Tutorial: Gravity Tilt Pouring Casting

Step through setup and defining the rotation for a gravity tilt pouring casting simulation.

Model file is available in the tutorial_models folder in the installation directory in Program Files\Altair\2024\InspireCast2024\tutorial_models\Tilt-Pour.x_b.

Import Geometry

  1. Launch Inspire Cast.
  2. Click Open Model on the Files icon and browse to the tutorial model file in the installation directory, or drag-and-drop the file into the modeling window.


Designate a Casting Part

Select casting geometries with the Cast Part tool.
Important: A cast part must be defined before performing any other operation.
  1. On the Cast Part icon, click Designate Casting Part.
  2. Left-click to select which candidate is a cast part.
    Parts are automatically detected and highlighted based on your cursor position.
    The selected part is highlighted red.
  3. In the microdialog, select Aluminum as the material, AC-42100 as the alloy, and enter 718 C as the initial temperature for the part.
  4. Right-click and mouse through the check mark to exit, or double-right-click.

Set Gravity Direction

  1. On the Cast Part tool, click Set Gravity Direction.

  2. Confirm that the part is correctly aligned with gravity.


  3. Right-click and mouse through the check mark to exit, or double-right-click.

Set the Ingate

  1. On the the Gate icon, click Designate Surfaces as Gates.

  2. Select a surface to generate a gate.


  3. Thre is no need to check any of the checkboxes in the microdialog. Leave them unchecked.
  4. Right-click and mouse through the check mark to exit, or double-right-click.

Add a Mold

  1. Click the Components tool.

    Click the Add/Edit Mold tool in the secondary tool group.


  2. Select 12343 for the material and enter 150 C for the initial temperature.


  3. Right-click and mouse through the check mark to exit, or double-right-click.

Define Process Parameters

  1. Click the icon next to the Basic Setup icon, then select the Gravity icon.
  2. Select Filling Time and enter 10 s.


  3. Select Tilt Pouring. In the microdialog, use the Move Rotation Axis tool to change the rotation axis from global X to global Y. Change the angle of rotation to 90 degrees and change the rotation time to 4 seconds.


Run Analysis

  1. On the Analysis icon, click Run Analysis.
  2. Use the default values for Average Thickness and Element size.
  3. Select Run a filling analysis and Run a solidification analysis.
  4. Click Run.
    Note: Once the simulation calculation is finished, the green flag will appear on the analyze icon.

    Note: The user can also select the results by clicking View Now under Run History.


Analyze Results

  1. Click Filling under Stage.
  2. Click Temperature under Result Types.


  3. Click the Play button on the video controls to start the animation.

    The part fills smoothly and uniformly with no temperature problems.



  4. Click Solidification under Stage.
  5. Click Porosity under Result Types.


    We can see that the location of the defect is in the filling system and not in the part itself.
