Hi OpenFOAMers,

My problem is similar to these two threads:

How to get cell indices and manipulate field data

runTime mapFields from fineMesh to coarseMesh

I want to do data exchange for internal field values between two identical meshes with different mesh density.

Each mesh has own solver. For example, solver1 gets results of velocity and sends them to solver2 for temperature calculation. And temperature is returned to solver1 for velocity calculation, the loop continues like this.

Those two threads make use of the code of mapfields and implement it in solver.

I'm not sure if I need to merge those two solvers as a new solver before using mapfields code in the solver.

Where to the put the code in the solver?

Similar work in OpenFOAM has been found in journal paper, it states that "The computations on the two meshes are fully
coupled, meaning that data (temperature from macro- to meso-,
and solid fraction from meso- to macroscale) is exchanged in both
directions at every time step via a linear interpolation framework"

I'm not sure how the author implement the data exchange, limited information provided in the paper.

Thanks in advance.
