fluid79

can fluid80 be used to simulate fluid trapped inside a cavity with Pressure(DOF)
i want to couple a volume of fluid with a rubber container where the container will be deformed causing pressure rise inside the fluid
however, when i experiment with fluid80, there seems to be no DOF for pressure, and there's no pressure results even when pressure is applied to the fluid. Also the volume decreases which is not what i want
in this case, which element should i use for the constant volume fluid

thanks

Please try with the example in Chapter 7 Ansys guide, part VOF Analysis. I think it is little similar with your problem.
Hope it help
