Many turbomachinery applications utilize fluid film bearings to support the rotor during operation, including gas and steam turbines. Utilizing fluid-structure interaction (FSI) simulation provides an attractive option for understanding the performance of the fluid film bearing as flow mechanics, deformation and rotor displacement all play an important role. In this webinar, we will demonstrate how to setup an FSI bearing model with Ansys CFX and Mechanical. We will also evaluate methods to stabilize the rotor position during the FSI simulation, compare each option’s relative computational cost, and demonstrate best practices for setting up fluid film bearing FSI models.

Why FSI Modeling in Ansys CFX & Ansys Mechanical?
Ansys’ tightly coupled CFX–Mechanical workflow brings fluid-structure interaction (FSI modeling) within easy reach, letting engineers simulate the true interplay between flow mechanics, bearing deformation, and rotor displacement in a single environment. Advanced coupling algorithms capture transient pressure fluctuations and structural stresses simultaneously, so you can predict stability thresholds, lift-off behavior, and bearing film thickness with confidence without cobbling together multiple tools or guessing at interface loads.
