The overlay function allows you to view more than one result at a time on the same model. 
 Fill analysis results show how a part fills, and identifies any potential flow problems. You can overlay combinations of complementary fill analyses to gain a greater understanding of polymer flow characteristics. Typical combinations of analyses results can include the following: 
- Fill time and Air traps 
- Fill time and Weld lines 
- Fill time and Fibre orientation 
 
Tip: To help visualize overlaid results, you can combine different plot display options. For example, you could display a pressure plot as a shaded result overlaid with a contoured Fill time result. 
To overlay a result, follow the steps below.
