2D Circle
Use the 2D Circle node () to add 2D extra dimension as a circle.
To add a 2D Circle under Definitions Library right-click the Extra Dimensions node and choose 2D Circle from the context menu.
See 1D Interval for the Parameters and Extra Dimension Specification settings.
Circle
Enter a radius for the circle in the Radius field.
Under Position, enter values for the circle’s center coordinates in the x and y fields.
Under Object type, choose Solid or Curve from the Type list for a filled circle or a circle as a curve only.
Under Element size parameters, enter values for the following element-size parameters:
•
The Maximum element size
•
The Minimum element size
•
The Maximum element growth rate
•
The Curvature factor
•
The Resolution of narrow regions
See the documentation in the COMSOL Multiphysics Reference Manual for the Size node in a meshing sequence for more information about these parameters.
