Question regarding density and viscosity related to pressure
 

Hi, novice FLUENT user here. I am modelling multi-phase flow of carbon dioxide through a pore space initially filled with water. I have defined the operating pressure as 10 MPa. My question is will FLUENT automatically change the density and viscosity of the materials to account for the high pressure? Or do I need to manually edit these properties in the Materials section before calculating the solution? Thanks.
