Capabilities

Structures Capabilities

Easily handle the complexity of varied design environments with a range of analytical tools that enable you to meet performance goals and ensure long-term reliability.

Blade Design and Optimization

Streamlined workflows with blade design integration to help optimize your design.

Streamline your workflow starting from our blade design tools or software partner offerings, from design to mesh to a robust result. Design tools and optimization methods are integrated into our turbo workflows for the best design improvements.

Aeromechanics

Improve safety of rotating components with accurate aeromechanical simulations.

Early aeromechanical simulations help improve safety and durability of rotating components. Transient blade row (TBR) methods are used to reduce geometry from a full-wheel to a single passage. Problems are solved with time marching or harmonic balance.

Turbulence Modeling

A wide range of turbulence models are available, allowing you to choose the best model for your application. CFX also includes the industry leading Generalized k-ω (GEKO) model. GEKO is a revolutionary concept with tunable coefficients that can be adjusted to different flow regimes.

Subcooled Wall Boiling

Accurately model wall boiling and calculate the critical heat flux using validated models for bubble growth, phase change, drag and non-drag forces.

Advanced Material Modeling

Get the most accurate results with real gas and fluids properties

CFX’s advanced material modeling help generate the most accurate results. Real gas and fluid property tables can be created from the REFPROP database using adaptive methods to efficiently resolve changes in material properties (near critical point, for example). Liquid water and steam properties are selectable from the built-in IAPWS database.
