The Gate location analysis result rates each place on the model for its suitability for an injection location.
This result is output using the Gate Region Locator algorithm, which uses a combination of conditions to determine the best injection location and subsequent injection locations. The most suitable areas are rated from most suitable (best) to least suitable (worst).
When one or more injection locations already exist, this result suggests the best place for the next injection location. It balances the flow, so that areas filled from each gate fill at the same time.
To use the Gate Region Locator algorithm, place an injection location somewhere within the recommended locations, in a position that best suits the mold or part design constraints and then run a Fill analysis. Test several locations by running a Fill analysis from each location and then compare the results.
The best areas shown on the result do not necessarily represent a good solution (high quality part, or high confidence of fill), but rather the best one for the case at hand using the selected material.
