as boundary conditions, such as energy and free interface, are derived in detail. The
model can simultaneously couple and simulate transient phenomena such as threedimensional heat transfer, flow, and evolution of free interface of the pore in deep
penetration laser welding.
The high-precision Level Set/Particle Level Set method is used to track the transient pore moving interface. Based on this, a fast and robust computation method
is proposed to solve the energy density distribution on the wall of the pores with
any complex shapes, and the high-precision implicit scheme is used to discretely
solve the corresponding energy equation and momentum equation. Furthermore, the
corresponding discontinuous boundary conditions, such as temperature, pressure and
viscous stress, are accurately processed.
