Exam Overview: What the Five Domains Cover
The Autodesk Certified Professional in Simulation for Static Stress Analysis (ACP-SIM-STRESS) credential validates a candidate's ability to run a complete static stress simulation workflow inside Autodesk Fusion - from preparing a model to refining results after a first solve. Autodesk organizes this workflow into five sequential content areas, published in the official exam objectives document identified as 091621. Understanding how these domains map onto the real simulation workflow is the fastest way to prioritize your study time and avoid guessing at what "static stress analysis" means on this specific exam.
Unlike open-ended engineering coursework, the ACP-SIM-STRESS exam is scoped tightly to a linear process: get the model ready, configure the simulation study, run the solve, interpret the output, and then refine the setup based on what you learned. Each domain below reflects one stage of that process, and each stage has its own set of skills, terminology, and Fusion-specific interface knowledge you need to master.
Domain 1: Simulation Prep
Simulation Prep
This domain covers everything that happens before a simulation study is even created - getting the CAD geometry, materials, and model condition ready for analysis.
- Preparing and simplifying geometry so it is suitable for meshing and solving
- Assigning and verifying appropriate materials and their physical properties
- Recognizing when a model needs defeaturing, cleanup, or idealization before a study begins
- Understanding how model quality upstream affects solve stability downstream
Candidates often underestimate this domain because it feels like "CAD work" rather than simulation work. But a large share of real-world failed static stress studies trace back to poor preparation: unassigned materials, unrealistic small features left in the geometry, or components not properly joined. Expect scenario-based questions that ask you to identify what needs to happen to a model before it is ready for setup.
Domain 2: Simulation Set Up
Simulation Set Up
Once the model is prepared, this domain tests your ability to configure the actual static stress study - constraints, loads, contacts, and mesh.
- Applying appropriate boundary conditions and constraints
- Defining loads that reflect the real-world scenario being simulated
- Configuring contact conditions between bodies in an assembly
- Setting mesh parameters and understanding refinement options
This is typically the densest domain in terms of interface knowledge. Expect active-screen and hot-area style questions that ask you to identify where a specific setting lives in the Fusion simulation workspace, as well as questions that present a scenario and ask which constraint or load type is correct. If you're unsure how heavily this domain is weighted relative to others, the complete breakdown of all five content areas is a good place to cross-check your understanding of the setup stage against the full objectives list.
Domain 3: Solve Simulation
Solve Simulation
This domain focuses on running the study itself: understanding solver behavior, resolving errors, and knowing what happens computationally once a study is submitted.
- Selecting appropriate solver settings for a static stress study
- Recognizing common solve errors and their likely causes
- Understanding convergence and how mesh quality affects solve outcomes
- Knowing when a study needs to be re-run after adjustments
Because Fusion is unavailable during the exam, questions in this domain rely heavily on graphic interpretation - you may be shown a solver log, error message, or partial results screen and asked to diagnose the issue. This is one of the areas where hands-on repetition inside Fusion pays off far more than reading alone, since recognizing solver behavior from memory is a pattern-matching skill built through practice.
Domain 4: Result Analysis
Result Analysis
Once a study solves, this domain tests whether you can correctly read and interpret the output - stress, displacement, and safety factor results.
- Interpreting stress and displacement plots correctly
- Evaluating safety factor results against design requirements
- Identifying whether results indicate a valid or invalid simulation
- Distinguishing real design issues from artifacts of poor setup
This domain often trips up candidates who are strong on the mechanics of Fusion but weaker on engineering judgment. A model can solve successfully and still produce misleading results if a load was misapplied or a mesh was too coarse in a critical region. Expect the exam to present a results screenshot and ask you to determine what the data is actually telling you, not just what the numbers say at face value.
Key Takeaway
Result Analysis questions frequently combine two domains at once - you may need to recall a Domain 2 setup choice to correctly explain a Domain 4 result, so study these two areas together rather than in isolation.
Domain 5: Study Refinement
Study Refinement
The final domain covers what happens after initial results are reviewed - adjusting the study to improve accuracy or address design concerns.
- Refining mesh in specific regions based on initial results
- Iterating on constraints or loads after reviewing outcomes
- Deciding when a study needs to be repeated versus adjusted
- Documenting or communicating changes made between iterations
Study Refinement closes the loop of the workflow tested across all five domains. It confirms that a candidate understands simulation as an iterative process rather than a one-shot task. Because this domain builds directly on the first four, it's often the section candidates feel least prepared for on a first attempt - reviewing the difficulty guide for the full exam can help set realistic expectations for how this domain interacts with the others under time pressure.
