Modernized design optimization with AI surrogates, streamlined resource management and enhanced simulation integration
This blog outlines how the latest release from Simcenter HEEDS 2604 accelerates design optimization workflows for engineers working with high frequency electromagnetic simulations, CFD, and multidisciplinary optimization – delivering faster compute resource management, AI-powered surrogates, and enhanced simulation integrations.
Compute resource management reimagined
Optimization projects often demand significant computational resources. Managing remote devices, schedulers, cloud services, and local execution a tedious effort – until now.
The new resource catalog
Simcenter HEEDS 2604 reworks the user experience for distributed execution by revamping remote execution capabilities into a new Resource Catalog that transforms how you manage and deploy compute resources:
One-click resource creation: Set up any resource type with a just a few clicks.
Managed catalogs: Download pre-configured managed resources from Simcenter HEEDS Connect for immediate use, or customize them by copying to your local catalog and modifying locked configurations.
Multiple submission items: Create multiple submission items on the same device using direct submission, PBS, LSF, SLURM, MSHPC, or custom schedulers – all with automatically configured default parameters.
Pre-configured job templates for Rescale: Leverage Rescale’s cloud computing power with pre-configured job template IDs that Simcenter HEEDS clones automatically.
Easy resource access: Select pre-defined resources directly from the Process tab, with smart filtering to show only resources with portal-specific properties.
Persistent configuration: Mapped local and remote drives mean you don’t have to redefine paths again – your resource configuration carries across all your Simcenter HEEDS projects.
The payoff? No more tedious resource reconfiguration. Deploy analyses across diverse computing environments with confidence and consistency.
Resource usage optimization for non-optimization studies
Fast running analyses in design of experiments studies can fill up resources and consume significant disk space. Simcenter HEEDS 2604 allows for the option of enhanced control over resource allocation during the execution of DOE, Robustness and Reliability, and Evaluation Only studies. The new resource allocation option helps you balance computational efficiency with disk space management based on your study’s specific needs:
Opt-in resource control: Prevent non-optimization studies from unexpectedly consuming excessive storage and execution resources.
A modernized Neural Network builder with enhanced capabilities
Simcenter HEEDS 2604 introduces a modernized Neural Network builder within Simcenter HEEDS POST that makes AI-powered surrogates faster to train and seamless to integrate into optimization workflows.
Explore the enhanced Neural Network Builder
Simcenter HEEDS 2604 delivers a modernized Neural Network builder. Here’s what’s new:
GPU-accelerated training: Significantly reduce model training time with GPU acceleration – enabling faster surrogate model development for optimization workflows
Automatic early stopping: Prevent overfitting as the system automatically stops training as soon as your model converges.
Seamless workflow integration: Export your trained neural networks to your optimization workflow with a single click.
ONNX format compatibility: Models are automatically saved in ONNX format for maximum compatibility and portability.
Easy comparison and extension: Save, evaluate, and compare your trained models with other surrogates in Simcenter HEEDS POST effortlessly. Need to refine your model? Simply extend or continue training without starting from scratch.
Engineers can now easily replace computationally expensive analyses with accurate neural network surrogates, speeding up optimization cycles while maintaining the fidelity their designs demand.
Monitor the convergence of your multi-objective study
Designing products with competing objectives is always a challenge. How do you know if your multi-objective Pareto optimization is actually converging? How do you know when feasible solutions have emerged? And what if you need to justify additional computational budget to your stakeholders?
Introducing the Pareto convergence plot
Simcenter HEEDS 2604 introduces the Pareto convergence plot, a powerful new run-time analytics feature that transforms how you monitor multi-objective studies. Track convergence behavior during the optimization run and make informed decisions on the fly.
Key capabilities include:
Convergence monitoring: Track the evolution of Pareto solutions across optimization cycles to assess convergence effectiveness and determine if additional computational budget is justified – all while the study is running.
Feasibility detection: See exactly when feasible solutions emerge.
Monitor the convergence of your multi-objective studies, eliminating guesswork, and enabling smarter optimization budget allocation decisions.
End-to-end automated Altair Feko analysis and optimization
Simcenter HEEDS 2604 introduces a set of brand-new Altair Feko portals which deliver comprehensive optimization capabilities for high-frequency electromagnetic simulations:
Integrated workflow: Set up complete CADFEKO, Feko Solver, and POSTFEKO processes directly within Simcenter HEEDS, with the capability to run each portal on a separate compute resource thereby streamlining turnaround time.
Rich visualization: Get deeper insights with comprehensive visualization files for detailed results analysis.
Interactive data exploration: Leverage Simcenter HEEDS-specific plot formats with hover-over data points for detailed, interactive insights into your optimization results.
Now Altair Feko users can optimize antennas, RF components, and other high-frequency electromagnetic devices easily.
Enhanced Ansys Fluent and Fluent Meshing Portals
For engineers working with Ansys Fluent, Simcenter HEEDS 2604 brings significant enhancements powered by the Fluent’s Python API. The new and improved Fluent integration includes:
Streamlined design process: Conduct geometry modifications, remeshing, and mesh/zone replacement all within a robust, parametric framework.
Integrated geometry and meshing: Move from geometry to CFD simulation in one cohesive workflow.
Use the new Fluent portals to execute complete parametric design-to-CFD workflows.
