55.3. Modeling

The single-sector model of a NASA Rotor 67 fan bladed disk is meshed with SOLID186 elements at default settings:

The disk and blade geometries are meshed separately. A contact pair is created between the blade and disk.

55.3.1. Contact Modeling

A bonded surface-to-surface contact pair (using the MPC-based algorithm) is defined for the contact between disk and fan blade:

The contact surface is meshed with CONTA174 contact elements. The target surface is meshed with TARGE170 target elements.
