Creating Pressures

You can create a pressure applied to surface geometries. Pressures are intensive loads representing uniform scalar pressure fields applied to surface geometries, and characterized by the fact that the force direction is everywhere normal to the surface.

Units are pressure units (N/m2 in SI).

Before you begin: A structural analysis simulation containing a load set must be open.

  1. In the Loads toolbar, click Pressure .

    The Pressure dialog box appears.

  2. Optional: In the Name box, modify the name of the load.

  3. Select the geometrical support to which you want to apply the pressure.

    See Authorized Supports.

    Tip: You can select several supports in sequence to apply the pressure specification to all supports simultaneously. Any selectable geometry is highlighted when you pass the cursor over it.

    Several arrows symbolizing the pressure are displayed.

  4. In the Pressure box, enter a scalar value of pressure.

    Tip: A positive value describes a pressure whose resultant is directed towards the material side of the selected surface.

  5. Optional: If you want to import pre-defined data, select the Data mapping check box.

    To learn more about the data mapping option, see Using Data Mapping.

    Important: The availability of this option depends on your available licenses. See Licensing.

  6. Click OK.

    The pressure is created, and Pressure.1 appears in the specification tree both under the excitation library and the scenario.
