Problems that involve multiple moving and interacting components can be easily simulated with Simcenter CFD software using overset meshing, mesh morphing, or a combination of both. The moving mesh capabilities can also be used for parametric studies and for steady or unsteady CFD simulations, providing an easy way to reposition or replace objects to study multiple design configurations in your computational fluid dynamics (CFD) simulations.
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 simulation needs.
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.
Computational rheology is used to model non-Newtonian or viscoelastic materials in industrial problems. The rheology solver accurately resolves the dominant physics of complex rheological material flow and helps predict their behavior.
In order to go faster while modeling the complexity of today's products, computational fluid dynamics (CFD) engineers need to be able to choose the best possible method depending on accuracy and turnaround time requirements for a given simulation project. Smoothed-particle hydrodynamics (SPH) is a rapid meshless CFD simulation method that complements conventional mesh-based approaches. Based on the Navier-Stokes equations, the particle-based SPH method in Simcenter is well suited for highly dynamics flows, deformable and complex moving geometries and fluid interfaces with fragmentations/ reconnections.
Flow induced noise is a significant component of the acoustic signature of a vehicle (or other product). Simcenter offers an extensive library of accurate models for predicting aeroacoustics noise sources, including: steady state models, direct models (DES/LES), propagation models and acoustic perturbation equations (APE) solver.
Simcenter supports hybrid aero-acoustic methods in which at first, a CFD simulation is used for capturing flow turbulences, which are translated into aero-acoustic sources to be plugged into a second acoustic (FEM) simulation model. The latter then predicts the acoustic propagation of these sources, including reflections and absorption in the environment. As such, for instance the cooling noise of electronic equipment of the HVAC noise in a car can be predicted.
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.
Couple to other simulation tools through dedicated interfaces, or an intuitive API. This enables the multi-physics simulations with different time scales ranging from microseconds to thousands of seconds, providing faster and more accurate analyses and shorter turnover times for development and assessment of complex designs
Rather than just simulating a single operating point, explore how your product performs over the full range of operating conditions that it will face during its working life, and employ intelligent design exploration to discover better designs faster.
Comprehensive analytical models include all aspects of the design of electric machines, including thermal, electromagnetic and drive control. Of particular importance is the efficient utilization, and even elimination, of magnets. Our simulation tools are structured to give seamless design capability over the entire range of permanent-magnet machines and the alternatives including hybrid combinations and covers the entire range of power, voltage, and speed used in vehicle systems.
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.
Engine simulations involve moving components, multiphase flow, combustion and heat transfer. You no longer have to be an expert user to simulate internal combustion engines: using an application-specific workflow and simplified interface allows you to set up engine simulations quickly and easily. Expert users can use those simulations as the starting point for performing more complicated multiphysics engine simulations that exploit the full range of Simcenter STAR-CCM+ simulation capabilities.
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.
Power electronics technology is driving innovation in vehicle electrification, energy conversion and beyond. Thermal reliability and lifetime of power semiconductor devices is effected 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 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.
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.
