Overview
Simcenter HEEDS accelerates the product development process by automating analysis workflows, maximizing available computational hardware and software resources and efficiently exploring the design space to identify innovative solutions while assessing performance and robustness.

Main benefits

• Design Space Exploration
  Facilitates efficient exploration and optimization of design options and parameters within the design space, enabling engineers to achieve superior results with greater ease and effectiveness.
• Time and Cost Efficiency
  Automates the design process and leverages optimization algorithms to reduce the time and cost associated with product development by rapidly evaluating many design variations.
• Multidisciplinary Optimization
  Supports simultaneous consideration of multiple engineering disciplines for a holistic approach that captures interactions across domains.
• Workflow Automation
  Automates repetitive tasks in design and optimization, streamlining workflows and enabling faster decision-making and more comprehensive exploration.

What's new (Simcenter HEEDS 2504)
Simcenter HEEDS 2504 streamlines surrogate modeling, enhances data-mining and visualization tools, accelerates workflows via automation and AI-enhanced search, and maintains seamless integration with existing and new portals. Key aims include modeling complexity more easily, exploring possibilities faster, and tighter integration with portals and toolchains.

Process automation
Simcenter HEEDS integrates with many commercial CAD and CAE tools without the need for custom scripting. Key capabilities include:

• Creating process flows that combine internal, commercial 1D/2D/3D simulation and cost-estimating tools
• Modifying native geometry and robustly re-meshing or updating physics models
• Supporting co-simulation or sequential workflows
• Automating model rebuilding to explore broad design spaces

Distributed execution
Simcenter HEEDS leverages all available compute resources (Windows and Linux workstations, on-premise clusters, HPC, and cloud). Distributed execution features include:

• Use of all computing resources (local, remote, clusters, cloud)
• Multiple levels of parallelization: workflows, tasks and cores
• Support for unlimited load cases and orchestration across platforms/OS
• Integration with licensing schemes, HPCs and cloud resources to maximize throughput
• 24/7 run availability for large-scale exploration

Efficient search (SHERPA)
Simcenter HEEDS implements Simultaneous Hybrid Exploration that is Robust, Progressive, and Adaptive (SHERPA): a hybrid, adaptive search approach that does not require model simplification or surrogate fitting. It combines multiple global and local search strategies, adapts as it learns about the design space and identifies high-performing families of designs with fewer simulations, reducing time, cost and design risk.

AI-enhanced search (AI Simulation Predictor)
AI Simulation Predictor augments SHERPA to accelerate searches for computationally expensive CAE analyses. It provides accuracy-aware AI within the hybrid-adaptive search framework to learn and improve searches and to reuse prior data. Benefits include significant reductions in optimization time (up to ~40% reduction in compute time reported for lengthy optimizations) while maintaining comparable results and enabling faster discovery of improved designs without requiring AI expertise.

Insight and discovery
Simcenter HEEDS provides visualization and data-mining tools that help teams compare performance across broad design domains, identify families of top-performing designs, evaluate sensitivity to input variables, and assess robustness to manufacturing tolerances—supporting informed design reviews and decisions.

Main use cases

• Automated virtual prototyping and process automation
• Multidisciplinary design optimization and trade-off analysis
• Large-scale distributed simulation orchestration (HPC and cloud)
