Agentic Engineering: How AI Agents Can Accelerate Advanced Modeling and Simulation Workflows

The promise of automation in engineering has always been compelling: reduce repetitive work, accelerate project timelines, and free engineers to focus on innovation rather than logistics. Yet despite years of advances in process automation and generative AI more recently, engineering teams have been bottlenecked by manual tasks. However, this is rapidly changing with the rise of agentic engineering: an approach driven by the combination of AI-powered systems that solve complex reasoning tasks, use specialized tools, and execute sequential actions to accomplish human-specified objectives. Unlike conversational AI assistants that only provide responses or recommendations, agents can take action while adapting to the variation inherent in engineering workflows.

Engineering teams and practitioners are increasingly adopting agentic approaches to deliver rigorous accuracy, consistent adherence to specific methodologies, and the flexibility to accommodate variation that drives innovation. An engineer exploring a new design space needs the freedom to adjust parameters, test alternative approaches, and follow unexpected insights. This exploration and variation are what drive innovation and breakthroughs. 

As agentic AI gains momentum across forward-thinking enterprises, agents specifically built for modeling and simulation teams are demonstrating early wins and big potential to supercharge productivity. Specialized and embedded agents have the potential to be game-changing for R&D activities from everyday gains in speed and productivity to the ability to explore more design possibilities. Business leaders also expect AI in R&D to drive meaningful business impact, such as 20% lower R&D costs and 10-20% reduction in time to market (BCG). 

The Unique Challenges of Building Agents for Digital Engineering Workflows

Before understanding what agentic automation brings to engineering, it’s worth examining how agents solve shortcomings of traditional automation approaches.

Most engineering workflows involve a series of interconnected tasks: preparing input data, configuring simulation parameters, running analyses, post-processing results, comparing outputs against requirements, and documenting findings, often while consulting extensive test reports, modeling guidelines, and requirements documents. Each step may be straightforward, but the specific sequence, the parameters chosen, and the decision points along the way vary based on what the engineer discovers at each stage.

Consider a structural analysis workflow. An engineer might start with an initial finite element  mesh, run an analysis, examine the resulting stress field, and then decide whether to refine the mesh in specific areas, adjust boundary conditions, or tune certain solver settings. This adaptive and iterative decision-making is central to effective engineering work.

Traditional automation methods handle this variation poorly. They require either rigid, predetermined workflows that limit exploration, or deterministic manual configuration for each new scenario. This is often hard to maintain or requires software engineering skills most domain experts might not have. More problematically, institutional knowledge becomes trapped in these rigid systems. When a senior engineer changes teams or leaves the company, their accumulated expertise often leaves with them. New engineers must rebuild and rediscover these insights through trial and error, adding unnecessary duplication of effort and hurdles that delay project timelines. 

Agentic Engineering for Simulation and Modeling

Intelligent agents represent a transformative approach to engineering automation. Rather than pre-scripting exact sequences of steps, agentic systems understand the intent behind a workflow and can adapt their execution based on intermediate results, available tools, and learned patterns from previous work. In the context of simulation and modeling workflows, agentic automation means systems that can:

• Understand Engineering Intent: Instead of following rigid step-by-step instructions, agents interpret high-level goals (like “optimize this thermal design” or “validate structural performance”) and determine the appropriate sequence of actions needed to achieve them.
• Adapt in Real-Time: When intermediate results suggest a different approach would be more effective (poor mesh convergence, unexpected stress concentrations), agents can adjust their execution path without requiring engineer intervention or workflow reconfiguration.
• Execute Parallel Workflows: Agents orchestrate multiple concurrent workstreams that would traditionally run serially, enabling engineers to explore branched simulations across design variants and test conditions simultaneously. This parallel execution compresses design space exploration from weeks to days.
• Capture and Apply Expertise: Agents learn from previous workflows, incorporating best practices and organizational knowledge (optimal mesh settings, validated initial and boundary conditions and solver settings) into their execution logic.
• Orchestrate Multiple Tools: Rather than operating within a single application, agents coordinate actions across simulation software, CAD systems, pre/post-processing tools, data repositories, analysis platforms, and documentation systems.
• Preserve Human Oversight: Critically, agents work alongside engineers rather than replacing them. They handle routine execution (setup, submission, data transfer) while flagging decision points that require engineering judgment (design trade-offs, results validation).
• Maintain Organizational Policies: Agents can follow enterprise governance frameworks with organizations defining access controls, execution parameters, and approval requirements. This ensures agents operate within established security policies and compliance requirements while preserving audit logs for regulatory traceability.

The agentic approach preserves the variation and flexibility that engineering workflows require while automating the time-consuming aspects that bog down productivity. A common need in engineering automation is maintaining methods and ensuring accuracy. Agentic engineering addresses this by operating at two distinct levels. For technical calculations and analyses, agents invoke deterministic engineering tools—validated solvers, established analysis methods, certified calculation procedures—ensuring results meet engineering rigor standards. For workflow orchestration and logistical tasks, agents employ AI reasoning to sequence operations, transfer data, and flag anomalies, with engineers confirming decisions at critical junctures. This hybrid approach preserves engineering accuracy while leveraging AI’s strengths in contextual understanding and reasoning.

Orchestrating Engineering Workflows with MCP

The recent development enabling agentic automation in engineering is the Model Context Protocol (MCP), an open standard that allows large language models to interact directly with engineering tools and systems. Prior to MCP, AI systems could reason about engineering workflows and provide recommendations, but executing actions required bespoke integrations tightly coupled to specific platforms.

