To use dynamic defaults:
Retain the default settings of Defeature Size, Curvature Min Size, Proximity Min Size, and/or Max Size.
Note: If you modify any of these default sizes, their values will not update dynamically. This is because user-defined sizes are always retained.
Adjust the Element Size.
In response, the other default global mesh sizes will update dynamically.
(Optional) For more control over global size scaling, modify the values of the Mechanical Min Size Factor, CFD Min Size Factor, Mechanical Defeature Size Factor and/or CFD Defeature Size Factor options to obtain the desired scaling.
(Optional) To control scaling locally, choose Factor of Global Size as the Type when you define a local sizing control. Then, depending on the entities and other options you select for the control, use the Defeature Size Scale, Curvature Min Size Scale, and Proximity Min Size Scale local sizing control options to obtain local sizing based on the global sizing.
Note: By setting Type to Factor of Global Size, you ensure the local sizes will update dynamically if you change the global element size.