Question Formats You'll Actually See
The ACP-SIM-STRESS exam uses selected-response formats exclusively - there is no free-response or live software component. Formats include:
- Multiple choice: standard single-answer questions across all five domains
- Drag-and-drop: often used to sequence workflow steps or match settings to outcomes
- Active-screen: click on the correct location within a static Fusion interface image
- Hot-area: select a region of an image or diagram that matches the question
- Graphic interpretation: read a results plot, mesh view, or solver output and answer based on what's shown
The exam runs 45-60 questions within a 120-minute window, administered in English at Pearson VUE testing centers or via OnVUE online proctoring with identity verification tied to your Autodesk Account. Results are reported strictly as pass/fail, with no domain-by-domain score breakdown provided afterward - which is exactly why understanding the passing score requirements before you sit the exam matters more than it might for a scored exam.
| Domain | Workflow Stage | Core Skill Tested |
|---|---|---|
| Simulation Prep | Before study creation | Model and material readiness |
| Simulation Set Up | Study configuration | Constraints, loads, contacts, mesh |
| Solve Simulation | Running the study | Solver settings and error diagnosis |
| Result Analysis | After solve completes | Interpreting stress and safety factor data |
| Study Refinement | Iteration | Adjusting setup based on results |
Mapping a Study Plan to the Domains
Because the five domains follow the actual simulation workflow in order, it makes sense to study them in that same sequence rather than jumping around. A practical approach is to spend early study sessions on Simulation Prep and Simulation Set Up together, since weak fundamentals there compound into confusion in every later domain.
Simulation Prep + Set Up
- Practice geometry cleanup and material assignment in Fusion
- Review constraint, load, and contact terminology
Solve Simulation
- Run studies deliberately with mesh variations to observe solver behavior
- Collect examples of common error messages and their causes
Result Analysis + Study Refinement
- Practice reading stress and safety factor plots without live software
- Work through iteration scenarios: what changes, and why
Mixed Review
- Take timed practice questions across all five domains
- Revisit the objectives document to confirm no topic was skipped

If you want a condensed reference to keep nearby during final review, the one-page cheat sheet of must-know facts is built specifically around these five domains.
Who Hires ACP-SIM-STRESS Holders
Because the credential is built entirely around the Fusion simulation workflow, it tends to resonate most with employers who already use Fusion for mechanical design and want evidence that a candidate can independently run a static stress study from start to finish - not just operate the software casually. This includes design engineering teams, manufacturing firms validating part strength before production, and consultancies offering simulation services to clients who don't have in-house analysts.
If you're weighing whether the investment in exam fees and prep time is worthwhile for your career stage, the ROI analysis on whether the certification is worth it and the earnings analysis for certified professionals both dig into that question in more depth. For a broader look at eligibility and how Autodesk frames the experience expectations, the requirements and prerequisites guide covers the 400-1,200 hour preparation profile Autodesk describes and how it differs from a hard prerequisite.
Once you've internalized what each domain actually tests, practicing with realistic, domain-tagged questions is the best way to confirm readiness before exam day - our full practice test platform is built around these exact five content areas so you can identify weak domains before you sit the real thing. You can also run a shorter diagnostic set on the main practice site to see which domains need another pass before you book your slot.
Frequently Asked Questions
The official objectives document (091621) lists all five domains but does not publish individual weighting percentages, so candidates should prepare each domain thoroughly rather than assuming any one area is safe to skip.
No. Fusion software is unavailable during the exam, so all questions involving interface navigation, results interpretation, or solver diagnostics must be answered from memory using static images and scenario descriptions.
Autodesk does not publish a per-domain question count. The exam totals 45-60 questions across a 120-minute session, drawn from all five domains defined in the objectives file.
No. Autodesk describes roughly 400-1,200 hours of relevant Fusion experience as a preparation profile, not a mandatory training requirement, so self-study and hands-on practice can be sufficient depending on your background.
No, domains don't reset individually since the exam is pass/fail overall. After a first failed attempt you may be able to reschedule immediately depending on availability; after a second or later failed attempt, a 72-hour wait is required.
