Microchip Encapsulation analysis results

    This help topic provides an overview of the results generated by a Microchip Encapsulation analysis.

    Text based results

    The following table lists the text results generated for a Microchip Encapsulation analysis.

    Graphical results

    The following table lists the graphical results that are created by a Microchip Encapsulation analysis and indicates whether each result is supported for the following analysis technologies:

    • Midplane
    • Dual Domain
    • 3D

    A Microchip Encapsulation analysis generates the filling, curing, and stress results listed in the table below. For more information about a result, including how to interpret the display, click on the result name.

    NoteThe Microchip Encapsulation results generated will depend on the mesh type, and the wire sweep/paddle shift related solver parameters that you set. Using the advanced solver settings in the Process Settings Wizard, you can select a small deflection or large deflection Stress analysis, and you can select whether the wire sweep/paddle shift simulation should be performed by Autodesk Simulation Moldflow Insight Stress or Abaqus.
    TipTo display results of a 3D Wire Sweep analysis effectively, it is important to enable the results visualization option to Display 1D elements as segments. If this option is not enabled, result display could be very slow, especially on models that contain many wires.

    Click Application menu, then click Options File:Simulation_Moldflow/enu/2013/Help/Communicator/0566-Results566/0816-Microchi816/ac.menuaro.gif Results tab and in the Optimize memory for results display area, click in the Display 1D elements as segments checkbox to enable this option.

    1For Midplane and Dual Domain analysis technologies, these results are produced only when you have selected an analysis sequence that includes the Incompressible solver.
    2For Midplane and Dual Domain analysis technologies, these results are produced only when you have selected an analysis sequence that includes the Compressible solver.
    3This result is available only when the option to Perform venting analysis is selected in the solver parameters.
    4This result is only available if a short shot occurs during the analysis.
    5This result is only shown when Abaqus is used for the analysis
    6In order to calculate this result, the wire sweep calculation must be performed in Autodesk Simulation Moldflow Insight.
    7In order to calculate this result, the analysis sequence must include Wire Sweep, and the wire sweep calculation must be performed in Autodesk Simulation Moldflow Insight.
    11 If you select a material with fiber or filler content, Fiber orientation analysis results also will be generated for a Fill+Pack analysis sequence. The option to perform Fiber orientation analysis if fiber material is enabled by default in the Process Settings Wizard.