MCP changes this by providing a standardized way for AI agents to discover available tools, understand their capabilities, and invoke them with appropriate parameters. When an engineer instructs an agent to “run a thermal analysis on this design and compare results against the previous iteration,” the agent’s reasoning engine determines the required steps to identify the relevant simulation tools, locate the necessary input files, configure and execute the analysis, and compile the comparison. MCP provides the common protocol that allows those tools to be discovered and invoked without the need to configure custom integrations or requiring engineers to script each individual step.

Importantly, MCP is not proprietary to any single platform. It enables agents to orchestrate workflows that span multiple tools, from commercial simulation tools, general-purpose LLMs, to custom analysis scripts. Rescale offers an MCP server that connects the ecosystem of AI and agentic tools, enabling actions to be handed off to specialized sub-agents and tools across an organization’s technology stack. This interoperability is crucial for engineering teams who rely on diverse toolchains and need automation that works seamlessly across current and future workflows.

Practical Opportunities for Agentic Automation

The practical implementation of agentic automation in engineering workflows typically involves several layers of capability:

• Workflow Capture and Standardization: Rather than requiring upfront process definition, agentic systems observe how engineers actually work (CFD setup sequences, mesh generation patterns, solver configurations), identifying patterns and recurring sequences. Over time, these observations become reusable workflow templates that can be invoked by simple instructions rather than manual re-creation.
• Intelligent Task Decomposition: When given a high-level objective, agents break it down into executable subtasks (geometry preparation, meshing, solver setup, post-processing), selecting appropriate tools and sequencing them logically based on learned patterns and engineering methodology.
• Dynamic Execution and Error Handling: As workflows execute, agents monitor intermediate results (convergence behavior, mesh quality metrics, solver stability), detect anomalies or failures, and can adjust execution strategy or alert engineers when human judgment is needed.
• Knowledge Integration: Agents incorporate domain-specific engineering knowledge such as design guidelines, validation criteria (requirements, convergence thresholds, safety factors), and regulatory requirements, ensuring that automated workflows maintain quality and compliance standards.
• Continuous Learning: Each workflow execution provides data that refines the agent’s understanding of effective patterns (optimal solver settings, mesh refinement strategies, time step configurations), common failure modes, and optimization opportunities.

Agentic automation adapts to how engineers actually work, learning from their patterns and decisions. Institutional knowledge becomes encoded in workflow templates that remain accessible to the entire organization, preserving expertise as engineers move between projects or teams.

Perspective for Leaders Driving Agentic Initiatives

Leaders overseeing R&D and product development organizations will find that agentic automation presents both critical implementation considerations and potential business impact. As organizations navigate this evolving landscape, several strategic factors are worth keeping in mind:

Implementation Considerations

• Bottom-Up Standardization: Instead of imposing process standards that may not fit actual engineering work, agentic systems enable standardization to emerge organically from observed patterns. Focus on empowering engineers to maintain flexibility while the organization gains visibility into common workflows and best practices.
• Process Intelligence and Traceability: Because agentic systems orchestrate and document workflow execution, leaders should seek insight into how engineering work actually happens. This provides the foundation for evidence-based process improvement and regulatory traceability without imposing burdensome documentation requirements on engineering teams.
• Testing and Governance Frameworks: Because agents operate autonomously and produce non-deterministic results, organizations need systematic testing methodologies to ensure accuracy and effectiveness. This requires establishing evaluation frameworks that assess whether agents use appropriate tools correctly, align their reasoning with engineering methodology, and meet quality standards. 

Business Impact 

• Scalable Productivity Gains: Traditional automation delivers linear improvements. Agentic automation scales differently by executing multiple workflows in parallel, enabling engineers to explore dozens of design variations simultaneously. The same workflow logic deploys across teams, transforming sequential, weeks-long design space exploration into concurrent analyses delivering results in days.
• Preserved Engineering Focus: Perhaps most importantly, agentic automation shifts engineering time from logistical tasks to substantive technical decisions. Engineers spend less time preparing datasets, configuring simulation parameters, and transferring results between tools, and more time interpreting findings, exploring alternatives, and making design decisions.
• Accelerated Decision-Making: By automating the execution of routine analyses and comparisons, agentic systems compress the time from question to answer. This acceleration compounds across a project lifecycle, enabling teams to explore more design alternatives and iterate more rapidly toward optimal solutions.

Getting Started with Agentic Engineering

Implementing agentic engineering effectively demands a different mindset than traditional automation initiatives. Success depends less on top-down process redesign and more on providing engineering teams with tools that allow them to capture and scale their own expertise.

This means investing in platforms that support agentic capabilities, encouraging engineers to document and share workflow patterns, and accepting that the most effective automation may look different across teams working on different problems. It means measuring success not by workflow standardization metrics common to business process automation, but by engineering outcomes: faster project delivery, more design alternatives explored, fewer errors in execution, and ultimately better products brought to market more quickly.

Modern AI capabilities combined with agentic automation make it possible to gain the benefits of automation without sacrificing the flexibility that makes engineering work effective, while agents learn from individual engineers’ work patterns to build personalized workflows and dynamic interfaces that streamline repeated tasks. The variation and exploration of engineering workflows are defining features of engineering innovation that can now be captured, scaled, and personalized, with productivity gains compounding as the system becomes more efficient over time.
