In this video, you can see how the user is able to navigate on the performance map, evaluating the behavior of the design on specific operating conditions, for different values and views (pressure field, velocity field, etc.). Then, the user can upload a new geometry, and get the instantaneous predictions of the model on the whole range of operating conditions.
When issuing a prediction, one can question human or artificial intelligence on how much she/it is sure about the prediction. Without going into detail on the dramatic consequences of overconfident artificial agents in such situations as Autonomous Driving, this article will focus on the Neural Concept’s core competence: building predictive models that are surrogates of more resource-intensive CAE models.

In this blog post, we take a deeper look at the unique capabilities of this new feature and how it allows you to create optimization workflows that are different from every other solution currently in the market.
During new vehicle development the current design is frozen and released and important attributes are analyzed virtually. After such a release, a vast amount of data is available and CAE models need to be created or updated as fast as possible with high quality. The process of collecting, checking and preparing all data was cumbersome and a significant amount of time was also needed to check and correct the received models which could have been based on incorrect input.
The auto industry has been moving from a physical test-based development process to more of a virtual one. All aspects of the vehicle’s design and performance targets are being driven by the use of CAE simulations. Taking the data from one format like CAD and putting them into various formats that physics-based solvers can use is key. Honda R&D America's Mr. Eric Dehoff presents at the 8th BEFORE REALITY Conference.

“Siloed or simulation tool-specific SPDM is simply not scalable with the increasing demands for more and more simulation as part of the overall design process,” contends Pawel Chadzynski, senior director, product marketing at Aras. “When simulation data is in multiple spreadsheets owned by individual experts, you can’t scale up the volume of simulation needed for the complexity of products. You just can’t do it with existing infrastructure.”
This NAFEMS and Rev-Sim co-hosted webinar will help to establish a fundamental understanding of Systems Thinking as a critical complement to the Reductionist design approach. As part of the discussion, we will explore the need for pervasive simulation across the entire product lifecycle as a critical tool for the design, manufacture and maintenance of tomorrow’s interconnected multidisciplinary products.
For simulation to have a broader financial impact on an enterprise, SPDM needs to be implemented and deployed seamlessly within the broader enterprise, especially as required to support implementations of Digital Threads and Digital Twins.

Is this the next major step that is needed in our industry to design, validate and support our products with advanced integrated systems that have been increasing exponentially in complexity?

These objectives can be realized by different ways of working and an IT-infrastructure to allow these processes to become digital and connected.
The vision for Generative Design is that it could enable a significant paradigm shift in the design processes used today by enabling designs to be computer-generated based on a proper specification of rules, requirements, and constraints. This overturns the current practice of design, where designs must first be created so they can be evaluated against their performance requirements.
Generative Design is the use of algorithmic methods to quickly and automatically, or iteratively, transform requirements, constraints, uncertainties, and design space to create/drive viable designs or outcomes. Requirements, constraints, and uncertainties may include factors from multiple areas including: design, performance, manufacturing, usability, aesthetics, ergonomics, and cost.
This presentation introduces approaches and platform characteristics that increase the smoothness of the information flow across domains, and between system designers and simulation engineers, through the realization of a custom, domain-independent, system-centric digital thread. This provides a single source of truth for the specifications of all systems of interest and related data.
A True Digital Twin replicates the proposed physical space, and includes all mechanical, robotic, sensor, vision, AI, and computer systems, while simultaneously incorporating real human action and interaction. Humans experience the system in virtual reality (VR), with concurrent motion capture driving their avatars in real time. The avatars interact with virtual objects and their physical “stand ins”, which are also motion-tracked. All aspects of the system, including hardware, software, AI training data/models, and human interaction, are developed, tested and optimized virtually using a proprietary software platform.

“A Vision for Generative Design” is a software independent intrinSIM market research paper that explores the potential paradigm shift enabled by Generative Design and what is required to enable that design paradigm shift. This market research paper looks at the key capability areas required to support a paradigm shift and proposes a capability assessment model with detailed assessment criteria for each of the key capability areas.
The term “generative design” has been used in architecture and civil engineering for more than a decade. It is now gaining currency in the mechanical design (MCAD) world.
CAD programs are ideal for design engineers who need to express their concepts, whether the shape of an automotive part or the housing of a smartphone, in detailed 3D geometry. Dassault Systèmes’ SolidWorks and CATIA, Autodesk Inventor, Siemens PLM Software’s Solid Edge and PTC’s Creo Parametric exemplify such programs.
In today’s design environment, it’s increasingly necessary to combine multiple file types in a single project. If you need to work with parametric, direct and facet modeling within the same project, some CAD platforms require you to move design data across multiple pieces of software.
Generative design replicates natural world's evolutionary approach with cloud computing to provide thousands of solutions to one engineering problem.
Generative design is opening new opportunities for solving design problems — and turning traditional workflows upside down, moving simulation ahead of model creation. Understanding the basics of the technology can help you decide if it’s time to share your AEC or MCAD workload with generative design tools.
To complement this issue on generative design, Ian Symington, NAFEMS Technical Officer, reached out to members of the NAFEMS Vendor Network nafe.ms/vendor to get their thoughts on the topic.
