eng.masoud New Member Masoud Mo Join Date: May 2018 Posts: 6 Rep Power: 8	Hi fellows, In my 2D simulation (VOF - 2 phase), I want to have a velocity-inlet boundary condition that moves along x-axis with speed of 0.07 m/s. During this moving the second phase liquid comes out with speed of 0.02 m/s from inlet. Would you please provide me some guidance on regarding the movement of velocity-inlet BC? Is there a specific UDF to handle it? Thanks
