The aim is to make a simulation and animation of fluids in Gas Metal Arc Welding as the final target of the work.
Suitable fluid simulation algorithms to simulate a gas are either the Smoothed Particle Hydrodynamics algorithm (SPH)
[1] or Computational Fluid Dynamics (CFD). This work used CFD to simulate a high viscous fluid and fluid melting.
The focus was on both high and low fluid viscosities and used a conventional high viscous fluid method [2-4]. Unlike
former works, which used extensive simulation, here only the fluid of immediate concern was simulated. At the fluid
interface, if the fluid passes into a new space, the values for the empty space are extrapolated from the values at the
fluid interface
