Hello everybody,

I am currently working on simulations of conjugate heat transfer problems. The partitioned approach was used, i.e., solving heat conduction in the solid domain and convection in the fluid domain separately with a coupling provided by a pair of BCs at the solid-fluid interface.
I have implemented a Dirichlet BC for the solid domain and a Neumann BC for the fluid flow. What I want to do now is to update the solid BC after a couple of fluid flow calculations. I have no idea about how to handle the two different time steps (solid time step and fluid flow time step). What should I do?
