What Is A CSWE-S?

The Short Answer: What a CSWE-S Is

A CSWE-S is the Certified SOLIDWORKS Expert - Simulation credential. SOLIDWORKS currently presents it on its certification pages as the "SOLIDWORKS Simulation Expert (CSWE-S)." It sits at the top of the simulation track in the SOLIDWORKS certification program and tests whether you can set up, run, troubleshoot, and interpret finite element analyses at a level well beyond the associate and professional exams.

The acronym "CSWE-S" is used by other credentials in unrelated fields. This article concerns only the SOLIDWORKS simulation credential. If you are looking for that exam, you are in the right place; if you arrived from a search about another certification with the same letters, none of the details below apply to it.

If you want the definitional angle from different directions, our short explainers cover the same ground: what CSWE-S stands for and what CSWE-S certification is. This article goes further, into structure, prerequisites, and what the exam actually asks of you.

Who Issues It and What It Proves

The issuer is SOLIDWORKS, the Dassault Systèmes brand that makes the software. That matters for two reasons. First, the exam is built around the software's own simulation tools and terminology, so fluency inside the interface counts for as much as theory. Second, the credential is a statement about practical capability: you have demonstrated, under time pressure, that you can carry real analyses from setup to defensible results.

Customer and student certificates carry no official expiration date, according to the SOLIDWORKS certification program Q&A. That makes the CSWE-S a durable line on a résumé, though software versions move on and employers will still expect current working knowledge.

The Three Credentials You Must Hold First

The CSWE-S is gated. Before you can sit it, you must have successfully passed all three of the following:

1. CSWP (Certified SOLIDWORKS Professional, Mechanical Design)
2. CSWA-S (Certified SOLIDWORKS Associate - Simulation)
3. CSWP-S (Certified SOLIDWORKS Professional - Simulation)

Notice the CAD-side requirement. Many simulation-focused engineers assume they can skip modeling credentials, but the Mechanical Design professional certification is mandatory here. If you are mapping your path, the full eligibility picture is covered in our CSWE-S requirements guide.

There is no mandatory course-hour prerequisite attached to the exam. Recommended training exists, but the gate is passing the three credentials above, not logging classroom time.

How the Exam Is Built: 40 Questions, 3 Hours

The exam is a single three-hour sitting with 40 questions, split into two kinds:

• 10 hands-on questions, each worth between 10 and 20 points
• 30 multiple-choice questions, each worth 2 points

The minimum passing grade is 70%. Because the hands-on questions carry different point values, 70% is not equivalent to a flat count of correct answers. You cannot translate it into "get 28 of 40 right." A candidate who nails most of the high-value hands-on problems and misses a handful of multiple-choice items can land very differently from one who does the reverse. For the scoring arithmetic and what it implies for strategy, see our CSWE-S passing score breakdown.

One caution: the split between question formats describes how the exam is delivered. It does not tell you how much of the exam covers any particular topic, and no official topic percentages have been published.

Software and Licensing: Simulation Premium Matters

To sit the exam you need SOLIDWORKS 2017 or later together with SOLIDWORKS Simulation Premium 2017 or later. You also need the ability to unzip files, since exam materials are delivered as archives that you extract and open locally.

This is the most common preparation trap. "SOLIDWORKS Premium" is a CAD package tier; "Simulation Premium" is a separate simulation product tier. A CAD-only Premium license will let you build the geometry but will not give you the nonlinear and dynamic study types the exam expects. Confirm your license before booking, not after.

Testing is delivered online through SOLIDWORKS and the VirtualTester platform. Current program instructions point to the VirtualTester Web Client, while older material refers to Tangix and TesterPRO. If you find tutorials using those older names, they describe the same testing lineage, so check the current program page for the live procedure.

The 18 Published Skill Areas

SOLIDWORKS publishes a list of areas where hands-on challenges may appear. There are 18, and they are best read as an unweighted skill list rather than a formal blueprint. They are not course chapters, they do not describe the multiple-choice section exhaustively, and no official ranking of importance exists. For a deeper walk-through, see our complete guide to all 18 content areas.

