I´m having several difficulties with the pressure calculation inside my domain filled with water.

I tried to use constant properties water and the pressure remained constant.

I tried to use water defined by the IAWPS database and the pressure reaches the maximum value of my table (200 bar) really fast, which doesn´t correspond to the real-based behaviour.

I tried to define liquid water with the correspondent NASA polymonials and the software solver crashes with the following message:

Error in subroutine CALVAR_PROP :
Error calculating Thermal Expansivity
GETVAR originally called by subroutine CAL_GVar


Can anybody help me with the material definition of water in order to get the true specific heat and density variation with temperature which will result in the true pressure?
