Computational fluid dynamics
The real-world performance of many products hinges on their interaction with fluids, whether gases, liquids, or a combination of both. Computational fluid dynamics (CFD) simulations enable the prediction and analysis of flow and heat transfer behaviors. However, given the increasing complexity of modern products, understanding fluid dynamics and heat transfer in isolation is no longer adequate.
To leverage this complexity as a competitive advantage, today's CFD engineers must model a diverse range of fluid-related physics, including reacting flows, aeroacoustics, multiphase flows, particle dynamics, electronics cooling, and aerodynamics.
Our solutions for fluids and thermal simulation empower you to virtually predict the most intricate fluid dynamics challenges, transforming your insights into innovative product designs.
Multiphase flow simulation
Real-world engineering problems encompass multiple flow regimes, such as stratified, dispersed, discrete, and films. Currently, no single multiphase model can cover all these regimes. However, our CFD solutions offer a comprehensive range of models for multiphase CFD simulations, which can be combined to cover many flow regimes, including the transitions between them.
Predict and understand the real-world behavior of your products by simulating multi-regime, multi-scale multiphase flows using hybrid multiphase capabilities of our advanced software.
Particle flows and discrete element method
Particulate flows are ubiquitous in engineering applications, such as fluidized beds, cyclone separators, coating processes, conveyors, and roasters. Whether dealing with lean or dense particle flows, our CFD simulation solutions offer full particle-flow integration to maximize particle efficiency and distribution, minimize energy consumption, reduce excessive wear and abrasion, and optimize overall performance.
By accurately simulating realistic particle shapes with proper motion and contact, engineers can ensure optimal material handling performance. Unlike other tools, our software provides coupled flow and particulate physics within a single simulation environment, significantly reducing simulation setup effort. With both mesh-based and meshfree Discrete Element Methods (DEM), engineers can always select the most suitable particle modeling approach.
Flow analysis
Whether dealing with gases or liquids, our solutions offer a comprehensive set of computational fluid dynamics (CFD) models for single-phase flows. From compressible to incompressible, and from laminar to turbulent flows, our software provides CFD analysis for any flow regime. For turbulent flows, aerodynamics engineers across various industries can select from a state-of-the-art set of turbulence models, including all common Reynolds Average Navier Stokes (RANS) models, Detached Eddy Simulations (DES), and Large Eddy Simulations (LES).
Hypersonic speed is a highly intriguing topic for current research and future commercial flights. In hypersonic regimes, where fluid dissociation and ionization occur, the ideal gas equation of state may not be suitable. Instead, real gas equilibrium may be a more appropriate option.
Reacting flows
Our solutions offer a comprehensive suite of reacting flow and emission models, covering a wide range of applications. They enable tight coupling between reacting flow models and heat transfer, radiation, multiphase reactions, and surface chemistry. Our reacting flow models help you understand and optimize flame shape and location, minimize solid component temperatures, reduce emissions, and maximize performance efficiency.

Heat transfer
Today's innovative products, from electronic devices to mobility solutions, require advanced cooling and thermal management solutions. Our CFD suite enables engineers to accurately and efficiently simulate heat transfer within and between media. With capabilities for conduction, convection, radiation, conjugate heat transfer (CHT), and boiling, our CFD simulation offers a comprehensive suite of heat transfer physics to precisely predict temperature distributions in both fluids and solids.
Our simulation solutions also provide efficient workflows for thermal stress analyses. Thermal engineers can solve heat transfer problems between a fluid and a structure, and subsequently assess thermal stresses in the solid regions.
Fluid-structure interaction (FSI)
Almost all real-world engineering problems ultimately rely on the interaction between fluids and solid structures. Our CFD simulation solutions offer both finite volume (FV)-based computational fluid dynamics and finite element (FE)-based computational solid mechanics (CSM). This integration enables engineers to simulate fluid-structure interaction (FSI) within a single, user-friendly interface and advanced features such as mesh morphing, mesh rotation, mesh motion, 6DOF and DFBI.
Using this approach, you can solve static, quasi-static, and dynamic problems, including those with nonlinear geometry and multiple parts using bonded and small sliding contacts.
Rheology
With computational rheology in our CFD analysis, engineers can simulate fluids dominated by diffusion and viscous or viscoelastic behavior. Computational fluid dynamics of non-Newtonian fluids is particularly useful for engineers in the consumer product, waste processing, and food and beverage industries who work with mixers, flow containers, slurries, extrusions, and material processing.
Accurately simulating rheology is crucial for reducing power consumption, emissions, and raw material usage while enhancing product reliability, user experience, and liability costs.
Electronics cooling simulation
Effective thermal design is essential for developing reliable electronics that meet both cost and performance objectives. As devices become more complex, miniaturized, and power-dense, engineers must accurately predict temperature and fluid flow. Early-stage cooling evaluations are crucial for designing efficient thermal management solutions to dissipate heat.

Aeroacoustics
Flow-induced noise is a significant component of the acoustic signature of a vehicle or other products. Our solutions offer an extensive library of accurate models for predicting aeroacoustic noise sources, including steady-state models, direct models (DES/LES), propagation models, and an acoustic perturbation equations (APE) solver.
Our software support hybrid aeroacoustic methods: initially, a CFD simulation captures flow turbulences, which are then translated into aeroacoustic sources. These sources are integrated into a second acoustic (FEM) simulation model, which predicts the acoustic propagation, including reflections and absorption in the environment. For example, this method can predict the noise from an HVAC system or side mirrors in a car.
