Exercise 2: Adding user-defined records

In addition to using records supplied in the Granta Selector databases, you can also add your own data by creating a user-defined record.

New materials are continuously being developed and introduced onto the market. These materials can be added and compared with other materials in the database using the User-Defined Record feature.

When you add user-defined records in Granta Selector, they appear in the Browse tree, under My records. User-defined records are saved in the selection project file, not the database.

  1. In the Selection project you created in the last exercise, add a Limit Stage with the following constraint:
    Thermal expansion coefficient
    < 100 μstrain/°C
  2. Add a user-defined record

    Go to the bubble chart and reset the view, then right-click and select Add Record.

  3. Set the following values for the new record:
    Name:
    New material
    Density:
    Min. 1100 kg/m^3
    Young’s Modulus:
    70 - 75 GPa

    Click OK when finished. The new record will be shown on the Chart Stage in the default color (orange).

  4. View the new record on the chart

    On the Chart toolbar, click Highlight user defined records. All the materials that are not user-defined are grayed out.

    When a record is added from a chart, only the selection attributes are shown for data entry. User-defined records do not fail stages when no value has been entered for a specified constraint (thermal expansion coefficient, in this example).

    To edit or delete a user-defined record, right-click the record in the Browse tree and select the option on the shortcut menu.

  5. Delete the Limit Stage, but keep the initial Chart Stage, as this will be needed for the next exercise
  6. Save the project.
