In the typical simulation, a flow front is provided, which can show the progression of flow. Some other
tendencies, such as hesitation, flow overlap, weld line strength, can be visualized better with the particle
tracer analysis. There are two typical tracer analyses:
Particle Tracer:
- Launches particles from the Melt Entrance and the particles progress through the entire part
individually.
- This type of analysis can allow for visualization of flow tendencies, such as hesitation, leading and
melt overlapping.
Weld Line Particle Tracer:
- Places particles on Weld Lines whenever they are formed. The particles then progress from there
to indicate their final location.
- This analysis indicates the strength of a weld line:
o If the particles do NOT progress from their initial position, then the weld line is static,
meaning it is weaker.
o If the particles DO progress from their initial position, then the Weld Line is blurred,
typically indicating a stronger weld line.
- This type of analysis can also be useful when evaluating the effectiveness of an overflow region.

The particle tracer analysis is a heavy calculation, meaning that the computation time will be marginally
longer than simulation without the particle tracer enabled.

2.4.5.2 Solver Acceleration
Solver Acceleration is the most optimal way to increase the efficiency of the computation. This value is a
general indication of the number of iterations made by the simulation during the Flow/Pack analysis
