We are surrounded by sounds, some pleasant, and quite a few that are not. In order for a product to be accepted by customers, manufacturers must pay close attention to its acoustic signature, both for branding purposes and to limit noise pollution. Engineers must also consider the noise regulations that govern their industry, prior to product release. Problems identified late in development cycle can lead to costly rework and a delayed product launch.
To improve the performance of the products, engineers need to understand the roles of noise sources and all the possible transmission paths. Because of the large domain of the model, it is critical to have efficient solvers and robust technology that can account for the interactions between structures and fluids. The finite and infinite element based technology from MSC Software is intuitive and easy to implement because of the familiar technology of FEA. It is also easier to couple with structural finite element analysis codes, helping you solve coupled interaction between structures and fluids.
Few applications where acoustic modeling are performed are interior & exterior vehicle acoustics, Powertrain, engine components, HVAC ducts, fans & pumps, electrical motors, mufflers, tire noise, silencers, etc.

Vehicle Thermal Management Maturity stages
Important Technologies in vehicle thermal management
We provide heat transfer solutions for engineering and industrial equipment through CFD simulation. The goal is to provide engineers in assessing the thermal compatibility and performance of the devices. Knowing the information on heating and cooling of the associated flow field, design engineers can improve the thermal management of the product significantly. Our analysts reduce the development time significantly by providing key insights through heat transfer studies so that modifications in the design can be applied well before production, providing significant cost and time savings.
Using, Cradle CFD engineers provide insights on cooling system for automobiles and help in improving the design of radiators as well as improve the efficiency of air conditioning system by simulating the air flow and associated temperature inside the cabin.
For industrial equipment such as heat exchangers, heat sinks, burners and boilers, our simulation solutions help design engineers to predict thermal compatibility and heat transfer characteristics through conjugate heat transfer studies.
Engineered Composites have actually been in use for thousands of years. Adobe bricks were made using a composite of mud and straw. It is the combination of the physical properties of each material that gives the composite material many of its physical characteristics. Today’s advanced composites, like carbon fiber, bring together combined properties we’ve come to know – lightweight, strong, durable and heat-resistant. Today, the benefits of components and products designed and produced in composite materials – instead of metals, such as aluminum and steel – are well recognized by many industries.
MSC Software’s extensive solution capabilities in composites help to analyze and enhance complex composite designs. The tools offered by MSC are ideal for numerous types of composites, namely, advanced composites, sandwich panels, plastics, nano composites, hard metals and more.
Product design and development requires that engineers consider trade-offs between product attributes in the areas of cost, weight, manufacturability, quality, and performance. Engineers are faced with the difficult challenge of determining how to arrive at the best overall design, making the right compromises, and not sacrificing critical attributes like safety.
MSC Software offers a complete set of solutions for optimization, ranging from use of gradient based optimization methods, like sizing, shape and topology optimizations, or calculation of response surfaces, to a broader process management to analyze and optimize designs across multiple disciplines. These solutions can be integrated with third party optimizers as well to provide you solutions that mold to your requirements.
One of the most challenging tasks of design and development process is prediction of failure over time. Without knowledge of how a structure might fail, it is harder to improve its safety performance. Physical testing for all possible failure scenarios can be cost prohibitive. Durability analysis from finite element models is becoming increasingly accepted in the design process. The analysis is no longer limited to fatigue life calculations - output can now include safe working stresses, warranty claim curves, and the effects of high temperatures, manufacturing processes and assembly stresses.
MSC Software offers a range of solutions for FE based durability and fatigue problems that enable accurate prediction of product life under any combination of time-dependent or frequency-dependent loading conditions.
Our advanced motion analysis products enable engineers to easily simulate and test virtual prototypes of mechanical systems in a fraction of the time and cost required for physical build and test.
A multibody dynamic (MBD) system is one that consists of solid bodies, or links, that are connected to each other by joints that restrict their relative motion. The study of MBD is the analysis of how mechanism systems move under the influence of forces, also known as forward dynamics. A study of the inverse problem, i.e. what forces are necessary to make the mechanical system move in a specific manner is known as inverse dynamics.
Different types of motion analysis like Rigid and flexible multi body systems, vehicular cornering, steering, quasi-static, coupled control analysis etc, can be performed.
Improve the acoustic performance of your products with the multidisciplinary approach of N&V studies
NVH (Noise, Vibration and Harshness) or N&V (Noise and Vibration), this problem is one of the most often directly perceived quality traits of a product, and is therefore one of the most sought after targets for performance by the product development team to help differentiate themselves from competition.
With leading FEA and MBD (multi body dynamics) capabilities from MSC, users can simulate and predict how a component or system will vibrate under varying operating conditions; for example how a driver or passenger of a car driving down the road can perceive the engine sound at cruising speed or under acceleration and at the same time perceive the feel and the noise generated as the car runs over a pot hole. Some examples of noise & vibration analysis include wind noise, exhaust, fan, interior cabin, engine, suspension etc .
All physical processes are inherently nonlinear to a certain extent. For example, when you stretch a rubber band, it gets harder to pull as the deflection increases; or when you flex a paper clip, permanent deformation is achieved. Several common every day applications like these exhibit either large deformations and/or inelastic material behavior. Failure to account for nonlinear behavior can lead to product failures, safety issues, and unnecessary cost to product manufacturers.
