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\2021\InspireCast2021\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.


  3. Use the mouse and view controls to position the model.

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 and the first alloy, A356, 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 surface to generate one.


  3. 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 and enter 150 C.


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

Define Process Parameters

  1. Click the Casting tab.
  2. Click to select the Gravity icon.
  3. Select Filling Time and enter 10 s.
  4. Select Tilt Pouring and select Y as Rotation Axis.


  5. Click Select to choose Rotation point then click the point on the geometry to define it.


  6. Enter the following values for Time and Angle in the Rotation table.
    Time (s) Angle (deg)
    0.0 90.0
    2.0 70.0
    4.0 50.0
    6.0 30.0
    8.0 10.0
    10.0 0.0

Run Analysis

  1. On the Analysis icon, click Run Analysis.
  2. Select Run filling analysis and Run solidification analysis.
  3. Enter an Average Thickness of 0.55 mm.
  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 Play to start the animation.

    The part is filling smoothly and uniformly with no issues with temperature.



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


  6. Click Play to start the animation.

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