Unit System

On the Units system tab you can select a system of units from the Units database for both input and output (results).

By default, you do not have to enter unit symbols because the system assumes that you enter all values in the selected unit system. You can also enter data in other units and unit systems that are available in the Units database: Flow Simulation will automatically convert the numerical values to your selected system. In this case you must type the other unit system symbols in the input fields.

The selected system of units has no influence on the general SOLIDWORKS system of units used for creating models.

Prior to running the Wizard, you can check the Units database and, if necessary, define your own unit system in the Engineering Database dialog (see “Engineering Database” for details).

After passing through the Wizard, you can adjust the selected project system of units in the Units dialog (see “Units” for details).

Procedure

  1. Select a unit system from the following pre-defined unit systems:

    • CGS – centimeter-gram-second;

    • FPS – foot-pound-second;

    • IPS – inch-pound-second;

    • NMM – Newton-millimeter-kilogram-second;

    • SI – International System of units: Newton-meter-kilogram-second;

    • USA – foot-pound-second (pressure – pound/inch2 or psi, volume flow rate – foot3/min or CFM).

    Note:

    The unit system selected by default is defined under Unit Options in the Options dialog (see “Options” for details).

  2. If no default unit system suits your needs, select the system which most closely matches your unit system and adjust the selected unit system. The modified system becomes default for the current project but is not saved in the Engineering Database.
  3. If you want to save the modified unit system in the Engineering Database:
    1. Select Create new option;
    2. In the Name box type the name of the new system of units.

    The new unit system will be added to the Engineering Database after you exit the Wizard by clicking Finish.

  4. Click Next or click a button on the Navigator pane to switch to the corresponding dialog box of the Wizard.
