Design Space Exploration

• Process Automation (Automate building of virtual prototype)
• Distributed Execution (Accelerate testing of the virtual prototype)
• Efficient Search (Look for better design alternatives)
• Insight & Discovery (Ensure reliable product performance)

• Illustrate the four technologies of HEEDS working together to yield innovative solutions
• Show that HEEDS can work with any modeling and simulation (CFD, FEA, MBD, etc.) tools

This automated design exploration process can work with any physics and with any of your simulation tools, whether they’re commercial or internal legacy tools. These tools can be 1D, 2D, or 3D and can be based on FEA, CFD, MBD, or any other methodology. You don’t need to change your simulation tools; you just need to connect them together effectively with HEEDS.

Here’s an example of those four enabling technologies of HEEDS applied to automotive bumper design for crash safety.

An automotive component supplier desired to automate the process of exploring bumper design in an effort to identify the lowest mass design which satisfied all design and performance constraints.
Their overall parametric simulation model contained over 60 variables and 9 mandated FEA crash load cases, along with corresponding performance constraints for each load case.

To prove that automated exploration would yield a high return on investment, they embarked on a subset proof-of-concept demonstration that involved 20 design variables and 2 load cases.
HEEDS automated a process involving NX CAD for 3D modeling, LS-DYNA for crash simulation, and Python for model execution and post-processing.

After 100 evaluations across 12 cores, HEEDS discovered a design that reduced overall bumper mass by 32% over the baseline design.
Note that, unlike with previous design exploration techniques, there’s no need with HEEDS to simplify the problem or reduce the number of design variables.  In fact, the more variables that you include, the better chance that you have of finding truly innovative solutions.

Discover Better Designs, Faster – with HEEDS Design Optimization Software

 

 
In order to achieve our goal of helping engineers discover better designs, faster, we re-examined traditional virtual prototyping to identify ways to streamline the process.
In Singapore, most companies are spending more time than they want on model building and less time on improving design performance. Here at Simcenter HEEDS, we’ve invested in creating four enabling technologies to streamline virtual prototyping and drive innovation
 
So, how can we help your engineers to discover better designs, faster?  It requires that we begin to streamline your virtual product development, or “VPD,” process.
Today, most companies begin their VPD process by manually building their virtual prototype simulations by connecting their CAD, CAE, and, perhaps, costing tools. Then, they re-create product operational tests for their virtual prototypes.
 
Once they have confidence in their virtual prototype performance predictions, they try to improve the design by making design modifications manually or with the help of a design of experiments approach. And, finally, they assess the resulting design(s) for robustness before releasing the product for production.

What percentage of your modeling & simulation efforts do you think you spend in each of these phases?

Countless customers tell us that they allocate most of their resources to building and testing their virtual prototypes. But they realize that the greatest value instead comes from understanding and improving their designs.
 
What they want to do is begin to better align their resources with the value received. Siemens is focused on making this possible by providing four enabling technologies to streamline your VPD process.

1. First, we provide process automation capabilities to simplify the virtual prototype build process.
2. Next, we enable better access to distributed execution and parallelization to accelerate virtual prototype testing.
3. Thirdly, and most importantly, we offer the most efficient design search capabilities in the marketplace, without the need for model simplification.
4. Lastly, we make insight and discovery assessments a central part of virtual product development, rather than an afterthought.

These four enablers are the heart of the technology provided by Siemens, through our HEEDS design exploration product.
