Dynamics fluid mechanics physics science software

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.

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. Gain insight into the interactions between turbulent flow field and underlying chemistry of reacting flows. Simcenter helps you improve the trade-off between the performance and emissions of your device for different operating conditions. 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. Flow induced noise is a significant component of the acoustic signature of a vehicle or other product. 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.

The chapters of my book may be downloaded free and printed, but cannot be modified or edited. In particular, do not mix material taken from my book with other material.

The use of complete chapters is not only permitted, but also recommended. Thank you. Publication Plan The book is organized in a series of Chapters that should be read sequentially and a series of Appendices that should be consulted when necessary.

The appendices are transversal to the main text, so that you can find in them references to material dealt with in the course of the whole book.

Furthermore, appendices do not aim at being complete and detailed. Many notions are only quoted to inform the reader about the scientific background he needs to be able to understand the main text.

However, the appendices do not limit themselves to quote classical results, but also include considerations and problems that are particularly oriented to the understanding of the fluid dynamics, but cannot be easily found elsewhere. With the exception of the first introductory part, the chapters aim at being as complete as possible, proving all the derived laws with a few exceptions relative to particularly long demonstrations of little physical relevance.

At the end of some chapters and appendices we provide the reader with information about the time and the authors of the main discoveries dealt with in the text, along with recent references to which the reader is addressed to deepen the various topics. They make no pretence to be accurate or complete. They have been introduced especially to stress that this text follows a logical, and not a historical order. The date in front to the chapters refers to the first publication of the material in the context of the relative book.

Later this material can have been corrected, modified, expanded, split in two or moved in another place. In the future other chapters can be inserted between two already published chapters, even if the publication is normally sequential. The same can be repeated for the appendices. For this reason we publish a News page, in order to help the reader in the identification of the new material since his last access.
