When specifying component mesh control, you can specify a uniform element size for the selected components, or you can use a relative size that is interpreted based on individual components.
The relative size interpolates a different element size for each selected component based on the selected position on the slider. The left end of the slider corresponds to the default global element size of the assembly (G). The right end of the slider is different for different components. For each component, it corresponds to the default element size if the component is meshed independently as a part (Ci). Using (Ci) to mesh a component generates 4000 to 6000 elements in most cases.
The program calculates the element size (Ei) for component i from the equation:
Ei = G - (G-Ci) f
Where (f) refers to the selected position on the slider with f = 0 at the left end and 1.0 at the right end. This equation calculates smaller element sizes for smaller components as (G) is always greater than (Ci). The above relation can be represented graphically by the next figure.

Smaller part (i.e., smaller Ci) is meshed with smaller element size (i.e., smaller Ei) |
Larger part is meshed with larger element size |