The published areas are:

1. Linear stress
2. Contact
3. Connectors (bolts, pins, springs)
4. Shells, including composite shells
5. 2D simplification
6. Resolving meshing problems
7. Mesh convergence
8. Steady state and transient thermal
9. Thermal stress
10. Resonance frequencies and mode shapes
11. Drop test
12. Linear buckling
13. Linear dynamic (modal time history, harmonic, random vibration, response spectrum analysis)
14. Nonlinear static
15. Nonlinear dynamic
16. Nonlinear buckling
17. Assembly configurations
18. Results (stress, displacement, reaction force, connector force)

It helps to cluster them mentally into families, because skills within a family reinforce each other:

What the Hands-On Challenges Demand

The ten hands-on questions are the heart of the exam. You open provided files, build or modify a study, run it, and report a specific result. Two habits separate comfortable candidates from stressed ones.

Read the question for the number it wants

Each challenge ends in a reported value: a maximum stress, a displacement at a location, a reaction force, a connector force, a natural frequency. The final area on the published list, Results, is effectively the skill of extracting the correct number from the correct entity in the correct units. A perfectly solved study with the wrong probe location earns nothing.

Treat meshing and convergence as exam skills, not chores

Two of the 18 areas are about meshing. In practice, you will meet problems where a default mesh fails, where a refined mesh changes the answer, or where you must justify that a result is mesh-independent. Practicing a refinement loop on a filleted part, and watching how a sharp re-entrant corner behaves differently from a smooth one, builds the judgment these questions probe.

For a realistic sense of how demanding this is, our article on how hard the CSWE-S exam is discusses the difficulty drivers without inventing statistics. And if you are wondering about success rates, our pass rate article explains why no verified official figure exists.

Fees, Registration, and Retakes

The exam fee is USD 149 in North America, which covers one attempt, per the SOLIDWORKS Certification Program page. Pricing in other regions may differ, so confirm through the program page or your reseller. If you pass, no additional certificate fee is implied beyond that exam credit.

If you do not pass, a retake requires waiting at least 90 days and purchasing a fresh exam credit. That waiting period makes a first-attempt pass especially valuable, and it is the main reason to prepare thoroughly rather than treating the first sitting as a trial run. For the broader cost picture, including software and training, see our CSWE-S certification cost breakdown.

Preparing Without an Official Sample Exam

SOLIDWORKS states plainly that it provides no official sample exam for the Expert credential. That is unusual compared with lower tiers and changes how you should prepare. You cannot rehearse against released questions, so your practice has to come from the skills list and from the training material the issuer recommends.

The recommended preparation includes the SOLIDWORKS Simulation course, SOLIDWORKS Simulation Professional, the Simulation Learning Path, Dynamics, Nonlinear, and the built-in Simulation tutorials. The public course contents pages for the main Simulation and Simulation Professional courses are useful for scanning topics, but they are curriculum outlines rather than exam blueprints. Treat them as a source of practice scenarios, not as a map of what will be asked.

Third-party providers such as GoEngineer, CADfinity, TriMech, and Abundent Academy offer training and, in some cases, timed mock exams. CADfinity, for instance, lists a timed mock exam lab. These are commercial resources and should not be confused with official sample questions. The r/SolidWorks community on Reddit can help with specific modeling questions, though it is not an authoritative source of exam facts.

A domain-ordered plan

Since generic study advice is everywhere, here is one CSWE-S-specific sequencing idea: order your practice so that earlier skills feed later ones.

Nonlinear topics come late because they lean on contact and mesh judgment from earlier blocks. For a fuller plan and resource list, see our CSWE-S study guide, and keep our one-page CSWE-S cheat sheet handy for last-minute review.

Who Should Pursue It, and Where It Fits

The credential suits engineers whose daily work involves SOLIDWORKS Simulation: structural analysts, product development engineers who validate their own designs, and consultants or application engineers who support others. Because you must already hold CSWP, CSWA-S, and CSWP-S, you are likely already a practicing user, and the Expert exam signals that you have moved from competent to advanced.

Employers who value it tend to be product design firms, manufacturers with in-house analysis, engineering consultancies, and SOLIDWORKS resellers and training providers, where credibility with customers matters. For role types and what to look for, see our overview of CSWE-S jobs.

On earnings and return on investment, be cautious. No certification-specific salary uplift has been verified, and no official pass-rate figure exists, so any article claiming precise numbers is guessing. For a measured discussion, read whether the CSWE-S is worth it and our salary guide, which stay qualitative where data is thin.
