Contact analysis is a numerical method used to understand and predict physical phenomena that occur when two or more objects contact or interact with each other.
When objects come into contact with each other, they transfer forces to each other. This force exerts pressure on the touching surfaces and, in some cases, creates friction.
The purpose of contact analysis is to understand how these pressure and friction forces affect the behavior and properties of an object.
Today, I will perform contact analysis using hypermesh based on the youtube video below.

The key to contact analysis with HyperMesh is to accurately define the contact surface.
Make sure you know exactly which side you want to contact, inside or outside.
Create - Group
SSID(Secondary Sruface ID) : This is used to identify the 'secondary surface' or 'slave surface' of a contact pair. The SSID indicates the finer-grained side of the contact, usually the side composed of smaller elements.
MSID(Main Surface ID) : This is used to identify the "dominant surface" or "master surface" of a contact pair. The MSID indicates the rougher side of the contact, usually the side composed of larger elements.
Using HyperMesh, it was relatively simple to implement a nonlinear contact analysis.
