Activity 5: Compare the results for the various studies

In this activity, you

• Compare the original and modified injection location results
• Compare the original and modified Simulation model results
• Decide which modfications should be made for this model.

Prerequisites

Activity 4 is completed.

Steps

1. Compare the two studies in Simulation model 1, and determine whether or not moving the injection location improved the result.

   1. On the Setup tab, click (Results panel > Simulation Results), to switch to the Results tab.

   2. On the Results tab, click (Display panel > Results), to show the standard results browser.

   3. On the Results tab, click (Compare panel > Compare) to open the Compare tab.

      Note: By default, two windows open, but you can select up to 4 separate windows.

   4. In the window on the left, select the original model 1 study 1. In the window on the right, select model 1, study 2 - move inj loc, and compare the Fill confidence results.

      Notice that by moving the injection location, the rib is slightly more likely to fill, but the far end of the part has become more difficult to fill.

   5. Switch to the Injection pressure result and notice that the maximum pressure has dropped with the new injection location.

   6. Switch to the Warpage tolerance result and notice that alongside the decrease in injection pressure, there maximum warpage has decreased slightly.

   7. Switch to the Sink mark depth result and notice that the maximum depth of the sink marks has also decreased.

2. Add the result from Simulation model 2 to the comparison, and decide whether making the wall thicknesses more uniform improved the likelihood of the part filling.

   1. On the Compare tab, click (Layouts panel > One Horizontal and Two Vertical Views) to add a third window.

      

   2. In the top window switch to model 1, study 1. In the bottom right window switch to model 2, move inj loc.

      Note: Remove the visible edges of the model to view the results more clearly.

      

   3. Cycle through the Fill confidence, Injection pressure, Warpage tolerance, and Quality prediction results and notice that the quality prediction is further improved by modifying the wall thickness.

   Based on a comparison of the results, moving the injection location and making the wall thicknesses more uniform have both improved the results, making it more likely that the part will fill and produce a quality part.

   You can continue to make modifications to the study setup. Remember that as you make changes to improve one aspect, such as balanced fill pattern, it is possible that those changes might adversely affect other aspects, such as warpage, and you'll need to make trade-offs between improvements in one area and its effect in another area.
