Default Reading a case with different mesh

Hello,
I am solving a flow (let's call it simulation0) that uses the solution of another simulation (let's call it simulation1) to compute some coefficients needed for the simulation.
I read the variables from simulation1 like:

Y_ref.set
(
I
new volScalarField
(
IOobject
(
name_Yref,
location_simulation1,
mesh,
IOobject::MUST_READ,
IOobject::NO_WRITE
),
mesh
)
);

But, "mesh" is the mesh of simulation0, so the dimensions don't match with simulation1.

I tried to read the mesh of simulation1 like following, but I need runTime or an object similar which I don't know how to reach:

Foam::fvMesh mesh1
(
Foam::IOobject
(
Foam::fvMesh::defaultRegion,
location_simulation1,
runTime,
Foam::IOobject::MUST_READ
)
);

How can I read it?

Eva.

Hi,

i guess this question is already up for a couple of days, but maybe this will help:
If you want to read in a mesh from a different directory than constant (I assume here is your mesh from simulation0) you have to replace Foam::fvMesh::defaultRegion with the directory.

e.g.
Foam::fvMesh mesh1
(
Foam::IOobject
(
"region1", // read the mesh from constant/region1 directory
runTime.time().timeName(), // adjust the timestep here in case you have different meshes for different times
runTime,
Foam::IOobject::MUST_READ
)
);

Best regards
Felix
