Mesh Control dialog box–Fillet density type options

Selection
Select Targets	Lets you select a hole or connected loop of edges on which to define a Fillet type of density.
Filter	Select the Filter option to have the software search your model for fillet surfaces that meet the specified Fillet Selection Parameters.
Fillet Selection Parameters
Minimum Radius./Maximum Radius	Lets you control the size of the fillets that the software selects automatically by specifying a minimum and maximum radius. The software ignores any fillets whose radius is smaller than the Minimum Radius value and larger than the Maximum Radius value.
Minimum Angle./Maximum Angle	Lets you control the size of the fillets that the software selects automatically by specifying a minimum and maximum angle. A fillet’s angle is the angle between the faces that the fillet connects. The software ignores any fillets whose radius is smaller than the Minimum Angle value and larger than the Maximum Angle value.
Type	Lets you specify the type of fillets that you want to select.Select All Types to have the software identify faces with either inside or outside radii within the specified Minimum Radius and Maximum Radius values.Select Inside Radius to have the software identify faces with inside radii within the specified Minimum Radius and Maximum Radius values.Select Outside Radius to have the software identify faces with outside radii within the specified Minimum Radius and Maximum Radius values.
Preview Fillets	Displays the fillets that meet the specified criteria.
Mesh Parameters****Along Axis
Mesh Density By	Controls how you define the spacing of the elements along the length of the filletSelect None if you do not want to control the spacing of the elements along the axis of the fillet. If you select None, the software uses the global mesh size to generate the elements along the axis during meshing.Select By Size if you want to specify the size of elements along the axis of the fillet. Enter a target element size in the Element Size box.
On Circumference
Density by	Controls how you define the spacing of the elements around the circumference of the fillet.Select None if you do not want to control the spacing of the elements around the circumference of the fillet. If you select None, the software uses the global mesh size to generate the elements around the circumference of the fillet during meshing.Select By Angle if you want to specify the total number of elements around the circumference of the fillet. Specify the number of elements in the Elements Per 90 deg box.You can specify the number of elements as an integer value, or you can specify the number as an expression. See Expressions for more information.Select By Size if you want to specify the size of elements around the circumference of the fillet. Enter a target element size in the Element Size box.
Minimum Size	Lets you specify the smallest allowable element size around the circumference of the fillet.
Mesh Quality
Aspect Ratio	Lets you specify the aspect ratio value that you want the software to maintain for the elements on the fillet during meshing. If the software cannot maintain the specified aspect ratio value with the specified element size and minimum element size, it reduces the Along Axis element size.
