Compile Property Data Command
Applicability: Cranium, Synapse

The Compile Property Data command is found on the Chemicals chapter's Commands menu.

The command will activate the Compile Property Values dialog that can be used to compile all values for a selected physical property. This range of these compiled values is useful for checking a new datum entry or establishing the limits of a physical property design constraint.

Compile critical temperature data
  1. Open the MKS Sample KB document and change to the Chemicals chapter.
  2. Select the Compile Property Data command from the chapter's Commands menu. The application will activate the Compile Property Values Dialog.
  3. Select Critical Temperature as the property and Data Only as the Status.

    Optionally you can set limits on the values to compile. For example, if you wished to compile only those values near 500K, you might enter a constraint of 500 ± 25 K. The dialog would compile all chemicals whose critical temperature was between 475K and 525K.

    Similarly you can set limits on the state variables of temperature and pressure dependent properties. For example, if you wished to compile all vapor pressure values near 25°C, you might enter a constraint of 25 ± 5 °C.

  4. Press the dialog's Compile button. The application will begin compiling values displaying its progress in the Progress dialog. When the compilation is complete, the application will activate the Compiled Property Values dialog.
  5. The dialog's Compiled Property Values dialog display all the values found in the current document. A histogram of these values is displayed in the dialog's lower left corner. Several summary statistics are displayed the in the dialog's lower right corner.

    Click the left mouse button on one of the Compiled Property Values valued rows. The dialog will indicate the location of that value in the histogram with a blue diamond within the graph's axis.

  6. Click the left mouse button in the left-most bar of the histogram The dialog will move those values to the top of the table and highlight them.
  7. Press the Ignore button. The dialog will ignore these values in the table (their rows in the table will be grayed-out), remove the values from the histogram and recalculate the summary statistics.
