Result Types

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

Filling Results

Option Description
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.

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.

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.

Air Traps Locate air trapped in the mold during filling due to different flow patterns. Consider adjusting the venting in the simulation.

Weld Lines Locate regions during filling where two flow fronts meet. Such regions may cause structural and cosmetic issues.

Mold Temperature Review temperature variances in the mold.

Fiber Orientation Tensor Review diagonal and cross products results for the tensors. The result predicts the fiber orientation tensor for short fiber reinforced polymers.
  • XX: red color contour displays the tensor in the X-direction.
  • YY: red color contour displays the tensor in the Y-direction.
  • ZZ: red color contour displays the tensor in the Z-direction.
  • XY: displays the tensor on the XY-plane.
  • YZ: displays the tensor on the XZ-plane.
  • ZX: displays the tensor on the ZX-plane.
The solver writes the fiber orientation tensor in a result and ASCII files that you can inport into Multiscale Designer for further strength and failure analysis.

Packing Results

Option Description
Temperature Review temperatures during the packing phase. The temperature will decrease due to the temperature loss across the mold walls.

Velocity Examine velocity during the packing phase. Velocities will decrease until the fluid stops flowing.

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.

Mold Temperature Review temperature variances in the mold.

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.

Mold Temperature Review temperature variances in the mold.

Warpage Results

Option Description
Displacement Due to non-uniform cooling, the molded part can warp, which can cause the part to fold, bend, twist or bow. 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.

  1. 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.
  2. 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.
  3. 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.

  4. 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.

Add Callouts to the Results

Call out and review values for a selected result type at points of interest on your model using the callout icons in the Analysis Explorer.

After running an analysis, click the Show Analysis Results icon. The Analysis Explorer appears to the right of the model.

  1. To create a callout at a point of interest, click in the Analysis Explorer, select a Result Type, and then click a point on your model. Box-select to see the maximum value in an area.
    Note: The callout value applies to the currently selected run.
  2. To automatically create callouts showing where the minimum and maximum values occur for a result type, select a Result Type, and then click .
  3. Optional: To display callouts in a table, click in the Analysis Explorer.
    • Selecting a row in the table also selects the callout in the modeling window.
    • To show or hide a single callout, in the Callouts table, Name column, click .
    • To show or hide all callouts, in the Analysis Explorer, click .
    • To sort the order of a column in the table, click the column header. Or you can click or to select Sort Ascending or Sort Descending.

    • To add or delete columns on the table, right-click a column header, and then select or deselect a property.
