Supporting common fluids, structural, and thermal simulation applications, it allows engineers to experiment with design ideas and see instant feedback from their chang-es. It therefore radically lessens the need for persistent, laborious testing on expensive physical prototypes and consequently cuts the total develop-ment time and cost. Additive ManufacturingThe design engineer today needs to build optimized, lighter and smarter products to stay relevant. With ad-ditive manufacturing, the process of manufacturing itself can introduce changes in the final shape, and sim-ulation can help to factor in those changes. Therefore, there is a need to use appropriate tools like 3D De-sign products that enable CAD mod-eling and simulation for all design engineers. Simulation tools are today built on direct modeling technolo-gy that makes creating, repairing or editing geometry easy, whether you are involved in concept modeling, reverse engineering scanned data or preparing a model for manufacturing or simulation.Digital Twin and SimulationDuring operation, to fully compre-hend a machine, the comprehensive virtual model must be connected to actual operational data from the ma-chine. The virtual model is the digi-tal twin. Digital twins eliminate the silos, errors inadequacies, doubts and enormous resources while working with models. Engineering simulation forms a key component of the digital twin. When simulation is added to the dig-ital twin system, environments that are otherwise difficult to view and evaluate becomes evident. The prod-uct performance can be maximized by scheduling predictive mainte-nance, determining root of perfor-mance issues, and evaluating various other aspects. Simulation allows ac-curate prediction of how the changes in machines will affect it during its life cycle. Simulation is thus the lone method to completely appreciate the digital twin technology.On-Product Simulation From cars, airplanes and trains to consumer electronics, machinery and healthcare solutions, products have been transformed through simulation. Product simulation observed sin-gle characteristics: one physics, one component, one design. Now we ex-plore multiple designs at the system level with interactions across several physical and digital realms. Simu-lation is being utilized not only for design validation, but also from ear-ly ideation through manufacturing, operations and maintenance.We are thus viewing an ultimate revolution in engineering and prod-uct development. The advantages of simulation when in vehicles are well-known. As on-track testing is expen-sive and not always feasible, simu-lation is what makes design changes easier and makes it a reality. Autonomous cars, for example, have to be out on the open road and be able to adapt to all the uncertain-ties that come along with it. It has to have the ability to do this on par with or even better than humans in order to be considered safe. What is required is over 8 billion miles of test driving. How does a company do so much testing? The only solution is simulation if one is hopeful of releas-ing them anytime soon. The valida-tion of the software that is needed by the manufacturers can be done only in this manner. If one depends exclusively on AI for autonomous cars then one won't be able to assign or trace the neural networks of AI to safety require-ments. Simulation actually trains and tests artificial intelligence. The safety gates of autonomous car developers are what decide if the outputs of the AI system disrupt any safety stan-dards. If positive, then it initiates a course of action based on a safety plan. This system needs to be validat-ed and the only way to do that in less time is through simulation.There is a seamless integration of design and simulation for all engi-neers now that help them to explore ideas and concepts in greater depth. It provides a single platform for sim-ulation-driven product development. The technology is easy to learn and use and offers unparalleled adaptabil-ity, speed and accuracy to enhance the final design. Simulation is thus the shortest route between design and reality and it helps companies in bringing innovative and safer prod-ucts into the market faster. Simulation solutions involving any area of physics, be it structures, fluids, electronics or combinations of these, will provide engineers with the speed that is needed to stick to these goals that seem to be almost impossible to reach
