3 Coupling Model and Numerical Computation Method of Keyhole and Weld Pool
Fig. 3.7 After 9950 steps
are calculated (Particle Level
Set)
Fig. 3.8 Particle shapes
corresponding to Fig. 3.7
interface is tracked by the Level Set. Figure 3.7 shows that the Particle Level Set
method can be used to better simulate the severe tear deformation of the moving
interface.
In order to further test the developed interface tracking technology, the numerical
test is carried out using the classic calculation example of Zalesak sphere rigid motion.
The so-called Zalesak disc is actually a three-dimensional sphere with a square notch.
Assuming that the sphere is in a computational space [0, 100] × [0, 100] × [0, 100]
