
