  1. Perform the tasks described in the following topics to create a new material and add the Simulation domain to it.
    1. From the Compass, click Material Definition.
    2. From the Material Tools section of the action bar, click Create Material .
    3. In the Title box of the Create Material dialog box, enter a name.

      Note: If you do not enter a name, a default name is given to the material.

    4. Enter 1 in the Core Materials field, and enter 0 in the Covering Materials field.
    5. In the Add domains list, select the simulation domain.
    6. Click OK.
  2. In the tree, right-click the Simulation Domain for the newly created material and select XXX object > Definition.
    The Material Definition: Simulation Domain dialog box appears.
  3. To create a material that represents the polymer that fills the cavity part, you must define the following simulation domain options:
    • Injection Molding: Characteristic Temperature, Plastic Viscosity, PVT
    • Thermal: Conductivity, Specific Heat

    Definition of the Injection Molding Fiber Reinforcement is optional. For a simpler material behavior, you can define Density instead of PVT, and Fluid Viscosity instead of Plastic Viscosity.

  4. To create a material that represents the coolant flowing in a coolant part, you must define the following Simulation Domain options:
    • Density
    • Fluid: Viscosity
    • Thermal: Conductivity, Specific Heat
  5. To create a material that represents the virtual mold, you must define the following Simulation Domain options:
    • Density
    • Thermal: Conductivity, Specific Heat
  6. Click OK.
