- The exam has 40 questions in 3 hours: 10 hands-on (10-20 points each) and 30 multiple-choice (2 points each).
- Passing requires 70%, but because points vary by question, that is not a fixed 28-correct-answer threshold.
- You must hold CSWP, CSWA-S, and CSWP-S before attempting this Expert exam.
How to Read the 18 Published Areas
The SOLIDWORKS Simulation Expert (CSWE-S) exam page lists 18 areas where hands-on challenges may appear. Candidates searching for a "domain breakdown" often expect a table of percentages, as with many vendor-neutral certifications. This exam does not work that way. The list is a set of skill objectives. It is not a formal percentage-weighted partition, it does not claim to describe the multiple-choice component, and it does not tell you which topic is "most tested."
That distinction matters for how you study. Because no area carries an official weight, treating any single domain as a "high-value" topic is guesswork. A better approach is to build competence across all 18, with extra practice on areas that feed into many others. Meshing, contact, and results interpretation, for example, show up inside almost every other study type. If you want the broader picture of why this credential is considered demanding, see our analysis in How Hard Is the CSWE-S Exam? Complete Difficulty Guide 2026.
Exam Format and Point Structure
The exam runs 40 questions in a single 3-hour sitting. Ten are hands-on questions worth between 10 and 20 points each. Thirty are multiple-choice questions worth 2 points each. The minimum passing grade is 70%. The timer cannot be paused, and testing is delivered online through SOLIDWORKS and VirtualTester (older material refers to Tangix and TesterPRO, which is outdated terminology).
| Component | Count | Points per Question | Planning Implication |
|---|---|---|---|
| Hands-on questions | 10 | 10-20 | Each one can swing your score substantially; budget time by point value |
| Multiple-choice questions | 30 | 2 | Individually low value; do not let them consume hands-on time |
| Total time | 3 hours, one sitting, timer cannot be paused | ||
| Passing grade | 70% minimum | ||
Since question values differ, 70% does not translate into a uniform number of correct answers. A candidate who fully solves most hands-on questions can pass while missing several multiple-choice items, and the reverse is much harder. For a deeper explanation of how scoring thresholds behave, read CSWE-S Passing Score 2026: Exactly What You Need to Pass. Also note that the 10/30 question split says nothing about how topics are distributed. Do not infer domain weights from the format.
Prerequisites and Licensing Before You Study
Before the domains even matter, confirm you qualify. The mandatory prerequisites are passing all three of CSWP (Mechanical Design), CSWA-S (Simulation Associate), and CSWP-S (Simulation Professional). Full eligibility details are in CSWE-S Requirements 2026: Eligibility, Prerequisites & How to Qualify.
Software requirements are equally specific. You need SOLIDWORKS 2017 or later plus SOLIDWORKS Simulation Premium 2017 or later, and you must be able to unzip files. The 2017 figure is a software compatibility baseline, not an exam revision date. Be careful here: a CAD-only Premium license is not Simulation Premium. Many of the 18 areas, such as nonlinear dynamic and linear dynamic studies, require Simulation Premium capabilities, so a mismatched license can leave you unable to practice or complete the relevant questions.
Practical details: the fee is USD 149 in North America for one attempt, and retakes require at least 90 days plus a fresh exam credit. Full pricing context lives in CSWE-S Certification Cost 2026: Complete Pricing Breakdown.
Domains 1-3: Linear Stress, Contact, and Connectors
These three areas form the structural backbone. Nearly every later study type assumes you can set up fixtures, loads, and interactions correctly.
Domain 1: Linear stress
The foundation of the exam. You are expected to build, run, and interpret linear static studies quickly and correctly.
- Apply fixtures and external loads that reflect real constraints rather than over-constraining the model.
- Recognize singularities at sharp corners and point loads, and know why stress there may not converge.
- Choose between solid, shell, and beam idealizations when a model could be treated several ways.
Domain 2: Contact
Assemblies rarely behave like one fused body. Contact definitions decide whether load paths in your model are realistic.
- Distinguish bonded, no-penetration, and other contact conditions and when each is appropriate.
- Understand how global versus local contact settings interact and which one governs.
