6.4.2.3. Geo Cylinder

A Geo Cylinder Contact generates a force between a geometry and the other cylinder. The geometry can be a rigid body or a flexible body and they can have any kind of shapes. This is a derived concept for Geo Surface contact and it is possible to switch to Geo Surface contact. In the case of action cylinder geometry, it can be analyzed more quickly and accurately than Geo Surface contact.

Note

In Geo Cylinder Contact, only rolling face in Cylinder geometry is considered when calculating contact force.

6.4.2.3.1. Modeling Options

In the case of Geo Cylinder contact, a cylinder geometry type is supported for an action geometry. Solid, shell, and surface geometry types are supported about rigid body and patch set is supported about flexible body for a base geometry when creating.
