Available when Capture Curvature is set to Yes, Curvature Min Size is the minimum size returned to the mesher. Some element sizes may be smaller than this based on local feature sizes or other geometric anomalies.
Specify a positive value or accept the default, which is determined by the size factor preferences (Mechanical Min Size Factor, Explicit Min Size Factor and/or CFD Min Size Factor) specified in the Options dialog box. If you retain the default Curvature Min Size and subsequently modify the Element Size , the default Curvature Min Size is recalculated to reflect the size factor preferences.
Note:
The appropriate size factor is based on the physics preference. The Mechanical Min Size Factor applies when physics preference is Mechanical, Electromagnetics. The CFD Min Size Factor applies when physics preference is CFD. The Explicit Min Size Factor applies when the physics preference is Explicit.
When Capture Proximity is also set to Yes, you can specify a global Proximity Min Size to be used in proximity calculations in addition to the global Curvature Min Size. When only Capture Proximity is selected, only Proximity Min Size is available. Refer to Proximity Min Size for details.
