Run Analysis

Define parameters and execute an analysis to understand filling, packing, cooling or warpage events during molding. Generate results for individual or combined events.

Complete the model setup before running an analysis.
Note: Analysis results are saved in the folder specified in your Preferences settings under Molding > Analysis > Run Options.
  1. Click Run Analysis on the Analyze icon..

  2. Define the parameters for the analysis.
    Tab Option Description
    Stages

    Name Type the name of the run. By default, the name of the model is used.
    Speed/Accuracy Adjust the slider to determine whether the results returned are faster or more detailed.
    • Drag the slider to Fast to apply an element size that is equal to the average thickness * 2.
    • Drag the slider halfway between Fast and Detailed (Medium), to apply an element size that is equal to the average thickness * 1.2.
    • Drag the slider to Detailed to apply an element size that is based on the thickness and number of mesh layers. The default number of layers = 5. The minimum number of layers for filling, cooling, and warpage = 2; packing = 4; fibers = 5.
    Note: Some result types (e.g. Velocity Average) are calculated only when the slider is set to Fast, while others (e.g. Effective Strain Rate) are calculated only when the slider is set to Detailed.
    Auto Mesh Enable this option to allow Inspire Mold to automatically determine the optimal mesh size for the analysis.
    Note: If you enable Auto Mesh, Average thickness and Element Size will be disabled.
    Average thickness

    Enter the average thickness of the part. The software creates the mesh based on this value.

    Element size Enter the average element size for the part cavity. The software creates the mesh based on this value.
    Number of layers Enter the number of element layers to be generated. To reduce computation time, specify 3 to 5 layers. To improve accuracy, specify 6 or more layers.
    Note:
    • The Number of layers field is unavailable in a Fast analysis.
    • If the value in thi field is less than 5, the Compute Fiber Orientation feature, below, will be unavailable.
    Filling
    Select to examine the flow pattern, temperature, and pressures associated with the material entering into the mold. Select the Compute Fiber Orientation option to include fiber orientation in the analysis.
    Note: You must also define or select a material with fiber properties when assigning a material to your part during the analysis setup.
    Packing Select to calculate the pressure necessary during solidification to compensate for contraction due to temperature.
    Cooling Select to view cooling results in which solidification starts with a totally full mold and ends at a specified temperature or time.
    Warpage Select to examine evidence of warpage. Warpage can occur when a material shrinks non-uniformly due to high cooling rates, mold restraint, or temperature differences that create internal stresses.
    Note: If the Speed/Accuracy slider is set to Fast, you must also select the Filling, Packing, and Cooling options to generate warpage results. If the slider is set to Accurate, only the Cooling option is required.
    Select Part Click this button, then select a part in a multi-cavity mold for warpage analysis.
    Note:
    • This control is only available when your model has at least two different parts in a multi-cavity mold.
    • Warpage results will be calculated for the selected part only.
    • Other results will be calculated for all parts.
    Configuration

    Filling, Packing, Cooling HTC Enter the Heat Transfer Coefficient. W/m2K for each stage of the process.
    Room temperature Enter the ambient temperature of the work environment
    Virtual mold temperature Set the desired starting temperature for the mold.
    Improved accuracy fiber calculation Enable this option to get a longer run time and a more precise fiber calculation.
    Use interaction Coefficients Enable this option to access the coefficient and thickness fields below.
    Core Interaction Coefficient Specify the core interaction coefficient.
    Wall Interaction Coefficient Specify the wall interaction coefficient.
    Wall Thickness Specify the wall thickness.
  3. Click Run.
    The run status is displayed.
