Creating Geometric Groups

You can create geometric groups. Geometric groups allow you to group elements based on a selection of geometries (points, lines, surfaces). You can create groups in a dedicated set or create group under a mesh.

Before you begin: A mesh must exist for groups under a mesh.

  1. To create a group in the Groups set, click Geometric Group in the Groups toolbar. To create a group under an existing mesh, right-click the mesh in the specification tree and select Create Group > Geometric Group.

    The Geometric Group dialog box appears.

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

  3. Select the geometries (points, lines or faces) to create a group. You can select geometries in sequence and your first selection conditions the type of group you create.

    • To create a group of nodes, select geometric points.
    • To create a group of element edges or a group of 1D elements, select geometric lines.
    • To create a group of element faces or a group of 2D elements, select geometric faces.

  4. Click Apply to create and update the group.

  5. Click OK.

    The geometric group is created, and Geometric Group.1 appears in the specification tree under the Groups set.

    If you created a group directly under an existing mesh, the geometric group is stored under the mesh in the Nodes and Elements set.
