Thank you for your reply. I defined the enthalpy curve in the engeeniering data and did exactly the same as the lady in lesson 4 did. But still I get the temprature curve as that the enthalpy has not been defined (the curve in the phase change period is not constant), which of course wrong. 

Could it be that I need to activate some solver or energy equation or is there a special command that I need to use. It would be so helpful if you explain more for me. 

I did the following steps exactly: 

1- define engineering data (all values I get from the lady in lesson 4: phase change material) 

2- Draw the geometry 

3- meshing and addition of boundray condition 

4- solve and draw the temprature regarding to time 

and as I sayed the temprature should be constand on 0°C but still I dont get this results and it seems the solver doesent recognize the definition of enthalpy in engineering data. Would you help me please and give some tips, steps or advices.
