Creating Surface Mass Densities

Surface masses are distributed as mass per unit area over the selected geometry.

Surface masses can be applied to surfaces, faces, or surface groups.

This task shows you how to create a surface mass on geometry.

  1. Click the Surface Mass Density icon .

    The Surface Mass Density dialog box appears, and a Surface Mass Density object appears in the specification tree under the Masses objects set for the current analysis case.

  2. You can change the identifier of the mass by editing the Name field.

  3. Select the geometry support (faces of shell geometry). Any selectable geometry is highlighted when you pass the cursor over it. You can also select a face group. You can select several supports to distribute the mass over all supports simultaneously.

    The Supports field is updated to reflect your selection.

  4. Enter the mass per unit area in the Surface Mass Density field.

  5. Click OK in the Surface Mass Density dialog box.

    Symbols representing the applied mass are displayed on the geometry.
