Computational Fluid Dynamics Simulation

Simcenter provides industry leading computational fluid dynamics (CFD) software for fast, accurate simulation of almost any engineering problem that involves the fluids, structures and all of the associated physics.

The real-world performance of your product depends on how it interacts with fluids, either gases, liquids or a combination of both. From designers to CFD engineers to researchers, Simcenter CFD simulation software allows you to predict the most complex fluid dynamics problems virtually and turn these insights into product innovation.

Fluid Dynamics


The computational fluid dynamics (CFD) capability in Simcenter offers an efficient and accurate set of fluid dynamics models and solvers with excellent parallel performance and scalability. It provides a solid foundation for multidisciplinary design exploration.

Multiphase Flow Simulation


Accurately representing the physical behavior of the different fluid and solid phases is key to capturing the real-world performance of your product. Simcenter offers a variety of both Eulerian and Lagrangian modeling capabilities to suit your multiphase flow simulation software needs.

Moving Objects


Within a single CFD software environment, Simcenter empowers users to simulate not only a broad range of physics but also a broad range of body and mesh motions to accurately capture your physics. With our motion models for CFD simulations, you can simulate real-world performance of moving, overlapping objects with overset meshing, predict dynamic 6-DOF motion of bodies, understand multi-physics interactions to model performance ‘as installed’, easily drive geometric changes for design exploration, easily predict rotating/translating machine behavior and define sophisticated motions to accurately replicate machine operations.

Electronics Cooling


Thermal design of electronics is critical to developing reliable products that meet cost and performance goals. With increasing complexity, miniaturization, and higher power density, engineers must predict temperature and fluid flow accurately and evaluate cooling from early development stages to design efficient thermal management solutions for heat dissipation.

The Simcenter portfolio includes leading computational fluid dynamics software with specific electronics cooling simulation capabilities for chip package level, PCB, rack and enclosures to large datacenters. Simcenter supports faster time to market, eliminating board re-spins and reducing prototyping costs, for air and liquid cooled electronics by modeling convection, conduction, radiation and solar loading. Simcenter thermal test solutions support package thermal model calibration to achieve highest accuracy.

Battery Simulation


Digitally validate Li-ion cell design including geometrical cell specifications and cell performance with battery CFD simulation. Extensive components of a battery cell are available, as well as a material database to support the user in model development using CFD analysis.

Power Electronics Thermal Management


Power electronics technology drives innovation in vehicle electrification, energy conversion, and beyond. Thermal reliability and lifetime of power semiconductor devices are affected by peak operating temperatures, temperature cycling, and temperature gradients within the device.

Simcenter simulation software and thermal test solutions hardware provide a unique, comprehensive solution to address thermal management design and reliability assessment. A package thermal model automatically calibrated using a thermal transient measurement performed via electrical test method enables prediction of the junction temperature response to a known high accuracy. Using a calibrated simulation model, engineers can better optimize module and system-level thermal designs, and more accurately predict temperature vs power for an operational mission profile.

Fluid-Structure Interaction


Almost all real-world engineering problems ultimately depend on the interaction between fluids and solid structures. Simcenter STAR-CCM+ offers both finite volume (FV)-based computational fluid dynamics and finite element (FE)-based computational solid mechanics (CSM) in an easy-to-use single integrated user interface. 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.

Particle-Flow Integration


The discrete element method (DEM) can be used to simulate the motion of a large number of interacting discrete objects (particles), such as the granular flow of aggregates, food particles, metal powders, tablets and capsules, and wheat or grass. Simcenter is the first commercial engineering simulation tool to include a DEM capability that is fully coupled with numerical flow simulation.
