 Examples for different kinds of both coupled and decoupled models are isothermal two-phase models, isothermal two-phase two-component models, non-isothermal two-phase models, non-isothermal two-phase two-component models, etc.
 
-The following two sections of the tutorial demonstrate how to solve problems first using a coupled model (section \ref{tutorial-coupled}) and second using a decoupled model (section \ref{tutorial-decoupled}). Being the easiest case, a isothermal two-phase system (two fluid phases, one solid phase) will be considered.
