Default Phase Change not Visible when Switching from Velocity Inlet to Pressure Inlet

Hello everyone,

I am currently facing a challenge in simulating flow boiling using the Volume of Fluid (VOF) method in fluent. When I use the velocity inlet boundary condition, the simulation runs smoothly and successfully captures the phase change.

However, when I switch the boundary condition to pressure inlet, the phase change is not visible even though the pressure and temperature meet the conditions for phase change. I have ensured that simulation parameters and settings are correct.

I would like to ask for advice or guidance from all of you. Has anyone experienced a similar situation? Are there specific settings to be mindful of when using a pressure inlet for flow boiling simulation with VOF?

I truly appreciate any help or insights you can provide. Thank you very much!

You need to specify the volume fraction at the inlet. Simply specifying temperature and pressure does not say anything about the phase of the material.
