In this contribution we present investigations on modeling of freezing processes between two ice floes. In detail we show results on the ice formation (mass exchange between the constituents) and the temperature distribution under calm sea conditions. For the detection of energetic effects regarding the characterization and the control of the phase transition, a thermodynamical consistent approach is presented, see [1]. In the later contribution the resulting finite element is a four field formulation in terms of ice displacements, liquid pressure, temperature and volume fraction of ice and is used in the present paper. An advanced numerical example show that the simplified model is capable of simulating the temperature development and phase change.
