I have to calculate the variation of liquid and gas over time and the pressure variation inside a tank (with a certain initial liquid nitrogen content) in which I supply heat from the outside. I have already configured the "two-phase fluid properties" block, but I don't know now how to proceed. I guess for this kind of problem i need to use the "receiver accumulator" block. Could anyone help me?? Thank you!!

The two absoluate reference block I believe will enforce the temperature and pressure to be 0K and 0Pa, respectively. Use Cap instead. Then set the initial condition for the accumulator to your desired conditions.

If you don't need to separate the vapor and the liquid part of the mixture, using a regular constant volume chamber may be sufficient as well.