Nonlinear response could be caused by any of several characteristics of a system, like large deformations and strains, material behavior or the effect of contact or other boundary condition nonlinearities. In reality many structures exhibit combinations of these various nonlinearities. MSC Software provides solutions to help you simulate accurately and efficiently systems with any or all of the nonlinearities, with applications encompassing multiple industries.
Industrial use cases include brakes, suspension, welding, riveting, sealing, sheet metal forming, landing gear, tire, exhaust systems, wing structures, etc
The original promise of CAE was to eliminate physical prototypes and tests, yet nearly 50 years into the journey physical prototypes are still key milestones in almost every design program. The reason why comes down to confidence; many engineers and their management simply don’t trust that they get reliable results using CAE. Simulation technology is not the problem; most companies have demonstrated that when best practices are followed, results are consistent and correlate well with the physical world. Inconsistency in the application of CAE technology leads to variability in results.
Automation is the key to improving consistency. In manufacturing, automation was the key to improving product quality – and it will be in CAE as well. At the same time, automation cannot discourage creativity or compromise flexibility; CAE engineers need to be able to exercise professional judgement.
MSC Software provides tools for automation of CAE processes that capture knowledge and best practices, and can be used to automate any step in the simulation process, even across multiple disciplines. Our interactive environment for authoring best practice “templates” is easy to learn & use for everyone from casual user to expert analyst. Our templates are also flexible, allowing the end user to execute them step-by-step, fully automated, or anything in between.
The field of Rotor Dynamics is concerned with study of dynamic and stability characteristics of the rotating machinery and plays an important role in the improving safety and performance of the entire systems that they are part of.
As the rotational velocity of an object increases, its level of vibration often passes through a ‘critical speed’, commonly excited by unbalance of the rotating structure. If the amplitude of vibration at these critical speeds is excessive, catastrophic failure can occur. Internal makeup of turbomachinery can lead to such instabilities, which need to be understood to avoid catastrophic failure during operation. Engineers who design large rotors are challenged to design safe rotating machinery using physical prototypes and tests alone because of high costs and time requirements.
MSC Nastran Rotor Dynamics provides a highly accurate and reliable rotor dynamics solution that enables engineers to simulate the behavior of rotating machinery. Using MSC Nastran, engineers are able to predict critical speed and evaluate the effects of instabilities on virtual prototypes, saving time and money while improving safety.
Increased use of simulation in product design and development has enabled companies identify problems early in the design cycle, and helped drive innovation at a lower cost. At the same time, simulation use has led to creation of enormous amount of data, which is not optimally stored for reuse in future, leading to increased cost in data maintenance and recovery. More than any other engineering process, simulation generates significant amount of data, which needs to be maintained and retrieved efficiently in order to gain full benefit from simulation. Simulation data is one of the most important assets to be managed, as it plays a key role in design decision making process.
MSC Software offers a process and data management solution that is uniquely tuned to address simulation requirements. The system is designed to handle the volume and complexity of the simulation data for FEA, CFD and other computationally intensive methods that are growing by orders of magnitude. The web-based capabilities of SimManager ensure faster deployments, easy extension into new domains and broad scale usability.
Most of the products we rely on today are actually mechatronic systems comprised of mechanical components; pneumatic, hydraulic or electrical control subsystems; and electronic control units. Engineering these complex systems is a true multidiscipline design challenge that is often not fully tested and validated until late in the product development process, leading to costly design changes.
Traditional "build & test" methods and isolated tools for the virtual prototyping of mechanical, electrical, or controls systems neglect important interactions between disciplines, leading to incomplete or inaccurate results. MSC's multidiscipline simulation solutions allow engineers to validate and optimize complete mechatronic system performance, improve product quality, and save time and money by avoiding late design changes.
MSC Software provides a family of high performance solutions for FEA that meet the needs of experienced experts and designers, new engineers, and everyone in between. These solutions help companies meet their business challenges by helping engineers gain deeper insight in their products through virtual testing. Engineers using MSC's structural analysis programs are able to evaluate many different types of designs, giving high confidence that the final design will successfully meet prescribed requirements before the physical product is built.
From single components to large complex systems, from linear static to highly non-linear dynamic problems, MSC's structural analysis capabilities are built to grow with your business, optimize your cost of ownership, and support you in achieving your goals.
MSC’s thermal simulation solutions enable you to model thermal responses including all the modes of heat transfer, namely conduction, convection and radiation. Radiation view factors, critical for radiated energy flow calculations can be computed internally or imported from third party vendors providing options to our users. Additionally, both material properties and boundary conditions could be varied based on local temperatures, and can be modeled accurately and elegantly within MSC’s products.
The objective of a thermal study is often to understand the response and performance of a structure. Based on the modeling needs, chained or coupled analysis can be performed by engineers to study temperature variations and effects on structural behavior, both in terms of the stress response and failure. The multi-physics capabilities that involve thermal response can be extended further to include Joule heating and electromagnetic effects for a better representation of physical behavior.
