/INTER/TYPE14 - Interface Type 14 - Ellipsoidal Surfaces to Node Contact

Description

This interface simulates impacts between a hyper-ellipsoidal rigid master surface and a list of slave nodes. The hyper-ellipsoidal surface is treated as an analytical surface (hyper-ellipsoidal surfaces are only discretized for post-processing). For this interface, generally, use a mesh whose size is finer than the lowest semi- axis of master surface. The master surface must be a Madymo hyper-ellipsoidal surface or a RADIOSS hyper-ellipsoidal surface.
