Dassault Systèmes’ 3DEXPERIENCE: A Progressive Approach to Modeling and Simulation

In a recent post, we discussed the challenges associated with a traditional approach to simulation where engineers and analysts work in silos using unintegrated tools. When team members can’t collaborate effectively, companies must contend with inaccurate or incomplete data that cause delays and increased costs. In order to address these issues, companies need to take a more integrated approach to modeling and simulation. Dassault Systèmes’ 3DEXPERIENCE platform provides a solution to the disjointed and disconnected workflows by offering product development teams an integrated and collaborative modeling and simulation environment.

Design Process using 3DEXPERIENCE Integrated Modeling and Simulation 

Dassault Systèmes’ 3DEXPERIENCE platform provides an integrated set of modeling and simulations tools that directly addresses the challenges of the traditional approach to simulation. The 3DEXPERIENCE platform  enables seamless collaboration between design engineers and analysts, leading to better efficiency.  In this post, we will outline the 3DEXPERIENCE approach to modeling and simulation and discuss the platform’s benefits for:

  • analysts who perform multiple simulations,
  • design engineers who must navigate elaborate design iterations, and
  • simulation artifact management.

3DEXPERIENCE’s Approach for Analysts  

3DEXPERIENCE platform makes the process of preparing for simulation much more efficient. Here’s how it works for designers.

When a design engineer completes a design or revision, the 3DEXPERIENCE platform can notify the analyst. The platform maintains one design model—a single source of the truth—so there is no risk of working with an outdated version of a design. 

Analysts using the 3DEXPERIENCE platform use intelligent, automated tools to convert elaborate design models to simplified simulation models. The two models are connected in the system, so when the design model changes, the 3DEXPERIENCE platform automatically updates the simplified model to match. This is a direct contrast to the disjointed traditional approach where analysts must perform updates manually. Thus, the 3DEXPERIENCE platform keeps the engineer’s design work and the analyst’s simulation work in sync.

Analysts apply loads and boundary conditions to the model to proceed with their simulation. These conditions are then associated with the design model geometry. If the design changes, analyst’s don’t need to reapply loads and boundary conditions. This improves their workflow and saves time.

Using the simulation model built with the 3DEXPERIENCE platform, an analyst is able to accurately solve their simulation, regardless of whether an engineer issues a design change because any changes are automatically propagated to the simulation. Simulation modeling is carried out directly within the platform, eliminating the need for analysts to transfer the design from one solution to another, which, once again, improves the workflow of the analysts, enabling them to focus on the task of evaluating the design’s performance characteristics.

3DEXPERIENCE Supports the Design Change Process

When an analyst comes across a flaw or shortcoming in the design, they can notify the design team through the 3DEXPERIENCE platform. Using the notes from the analyst, design engineers make changes to the original design. Because the simulation model has associativity with the design model, it automatically updates. In this way, the majority of the design changes are automatically applied to the simulation model without manual effort or building a new simulation model from scratch. Because analysts do not need to remesh their model or reapply loads and boundary conditions, their modeling workload is reduced whenever design changes are introduced.

The connection between the analysts and the design engineers is entirely through the 3DEXPERIENCE platform, and both groups are able to communicate through the platform to keep the other apprised of any necessary changes to be made or changes that have been made, with any changes being automatically incorporated via the platform.  This is another way in which the 3DEXPERIENCE platform enables design teams and analysts to reduce the number of steps in the workflow as they communicate with each other during the design phase.

Since design of products often require simulations in different physics domains, the platform allows individual analysts to develop their own simulation models, each tied back to the original design model. This makes it possible for an entire analysis team to simultaneously evaluate multiple design requirements. As each analyst performs their individual simulation and reports any need for design updates to the design team, those updates will be propagated to every simulation model built by the analysis team. This allows analysts to perform new simulation on the updated design without any need to manually setup the simulation model again. 

3DEXPERIENCE Platform Manages Simulation Artifacts

Another reality of employing simulation early in design is the explosion in the number of simulation models and results. For each iteration of the design model, there is an equivalent simulation model and set of results in each physics domain. So, one design model produces a simulation model and results for structures, fluid dynamics, excitation, thermodynamics, and more. The more models there are, the more artifacts there are. As a result, the number of artifacts produced by using simulation early grows extremely fast.

The traditional methods for managing these artifacts and tracking which design iteration corresponds to each one have inherent flaws. It is easy to lose track. This results in errors, decisions made against the wrong information, and time wasted by both engineers and analysts.

The good news, however, is that the 3DEXPERIENCE platform provides automated tracking of these artifacts. By incorporating any design changes into a single source of truth for the overall design, the platform keeps track of any changes and associated simulation artifacts like setup data, result files, and communications. These artifacts are made available to both the design engineers and analysts as they work to optimize the overall design. Since any design update and the associated artifacts are made available to all stakeholders in the design and analysis process, there is no need for anyone to install additional software to keep track of the artifacts or design updates. This provides all parties with immediate access to design changes or requests for updates, all from within the 3DEXPERIENCE platform.

This intuitive connection across multiple disciplines of a product development team enables more efficient sharing of ideas and information. As analysts request updates based on their individual simulation and engineers implement those updates, all members of the design team and the analysis team enjoy real-time access to the simulation artifacts and associated modeling updates.

Conclusion

Using the Dassault Systèmes’ 3DEXPERIENCE platform, product design teams can more effectively perform engineering modeling and simulation. The platform enables analysts to quickly build a simulation model based on a single design truth and propagate required design changes back to the design engineers directly. When engineers make those changes, the platform updates the simulation models to reflect the changes. The result is a collaborative environment where engineers and analysts can work together more efficiently. Finally, all stakeholders in a design workflow can track and evaluate simulation artifacts, reducing the time spent on these key tasks.

The 3DEXPERIENCE platform helps organizations improve collaboration and efficiency for product design, modeling, and simulation. It boosts their ability to solve complex design challenges quickly. Then, engineers and analysts can focus on successfully meeting the needs of customers rather than working on syncing the CAD model and the associated simulation models multiple times during the design process. In the end, they are better positioned to provide customers with effective product engineering solutions.
