I’m using preCICE to couple two codes: the lattice Boltzmann code LUMIS and OpenFOAM. LUMIS has a time step 10 times smaller than OpenFOAM so during the coupling LUMIS subcycles before exchanging data with OpenFOAM.
The preCICE website shows that preCICE allows time interpolation. What is exactly the time interpolation? Is it activated automatically when subcycling?
