Scale
Use a Scale node () to scale the properties of the Size, Distribution, and Boundary Layer Properties nodes. It is possible to add Scale nodes both as global nodes and as local nodes to Reference nodes. A Scale node that exists as a global node affects the size of the mesh elements generated by the subsequent operation nodes. A Scale node that exists as a subnode to a Reference node affects the size of the mesh elements generated by the Reference node only.
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 this as a global node, in the Mesh toolbar from the Modify menu, select Scale ().
•
To add this as a subnode, right-click a Reference node and select Scale. See also Global vs. Local Attributes.
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 to specify the domains for the scale specification. Choose Manual from the Selection list to select the domains in the Graphics window or choose All domains to select all domains.
•
Choose Boundary to specify the boundaries for the scale specification. Choose Manual from the Selection list to select the boundaries in the Graphics window or choose All boundaries to select all boundaries.
•
Choose Edge to specify the edges for the scale specification. Choose Manual from the Selection list to select the edges in the Graphics window or choose All edges to select all edges. This option is only available in 3D.
•
Choose Point to specify the points for the scale specification. Choose Manual from the Selection list to select the points in the Graphics window or choose All points to select all points. This option is only available in 2D and 3D.
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.
It is not possible to use a coarser mesh size setting on a geometric entity adjacent to a higher dimensional entity with a finer mesh size setting; the finer setting on a geometric entity overrides the coarser setting on its boundary. Therefore a scale factor larger than 1 might have no effect if the dimensional level of the selection is less than the space dimension.
