the vaporised zone should be defined as pressure ?

hi,all The very strong density of power delivered by the laser beam causes the metal to boil a few milliseconds after the beginning of irradiation. The pressure created by the intense vaporisation tends to dig the molten metal zone.That is,recoil pressure make the free surface of the molten metal zone depressed.i want to model the depressed surface and track free surface using VOF method.My question is that the vaporised zone should be defined as pressure inlet or mass inlet or velocity inlet?

Hello! Did you add the recoil pressure successfully? Thank you!

Hi there.. can you tell me how you added recoil pressure to the momentum equation
