     this paper introduces the chattering problem in dynamic mathematical two-phase flow models. the real system object of study is also introduced, the diss test facility, a parabolic-trough solar power plant using as heat transfer fluid the steam–water mixture. a dynamic model for studying its behaviour was previously developed using modelica as the modelling language, in this model the chattering problem arises and therefore not allowing to take full advantage of dynamic simulations. the chattering problem increases the computational time needed for simulation and sometimes dynamic simulations do not finish at all. a heuristic method, which minimises the effects of the chattering problem, is discussed and results which reduce the computational time for dynamic simulations are given.
