The competition for the design and manufacturing of the best-in-class automotive products is more intense than ever due to technological advances and increased customer expectations. As a result, companies across the automotive industry are looking for innovations to improve their product design and manufacturing cycle time, cost and quality, and CAE simulation innovations and their effective implementations have long been proven to be a key competitive advantage. CAE organizations are also facing pressure to become more competitive and efficient. CAE Management and technical experts must constantly address an ever-growing demand to deliver more analytical product design and manufacturing evaluations with little or no headcount increase, thus driving them to create and deploy more automated and simplified CAE methods, tools and processes. Many steps in the “end-to-end” simulation processes in using the commercially available CAE tools have been streamlined or automated, with the notable exception of post-processing and report generation. Today, post-processing & report generation are time-consuming due to the involvements of various manual processes and manipulations, and it consumes about 15-25% of highly skilled FEA analyst's time and yet often yields low-fidelity 2D reports to be shared. The purpose of this paper is to explore and demonstrate how CAE report automation using VCollab® - a report automation tool - and its associated 3D "Digital CAE Reports" will enable CAE analysts to speed up and streamline the way they process and share simulation results with the product design and manufacturing stakeholders. In addition, as compared to traditional 2D CAE reports, 3D "Digital CAE Reports" will allow CAE analysts to share a richer, clearer, interactive and animated report to enable engineers and the management to make better and more confident design and manufacturing decisions.

Integrating simulation within a PLM-based digital thread is an essential step toward modernizing engineering processes, interacting with comprehensive virtual environments, increasing customer/vendor engagement, improving threat response timelines, fostering new technology, reducing documentation cost, and achieving sustainment affordability. While traditional simulations, built manually and residing on local workstations, benefit from perceived advantages in model setup time and results generation, they rarely digitally enrich or become enriched by the enterprise engineering functions around them. MIT Lincoln Laboratory has undertaken an initiative to digitally transform our mission-critical PLM enterprise to include integrated simulation that connects requirements to systems models, engineering data, fabrication and V&V. A primary goal is to demonstrate the cumulative time savings experienced by all users of simulation models and the performance prediction data they produce, over the project lifetime. Secondly, this platform will lay the groundwork for significant growth in the digital domain in the coming years, including real-time multi-objective requirements development with customer organizations as well as simulation-informed MBSE-based trade studies. Finally, with both simulation and source data readily accessible from the digital thread, the entire product team can visualize full process traceability, audit revision synchronicity and rapidly execute on critical program decisions. To accomplish this, we have employed an extensible, low-code PLM platform and automation templates. The content of the digital thread is highly customized to our needs, allowing us to manage source data and models to comply with organization-specific policies. This level of customization is especially important in non-production prototyping environments like ours, as programs require different balances between fully-informed Digital Twins and rapid fabrication schedules. Additional challenges include extreme diversity in our technology pipeline and unique, mission-critical processes between programs. We will discuss multiple simulation workflows, presented in context with their digital thread, as well as the benefits future capabilities such as artificial intelligence can bring to the PLM user experience.

We introduce a web-based platform (CAE-web) for CAE attribute leaders, CAE engineers, and design engineers in automotive R&D. The aim is to aid problem-solving and reduce the time in the development phase. The concept is a web-oriented user interface that enables project members from different teams to access the CAE results, understand the design performance limitations, or compare simulations. In the traditional workflow, design engineers and attribute leaders rely on CAE engineer reporting. This static reporting restricts the independent exploration of the data. The limitation arises from the company's dependency on available software and the required skills to use CAE tools. In the current workflow, multi-disciplinary collaboration is more ensured only if the attribute leader has CAE expertise or the design engineer has a background with that discipline requirement. Such a lack of multi-disciplinary collaboration degrades efficient problem-solving. Moreover, CAE model size limits the number of simulations that a CAE engineer can simultaneously load in post-processing software. CAE-web suggests the idea of multi-disciplinary collaboration by utilizing the advantages of web standards that make it "use it without how to". Consequently, we propose a platform that auto-generates and organizes results in a middle level and presents it as a web page on the company server. CAE-web envisions document segmentation, where it is connecting simulation results to attribute requirements and design limitations. The interconnection of documents will increase the learning rate between different disciplines. Another remarkable advantage is the availability of an additional tool for simulation comparison besides the post-processing tool. As an example, we will present a summary of an industrial implementation for pedestrian analysis. The number of simulations increases enormously for each design in pedestrian analysis. We will illustrate how CAE-web visualizes this big data. The visualization provides two groups of visualization: zoom-out and zoom-in views. Zoom-out views consider the assessment of many simulations, for example, development trees, status tables of safety performance, or embedded results from machine learning. However, zoom-in views contain single/multiple simulation assessments and comparisons. Additionally, the user has a multi-view functionality to combine zoom-in and zoom-out views. In multi-view, zoom-out views are selection inputs for updating zoom-in views.
