6.4.3.3. Sphere To Cylinder
A Sphere To Cylinder Contact generates a force between a sphere and a cylinder.
The sphere and cylinder must belong to two different bodies.
The sphere must be defined an action geometry and the cylinder must be defined a base geometry.
The sphere must be out of the cylinder.
The contact force can be not only linear or exponential but also nonlinear spline characteristics to the contact penetration and its velocity
6.4.3.3.1. Modeling Options
In the case of Sphere To Cylinder contact, a sphere geometry type is supported for an action geometry and a cylinder geometry type is supported for a base geometry when creating.

Figure 6.357 Properties of SphereToCylinder dialog box
Definition of The Base Cylinder
Entity Name: Defines the name of base cylinder. The base cylinder can be dispatched from the Working Window by clicking Gr.
Radius: Shows the radius of base cylinder.
Length: Shows the length of base cylinder.
Definition of The Action Sphere
Entity Name: Defines the name of action sphere. The action sphere can be dispatched from the Working Window by clicking Gr.
Radius: Shows the radius of an action sphere.
Synchronize with Geometry
If this option is checked, Radius and Length in the contact properties are automatically defined with that of the specified graphic.
If this option is not checked, the user can modify the contact properties.
Force Display: Graphically displays the resultant force vector on the view window.
