- CSWE-S is the SOLIDWORKS Simulation Expert credential issued by SOLIDWORKS (Dassault Systèmes).
- You must first pass CSWP, CSWA-S, and CSWP-S before you can sit for it.
- The exam has 40 questions in 3 hours: 10 hands-on and 30 multiple choice.
- The minimum passing grade is 70%, but question point values differ.
What CSWE-S Actually Is
CSWE-S stands for Certified SOLIDWORKS Expert - Simulation. SOLIDWORKS, a Dassault Systèmes brand, issues it, and the current issuer page titles it "SOLIDWORKS Simulation Expert (CSWE-S)". It sits at the top of the simulation certification track, above the Associate and Professional levels, and it is aimed at engineers who run finite element analysis (FEA) studies as a regular part of their work rather than occasionally.
The name matters because several unrelated credentials share similar acronyms. This one is strictly a SOLIDWORKS software-proficiency certification. It does not cover social work, systems engineering, or any other field. If you want a quick orientation on the terminology, see What Does CSWE-S Stand For? and CSWE-S Meaning.
Unlike entry-level certifications, the Expert exam does not test whether you can find a command. It tests whether you can build a defensible analysis: choose the right study type, set up contacts and connectors correctly, mesh a difficult model, check convergence, and interpret results. The hands-on component rewards genuine modeling judgment under a running clock.
The Three-Credential Gate
CSWE-S is not an entry point. The issuer requires you to have successfully passed all three of the following before attempting it:
- CSWP (Mechanical Design): the Certified SOLIDWORKS Professional credential for part, assembly, and drawing skills.
- CSWA-S (Simulation Associate): foundational simulation knowledge.
- CSWP-S (Simulation Professional): intermediate simulation capability.
This ladder means that by the time you reach the Expert exam, you are expected to be comfortable with basic static studies and the SOLIDWORKS modeling environment. The Expert exam builds on that base and moves into contact, thermal, dynamic, and nonlinear territory.

Exam Format: Hands-On Plus Multiple Choice
The exam is one 3-hour sitting with 40 questions, split into two kinds:
| Component | Number of Questions | Points Each |
|---|---|---|
| Hands-on questions | 10 | 10 to 20 points |
| Multiple-choice questions | 30 | 2 points each |
The minimum passing grade is 70%. Because the hands-on questions carry 10 to 20 points and the multiple-choice questions carry only 2 points, the 70% threshold is not equivalent to answering a fixed number of questions correctly. A single hands-on question can be worth as much as several multiple-choice items combined, so the weighting of your time deserves thought. Our CSWE-S Passing Score 2026 article explores the scoring mechanics in more detail.
The 3-hour timer cannot be paused. That has real consequences: a hands-on model that fights you with a meshing failure can silently consume time you intended for the multiple-choice block. The format split also tells you nothing about topic weighting, since the issuer does not publish percentage weights for the skill areas.
The 18 Skill Areas Explained
The issuer's page lists 18 areas where hands-on challenges may appear. These are unweighted skill objectives, not a formal percentage-based blueprint and not an exhaustive outline of the multiple-choice questions. No single area can be called "most heavily tested" based on published information. For the full list in context, see CSWE-S Exam Domains 2026: Complete Guide to All 18 Content Areas. Here is how the areas cluster in practice.
Structural Foundations
Linear Stress, Contact, and Connectors
These three areas form the backbone of most assembly analyses.
- Linear stress: setting fixtures, loads, and material behavior correctly, and recognizing when linear assumptions break down.
- Contact: choosing between bonded, no-penetration, and other contact conditions and understanding how they change load paths.
- Connectors (bolts, pins, springs): idealizing fasteners and supports, and reading the forces they carry.
Idealization and Mesh Quality
Shells, 2D Simplification, Meshing Problems, and Mesh Convergence
Expert-level work often depends on choosing the right model representation before solving anything.
- Shells, including composite shells: knowing when a thin body should be a shell and how layered composite properties are defined.
- 2D simplification: reducing a 3D problem to a plane or axisymmetric model where valid.
- Resolving meshing problems: diagnosing why a mesh fails and fixing geometry or settings.
- Mesh convergence: refining the mesh until results stop changing meaningfully, rather than trusting a single run.
Thermal and Coupled Physics
Thermal and Thermal Stress
Heat transfer appears in two linked areas.
- Steady state and transient thermal: applying heat sources, convection, and time-dependent conditions.
- Thermal stress: feeding a temperature field into a structural study and interpreting the resulting stresses.
Dynamic and Stability Studies
Frequencies, Drop Test, Buckling, and Linear Dynamics
These areas move beyond static loading.
