Scale
Use the Scale node () to scale the properties of Attributes nodes, as shown in Figure 8-99. It is possible to add Scale nodes both as global nodes and as local nodes to Reference nodes. A Scale attribute that exists as a global node affects the size of the mesh elements generated by the subsequent operation nodes. A Scale attribute that exists as a subnode to a Reference node affects the size of the mesh elements generated by the Reference node only.
Figure 8-99: Tetrahedral mesh built with the predefined size Normal (left). Scaling the element size on the selected domains (blue) by 0.5.
If two or more Scale nodes exist on the same selection, the resulting scale factor on that selection is the product of the given scale factors.
To add Scale () as a global node, choose one of the following:
Click Sizing () in The Mesh Toolbar and select Scale ().
Right-click the Mesh node and select Scale ().
To add Scale () as a subnode, right-click a Reference node and select Scale.
Then use following sections to specify the scaling properties:
Geometric Scope
In this section you define the geometric entities where you want to specify a scale. Choose the level of the geometry from the Geometric entity level list.
Choose Entire geometry to specify the scale for the entire geometry.
Choose Domain, Boundary, Edge (3D), or Point (2D and 3D) to specify the domains, boundaries, edges, or points for which you want to refine the mesh. Choose Manual from the Selection list to select the domains, boundaries, edges, or points in the Graphics window, choose a named selection to refer to a previously defined selection, or choose All domains, All boundaries, All edges, or All Points to select all domains, all boundaries, all edges, or all points, respectively.
Scale
Specify the scale factor in the Element size scale field.
A scale factor less than 1 gives smaller (more) elements; a scale greater than 1 gives larger (fewer) elements.
