Result Types

Results are available for filling, packing, cooling, and warpage analysis stages.

Filling Results


Option	Description
Velocity	Examine the velocity vectors evolution during the filling of the mold. Click the Show and Options buttons to change to velocity contour fill animation.
Velocity Average	View the average velocity of the material through the part during filling.
Temperature	Review the temperature evolution of the fluid entering the mold cavity. Check regions for excessive heating or cooling. Determine the appropriate fill speed for uniform temperature distribution.
Flow Front Temperature	Review the temperature at the time of filling.
Temperature (Core)	Review the temperature in the central region of the part during filling.
Pressure	Review pressures inside the mold cavity produced during the filling stage.
Filling Time	Review the time it takes the material to reach different areas within the part. The filling results can help you determine the best way to fill the part and detect patterns that indicate the potential for incomplete filling, unbalanced flow, weld lines and air pockets.
Density	Review the polymer's density over time. Uniform density is ideal for high quality results.
Frozen Layer (%)	View the solidified and non-solidified regions of the part during filling.
Air Traps	Locate air trapped in the mold during filling due to different flow patterns. Consider adjusting the venting in the simulation.
Weld Surface Angle	A weld surface is generated when two polymer flow fronts meet. This can have an impact on both the appearance and strength of the part. The weld surface angle is the angle at which the two fronts meet, defined as 0º for a weld in which the fronts meet from exactly opposite directions, and increasing as the encounter is less direct. Weld surfaces above 135º (less than 45º from parallel) are not shown.
Thickness	Review the thickness of different areas of the part. Local part thickness affects local strain rates and heat flow. Abrupt changes in thickness cause uneven cooling, which can lead to part shrinkage and defects such as sink marks in the final part. This result can give insight into the entire process.
Mold Temperature	Review temperature variances in the mold.
Main Fiber Orientation	This is the main fiber orientation component Displays the orientation and modulus of the first principal component of the fiber orientation tensor. A value close to 1 implies that most of the fibers are oriented in this direction. A value close to 1/3 implies no dominant orientation (random).
Full Fiber Orientation	This result shows all the components of the Fiber Orientation Tensor.

Packing Results


Option	Description
Temperature	Review temperatures during the packing phase. The temperature will decrease due to the temperature loss across the mold walls.
Temperature (Core)	Review the temperature in the central region of the part during packing.
Velocity	Examine velocity during the packing phase. Velocities will decrease until the fluid stops flowing.
Velocity Average	View the average velocity of the material through the part during packing.
Pressure	Consider pressures during the packing phase. These results are useful to know points where the pressure is less than 0 to detect areas prone to suffer a sink mark defect.
Sink Marks	Detect surface depressions, usually in the thicker sections of the model, caused by shrinkage during the packing stage.
Density	Review changes in the polymer's density over time. Uniform density is ideal for high quality results. This result can help pinpoint the causes of such defects as sink marks and shrinkage.
Frozen Layer (%)	View the solidified and non-solidified regions of the part during packing.
Thickness	Review the thickness of different areas of the part. Local part thickness affects local strain rates and heat flow. Abrupt changes in thickness cause uneven cooling, which can lead to part shrinkage and defects such as sink marks in the final part. This result can give insight into the entire process.
Mold Temperature	Review temperature variances in the mold.
Volumetric Shrinkage	This result shows the local shrinkage (you can see the differences across the thickness) in the finished part.
Average Volumetric Shrinkage	This result shows the average shrinkage across thickness in the finished part.
Main Fiber Orientation	This is the main fiber orientation component Displays the orientation and modulus of the first principal component of the fiber orientation tensor. A value close to 1 implies that most of the fibers are oriented in this direction. A value close to 1/3 implies no dominant orientation (random).
Full Fiber Orientation	This result shows all the components of the Fiber Orientation Tensor.

Cooling Results


Option	Description
Temperature	Examine the temperature evolution once the mold is totally filled. You can determine the final temperature at which to stop the cooling phase.
Temperature (Core)	Review the temperature in the central region of the part during cooling.
Thickness	Review the thickness of different areas of the part. Local part thickness affects local strain rates and heat flow. Abrupt changes in thickness cause uneven cooling, which can lead to part shrinkage and defects such as sink marks in the final part. This result can give insight into the entire process.
Density	Review changes in the polymer's density over time. Uniform density is ideal for high quality results. This result can help pinpoint the causes of such defects as sink marks and shrinkage.
Frozen Layer (%)	View the solidified and non-solidified regions of the part during cooling.
Mold Temperature	Review temperature variances in the mold.

Warpage Results


Option	Description
Displacement	Detect folding, bending, twisting or bowing in the molded part, which is usually due to non-uniform cooling. The displacement contour displays how the part is warping so that you can make the appropriate corrective measures to the cooling rate, cooling channel design, or process data.

View Molding Defects

Fix issues with air traps, weld surfaces, and sink marks.

When the run is complete, click the Show Analysis Results icon or double-click the run the in Run Status window to view the results.
In the Analysis Explorer select the Filling stage, then view the results for Air Traps. This defect occurs when there is not enough venting, and air gets trapped in the mold.
Note: To fix issues with air traps:
- Optimize your design to create appropriate gating.
- Select low viscous materials, which will allow more air to be released.
- Add proper ventilation.
- Align your mold properly to help provide ventilation for trapped air.
Next, view Weld Surfaces for the Filling stage. This simulation shows the regions where two flow fronts meet. This defect can occur in parts with a core or insert. If the two fronts that meet have different temperatures, they may not meld completely in the mold because of a temperature gradient.
Note: To fix issues with weld surfaces:
- Select a material with a low melting temperature.
- Increase the injection temperature and speed.
- Modify the design to obtain a single flow.
- Increase the melting temperature of the material.
View Sink Mark results for the Packing stage. These defects occur in the thicker sections of the model when the cooling rate and compensation are not sufficient. Rib sections and internal fillets are the most common areas to be affected.
Note: To fix issues with sink marks:
- Redesign the thickest section where sink mark is occurring and try to reduce the thickness.
- During Packing, lower the mold temperature using the Cooling System.
- Increase the gate size to allow enough material to fill and pack the mold.
- Increase the holding temperature during the Packing cycle.

Callouts

Create, show, hide, and list callouts for selected result types at points of interest on your model.

After running an analysis, click the Show Analysis Results on the Analyze icon. Options for callouts appear in the Callouts section of the Analysis Explorer.


Callout Icon	Description	Note
Create, Show, and Hide Callouts	Click the icon, then click a point on the model to create a callout.	After creating callouts, click the icon to show/hide the callouts in the modeling window.
List Callouts	Display a list of all callouts in a table. Each callout is specific to the selected run.	Click the icons in the table to show/hide individual callouts.
Min/Max Callouts	Create a callout showing where the minimum/maximum value occurs for the selected result type.	Click the min/max callout in the modeling window to create a regular callout at the same location.
Options	Dynamic Callouts: Make callouts dynamic, so they display the value of the currently selected result type.	If you enable the Compare Results feature in a callout, the callout becomes static.