- Resonance frequencies and mode shapes: extracting natural frequencies and reading what each mode represents.
- Drop test: setting up impact scenarios.
- Linear buckling: estimating buckling load factors for slender or thin structures.
- Linear dynamic: modal time history, harmonic, random vibration, and response spectrum analysis.
Nonlinear Studies
Nonlinear Static, Nonlinear Dynamic, and Nonlinear Buckling
Nonlinear analysis is where many candidates feel the Expert exam's difficulty.
- Nonlinear static: large deformation, material nonlinearity, and incremental loading.
- Nonlinear dynamic: time-dependent response with nonlinear behavior.
- Nonlinear buckling: post-buckling behavior that a linear buckling study cannot capture.
Workflow and Reporting
Assembly Configurations and Results
- Assembly Configurations: managing studies across different configurations of the same model.
- Results (stress, displacement, reaction force, connector force): extracting and interpreting the quantities an engineer actually reports.
Results interpretation touches every other area. A correctly built study that you read incorrectly still produces a wrong answer, so this is worth practicing alongside each analysis type rather than as a standalone topic.
Software and Licensing Requirements
You need SOLIDWORKS 2017 or later together with SOLIDWORKS Simulation Premium 2017 or later, and you must be able to unzip files, since exam materials are delivered as archives. The 2017 figure is a software compatibility baseline, not an indicator of when the exam outline was last revised.
Fees, Retakes, and Test Delivery
The listed fee is USD 149 for North America, covering one attempt. Pricing in other regions may differ, so check the SOLIDWORKS Certification Program page for your location. For a complete cost picture including preparation, see CSWE-S Certification Cost 2026: Complete Pricing Breakdown.
- Delivery: online through SOLIDWORKS and VirtualTester. Current program instructions link the VirtualTester Web Client, while older material uses Tangix or TesterPRO terminology. If you see those older names, they refer to earlier delivery tooling.
- Retakes: require at least 90 days between attempts and a fresh exam credit.
- Timer: cannot be paused once started.
- Validity: customer and student certificates have no official expiration date.

Who Benefits From This Credential
The credential suits analysts, design engineers, and simulation specialists whose employers use SOLIDWORKS Simulation for product validation. Typical settings include product development groups, engineering consultancies, and reseller or training organizations that support SOLIDWORKS customers. A CSWE-S shows that you can handle the full range of simulation types, not just basic static studies, which can distinguish you when roles involve thermal, vibration, or nonlinear problems.
There is no verified official pass-rate figure or certification-specific salary uplift, so any claim of a precise earnings bump should be treated skeptically. Think of the credential as documented evidence of skill that supports a case for responsibility or advancement, rather than a guaranteed pay change. For more on the career angle, see Is the CSWE-S Certification Worth It? and CSWE-S Jobs.
Sequencing Your Preparation
Because the exam mixes hands-on modeling with multiple-choice recall, order your preparation by dependency: master the foundations that every later topic relies on, then add the specialized physics. The issuer's recommended preparation includes the SOLIDWORKS Simulation and Simulation Professional courses, the Simulation Learning Path, Dynamics, Nonlinear, and the built-in Simulation tutorials. These recommendations add no mandatory course-hour prerequisite.
Linear stress, contact, connectors
- Rebuild assemblies with different contact and connector choices and compare reaction forces.
- Practice reading results immediately after each run.
Idealization and mesh quality
- Convert models to shells and 2D, then run mesh convergence checks.
- Deliberately break meshes and practice resolving them.
Thermal and dynamic studies
- Run steady state and transient thermal, then carry results into thermal stress.
- Extract frequencies and work through harmonic and random vibration setups.
Nonlinear and timed rehearsal
- Work through nonlinear static, dynamic, and buckling examples.
- Run full 3-hour sessions, spending hands-on time in proportion to the points each question carries.
This schedule is a suggestion, not an official plan; adjust it to your strengths. Nonlinear topics are placed last because they assume fluency with contact, meshing, and linear behavior. For a broader walkthrough, see CSWE-S Study Guide 2026: How to Pass on Your First Attempt, and for a quick fact review, the CSWE-S Cheat Sheet. If you are weighing effort against reward, How Hard Is the CSWE-S Exam? gives perspective, and our practice questions help you rehearse the multiple-choice portion.
Key Takeaway
Treat the hands-on questions as the higher-stakes part of the exam: each is worth 10 to 20 points versus 2 for a multiple-choice item. Practice finishing a full analysis, including result interpretation, inside a fixed time budget rather than only learning individual commands.
