3D Sphere
Use the 3D Sphere node () to add 3D extra dimension as a sphere.
To add a 3D Sphere under Definitions Library, right-click the Extra Dimensions node and choose 3D Sphere from the context menu.
See 1D Interval for the Parameters and Extra Dimension Specification settings.
Sphere
Enter a radius for the circle in the Radius field.
Under Position, enter values for the sphere’s center coordinates in the x, y, and z fields.
Under Object type, choose Solid or Surface from the Type list for a filled sphere or a sphere as a surface 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.