- Diagnose results that look wrong because of missing or incorrect contact rather than incorrect loading.
Domain 3: Connectors (bolts, pins, springs)
Connectors let you represent fasteners and compliant elements without modeling every thread or coil.
- Know when a bolt connector is the right abstraction versus modeling the fastener geometry.
- Set up pin and spring connectors with correct stiffness or preload inputs.
- Extract connector forces, which ties directly to Domain 18.
Domains 4-7: Shells, 2D Simplification, and Meshing
This cluster is about modeling judgment: choosing the right idealization and proving your mesh is trustworthy. These skills reduce solve time and are heavily rewarded in a timed hands-on environment.
Domain 4: Shells, including composite shells
Thin-walled parts are often better represented as shells than solids. Candidates should be comfortable with shell definitions from mid-surface geometry, thickness assignments, and the added complexity of composite shells, where layer stacking, thickness, and material orientation affect results. Be prepared to read layer-by-layer output rather than a single stress value.
Domain 5: 2D simplification
Symmetry and planar assumptions can turn a heavy 3D problem into a fast one. The skill is knowing which 2D approach fits the physical situation and recognizing when a simplification is invalid because the loading or geometry breaks the assumption. A correct 2D model that runs in seconds can free valuable minutes for harder questions.
Domain 6: Resolving meshing problems
Failed meshes are a fact of life with imported or complex geometry. Expect to diagnose why a mesh will not generate and apply fixes such as adjusting mesh controls, simplifying small features, or changing mesh type. This is a troubleshooting skill, and the speed of your diagnosis matters under a 3-hour clock.
Domain 7: Mesh convergence
Mesh convergence is the discipline of showing that your answer does not depend on element size. Know how to refine locally, compare results across successive meshes, and decide when a result has stabilized. Understand also why a stress singularity will never converge no matter how fine the mesh becomes, which links back to Domain 1.
Domains 8-13: Thermal, Frequencies, Drop Test, Buckling, and Linear Dynamics
This is the widest block of physics on the list, spanning heat transfer, vibration, impact, and stability.
Domain 8: Steady state and transient thermal
Know the difference between a steady-state solution and one that evolves over time.
- Define thermal loads and boundary conditions: heat power, convection, radiation, and fixed temperatures.
- Set time steps and total time sensibly for transient studies.
- Interpret temperature plots and know what they imply for the next domain.
Domain 9: Thermal stress
Thermal results often feed a structural study. Be ready to import temperatures from a thermal study into a static study and reason about constrained thermal expansion, where restricted growth produces stress even without any mechanical load.
Domain 10: Resonance frequencies and mode shapes
Frequency studies reveal natural behavior. Understand how constraints change mode shapes and frequencies, what mass participation tells you, and how to read mode shapes qualitatively. This domain is the gateway to the linear dynamic methods in Domain 13.
Domain 11: Drop test
Drop test studies model impact onto a rigid or compliant surface. Candidates should understand drop height or impact velocity inputs, orientation of the part at impact, and how to interpret the resulting stress and displacement over time. Setup choices can drastically change run time, so efficient modeling matters.
Domain 12: Linear buckling
Buckling asks whether a structure loses stability before it fails by stress. Know how to read the buckling load factor, why a factor below 1 means buckling under the applied load, and how multiple buckling modes should be interpreted. Remember this is the linear method; its limitations lead directly to nonlinear buckling in Domain 16.
Domain 13: Linear dynamic
This domain groups four distinct methods published by SOLIDWORKS, and each answers a different question.
- Modal time history: response to a load that varies with time.
- Harmonic: response to sinusoidal loading across a frequency range.
- Random vibration: statistical response to a power spectral density input.
- Response spectrum analysis: peak response to a base excitation such as shock or seismic input.
Be able to tell which method suits a described scenario, since choosing the wrong one is a common failure mode.
Domains 14-18: Nonlinear Studies, Configurations, and Results
The final group covers the most advanced solver behavior, plus two organizing skills that tie the whole exam together.
