Supports are used to represent parts that are not present in the model but are interacting with it. Supports help truncate the domain, which helps in efficiently obtaining numerically accurate results without modeling parts of the geometry that are not of primary interest. There are different types of support available, among which is choosing the appropriate support. This is essential as it assures that the simulation model will properly represent the boundary condition. This video will help you to understand the different support types so you can determine which to use for different situations.
