Using solution from another simulation as inlet profile


I have some sort of 3D fluid flow simulation (simulation No.1) where I save the fluid velocity at outlet as h5 file and I would like to use that data for inlet profile for another 3D fluid flow simulation (simulation No.2). However, I am stuck how to incorporate velocity as inlet profile.

These two different simulations have different geometry expect that outlet mesh of simulation No.1 is the same as inlet mesh of simulation No.2

I know that there are SubMesh and MeshView function that can be useful for what I want to do, but I need to avoid using these two functions for some reason. (I will run simulation in parallel and that causes this problem)

I would be very happy to know if someone can point out useful functions or some example codes for this specific purpose.
