Running a Transient from production start-up analysis

Run a Transient from production start-up analysis to monitor the flow of heat in the plastic injection mold, from one cycle to the next to determine the number of cycles needed to reach a stable mold temperature.

Note: If you imported a CAD/ STL mold first mesh the part, the feed system and cooling circuit, then mesh the mold.
Note: If you are modeling the mold in Autodesk Simulation Moldflow Insight, first mesh the part, the feed system and cooling circuit, then create a surface mesh for the mold, then create the 3D mesh for the mold.
  1. Import a model.
  2. Import or model the feed system, including the gate, runners and sprue.
    Note: Make sure that the feed system is represented by curves, or it will not be considered in the mold.
    Note: If you import the feed system, make sure you set an injection location.
  3. Import or model the cooling circuit.
    Note: Make sure that the cooling channels are represented by curves, or they will not be considered in the mold.
    Note: If you import the cooling channels, make sure you assign them the property Channel.
  4. Click (Home tab > Molding Process Setup panel > Analysis Sequence) and select a Cool (FEM) sequence.
  5. Select the Transient from production start-up analysis from the Process Settings Wizard - Cool (FEM) Settings dialog.
  6. Select the solver you would like to use from the Cool (FEM) Solver Parameters dialog
  7. Confirm that all steps in the Study Tasks pane, up to Create Mold Mesh, have been completed and have a check mark associated with them, except 3D Mesh.
  8. Import a CAD or STL mold, or click (Geometry tab > Create panel > Mold Surface) to create a mold surface.
    Note: Make sure that all tetrahedral elements are fully enclosed by the mold surface.
  9. Hide the mold layer and click (Mesh tab > Mesh panel > Generate Mesh) to mesh the part, feed system and cooling channels.
  10. If you created a mold surface using Autodesk Simulation Moldflow Insight, show the mold layer and click (Mesh tab > Mesh panel > Generate Mesh) to create a surface mesh for the mold.
    Note: Check the surface mesh for errors and fix any errors before continuing.
  11. With the mold layer visible, click (Mesh tab > Mesh panel > 3D Mold Mesh) to create a 3D mold mesh.
    Note: Check the 3D mold mesh for errors and fix them before continuing.
  12. Click (Home tab > Analysis panel > Start Analysis) to launch the analysis.
