Hi,

I have a VOF simulation which the gas is compressible and the liquid is assumed as incompressible.

I set the boundary condition for both as mass flow inlet and I have a weird problem. when I want to initialize the problem from liquid or gas inlet it says the velocities are zero. but when I make the gas incomp. or turn off the VOF, it is resolved.

Could anyone help me on that?

Regards;