Domain 14: Nonlinear static
Nonlinear statics handle large displacements, nonlinear materials, and changing contact. Know how to set load steps and solver controls, and recognize convergence difficulties. Understand why a nonlinear solution may require incremental loading to find equilibrium.
Domain 15: Nonlinear dynamic
This combines time-dependent loading with nonlinear behavior. Expect to manage time step sizing, damping considerations, and the greater computational cost. Efficient setup, including sensible total time and output intervals, is part of the skill.
Domain 16: Nonlinear buckling
Where linear buckling gives an idealized critical load, nonlinear buckling follows the structure through large deflection, imperfections, and post-buckling behavior. Know when linear results are not conservative enough and how to read a load-displacement response to identify the onset of instability.
Domain 17: Assembly Configurations
Simulation studies can be tied to model configurations. Be comfortable running studies against different configurations of an assembly, suppressing components, and understanding how configuration changes propagate into study setup. This is a workflow skill that saves time when a question asks you to compare design variants.
Domain 18: Results (stress, displacement, reaction force, connector force)
Getting a solution is not the same as answering the question. Candidates must extract the specific quantity requested.
- Probe stress and displacement at defined locations.
- Retrieve reaction forces at fixtures and verify they balance applied loads.
- List connector forces for bolts, pins, and springs.
- Confirm units and result components before submitting a numeric answer.
Key Takeaway
Hands-on questions reward exact numeric answers. Practice reading the requested quantity precisely, such as a specific stress component or a reaction force in a named direction, since an otherwise correct model can still lose points on a misread result.
Sequencing the Domains Across Your Preparation
Because the 18 areas are unweighted, sequencing should follow dependencies rather than a ranking. Build the foundations first, then layer the physics that reuses them. The plan below is one logical ordering; adjust the pacing to your own baseline. For a broader plan, see the CSWE-S Study Guide 2026: How to Pass on Your First Attempt.
Foundations: Domains 1, 2, 3, 18
- Rebuild linear stress studies with realistic fixtures.
- Practice contact and connector setups on a small assembly.
- Drill result extraction so numeric answers become automatic.
Modeling judgment: Domains 4, 5, 6, 7
- Convert thin parts to shells, including a composite example.
- Apply 2D simplifications and check their validity.
- Break and repair meshes, then run a convergence comparison.
Thermal and vibration: Domains 8, 9, 10, 13
- Chain a thermal study into a thermal stress study.
- Run frequency studies, then each linear dynamic method.
Stability and nonlinear: Domains 11, 12, 14, 15, 16, 17
- Compare linear and nonlinear buckling on the same part.
- Practice nonlinear static and dynamic setups, then drop test and configuration workflows.
Finish with timed, mixed-domain sessions that mimic the exam's point-aware pacing: attack high-value hands-on questions first, and treat each 2-point multiple-choice item as a quick win rather than a time sink. Our CSWE-S Cheat Sheet 2026: One-Page Review of Must-Know Facts is a useful companion for final review.
Preparation Resources and What They Do Not Cover
SOLIDWORKS recommends the SOLIDWORKS Simulation course, Simulation Professional, the Simulation Learning Path, Dynamics, Nonlinear, and the built-in Simulation tutorials. The public course-contents PDFs for SOLIDWORKS Simulation and SOLIDWORKS Simulation Professional list chapter topics, but they are preparation curricula, not official exam-domain lists or weighted blueprints. Recommended training adds no mandatory course-hour prerequisite, and edition years in those documents do not indicate an exam revision date.
The most important gap: the issuer provides no official sample exam for this Expert credential. Third-party providers, including some listed in our research such as GoEngineer, CADfinity, TriMech, and community discussion on Reddit's r/SolidWorks, may offer training or timed mocks, but their contents are not official sample questions and should not be treated as such. CADfinity, for example, lists a timed mock exam lab, but its paid contents were not reviewed here. Evaluate any third-party material for yourself.
Given the lack of official samples, create your own exercises for each domain. If you want structured multiple-choice practice to complement your hands-on modeling, our CSWE-S practice test site offers question sets built around these topics. Questions about career payoff are covered in Is the CSWE-S Certification Worth It? Complete ROI Analysis 2026, and you can also review overall exam background at our main practice platform.
