CAE expertise and technical know-how in the aerospace field
Noesim is a design and engineering company founded in 2005, located in Cesatei, Italy, just a few kilometers away from Milan. The purpose of establishing Noesim is to merge the engineering and management skills acquired by the founder during his tenure at various companies in Italy. The company's goal is to provide professional knowledge to organizations that aspire to achieve success through innovation and competitiveness. Noesim's core business is focused on the aerospace industry, while also providing services to companies in other industries that require computer-aided engineering (CAE) expertise and simulation tools during project design validation.

Noesim has established a solid business foundation since its inception, providing engineering consulting services to the aerospace industry. Guglielmo Barbiani, co-founder of Noesim, said, "We have worked in the aerospace industry for many years and have a deep understanding of the needs of various companies in this industry, such as unofficial customs and standards, such as using Nastran as a de facto standard CAE solver. In addition, we also need a CAE tool that is compatible with all the different CAD software packages used by customers. ”

In order to build an efficient and highly competitive organization, Noesim has established internal standards and procedures that are independent of customer processes. By using software tools capable of handling multidisciplinary tasks, Noesim's engineers have developed their core competencies, mastering static and dynamic structural analysis as well as specialized knowledge in the fields of composite materials, kinematics, fluid mechanics, and heat transfer.

Co founder Franco Belloni said, "For us, another key element is quality, which is the realism of CAE simulation. Traditional FEM (Finite Element Modeling) programs and CAE analysis are used to solve linear problems. However, in the real world, nonlinearity is ubiquitous from contact modes to material issues, and then to large displacements. Therefore, the software we need should be able to provide highly realistic simulations, support all analyses, and not be limited to just one domain. ”

Process integration and standardization
Noesim uses Femap from Siemens PLM Software ™ Software and NX ™ Nastran ® The decision of software is also driven by two other factors. The first factor is application cost - namely initial investment cost, total cost of ownership (TCO), and personnel training cost. The second factor is the opportunity to integrate software with downstream simulation operations. In addition to obtaining CAD geometry from clients, Noesim's work process also includes using specific application software or Excel ® Perform calculations using spreadsheet software. Noesim needs a tool that can easily integrate with other application software and Noesim's self-developed accessory modules.

Belloni said, "Considering future development and needs, we were still looking for a tool that could help us establish a clearly defined standardized process, so that we could access CAE data for projects and simulations and validations performed on behalf of clients. In CAD, users usually use prescribed programs and workflows to perform development, validation, and approval work, and all designers follow the same routine, while the difference in CAE process lies in 'personalization'. In this regard, what is useful and interesting to us is that Siemens PLM Software's proposal also includes an advanced data management tool - Teamcenter. ”

Barbiani said, "It's easy to make a decision. We only need to make a small investment to obtain 'Femap+NX Nastran'. Femap+NX Nastran is a Windows based tool that can integrate with other application software for downstream analysis and provide support for different industries. In addition, the software also has multiple CAD integration functions and provides a FEM pre/post processor compatible with other solvers used by customers. ”

Advanced support services
In addition to verifying the functional behavior of customer developed products, Noesim also provides advanced support services to customers. Belloni explained, "We usually start from the product development stage. By obtaining the CAD geometry created by the customer in the preliminary design stage, we can build an FEM model for engineering validation and provide accurate feedback to the customer on the required modifications. Iterating between FEM models and new CAD geometry inevitably requires efficient tools like Femap - which can update individual operations instead of simply repeating them - as well as high-quality solvers like NX Nastran, which reduce the behavioral gap between structures in simulation and the real worldmoreLow level, thereby reducing the prototype cost for customers. ”

In addition, Noesim also develops methods for companies outside of the aerospace industry to help them understand how CAE tools can solve product related problems using a standardized approach. Barbiani said, "For example, we conducted research on the lid of a pressure vessel. By incorporating analysis into the product development process, customers have mastered a method to reduce weight while maintaining the original strength level. Therefore, product designers can directly apply and use these analysis methods, even if they may not have specific experience or advanced technical skills. Our purpose in providing consulting services is to enable customers to independently carry out their work

Wide range of benefits
Due to its extensive configuration and customization features, Femap has proven to bemoreusefulmoreEffective methods for developing tools. Belloni stated, "Femap can be customized and additional tools can be added to automate the entire process of model generation, analysis, computation, and data management. Even small companies like ours that use standard Microsoft applications can use Femap to develop data extraction and management programs. Femap is a Windows based software that can generate files like Excel spreadsheets without the need for import or formatting operations, thereby reducing cycle time; Due to the absence of manual steps that are prone to errors, data reliability is increased. As Femap is a Windows based software, it can fully utilize hardware resources and analyze complex assemblies composed of hundreds of parts without the need for powerful machines. ”

Usability is also important. According to Barbiani, Femap is not only easy to learn but also intuitive and user-friendly due to its familiar configurable interface. He explained, 'It's easy to find instructions when using Femap.'. Even users who have never used CAE tools can easily use Femap. New users, including students from Politecnico di Milano who intern at our company for two to three months each year, highly appreciate this advantage because they can focus on solving engineering problems rather than learning software operations. Compared to other tools they use in college, Femap's functionality is excellent. ”

Barbiani added that excellent technology and sales services are indispensable for high-value "deployment/use" software paradigms, so he is very satisfied with Siemens PLM Software partner Team3D, which has been providing support to Noesim since the initial implementation of Femap.
