CSWE-S Certification

TL;DR
  • The exam has 40 questions in 3 hours: 10 hands-on (10-20 points each) and 30 multiple-choice (2 points each).
  • You must already hold CSWP, CSWA-S, and CSWP-S before you can sit this Expert exam.
  • SOLIDWORKS Simulation Premium 2017 or later is required; a CAD-only Premium license will not run the studies.
  • The issuer publishes no official sample exam, so build your own practice models around the 18 listed areas.

What the SOLIDWORKS Simulation Expert Credential Actually Is

The Certified SOLIDWORKS Expert - Simulation credential, listed by the issuer as "SOLIDWORKS Simulation Expert (CSWE-S)", sits at the top of the Simulation certification track offered by SOLIDWORKS (Dassault Systèmes). It is not an entry-level test of whether you can click through a static study. It is a timed, hands-on assessment of whether you can set up, troubleshoot, interpret, and defend finite element analysis (FEA) results across a wide range of study types.

If you are new to the acronym or want the basics first, our explainer on what CSWE-S certification is covers the naming and the track. This article goes deeper into the mechanics: what the exam contains, what you need installed, how the points work, and how to prepare when the issuer provides no sample exam.

Identity check: "CSWE-S" in this article means the SOLIDWORKS Simulation Expert credential only. The acronym is shared with unrelated credentials in other fields, so make sure any prep material, fee quote, or pass-rate claim you read is actually about the SOLIDWORKS exam.

Prerequisites and Simulation Premium Licensing

The three mandatory prerequisites

You cannot register for this exam on skill alone. The issuer requires that you have successfully passed all three of the following:

  • CSWP (Mechanical Design) - the professional-level modeling credential
  • CSWA-S (Simulation Associate) - the entry credential in the Simulation track
  • CSWP-S (Simulation Professional) - the intermediate Simulation credential

That chain matters for planning. If you hold CSWP but not the two Simulation credentials, your timeline starts well before the Expert exam. Our CSWE-S requirements guide walks through eligibility and how to qualify step by step.

Software you need on your machine

The exam requires SOLIDWORKS 2017 or later plus SOLIDWORKS Simulation Premium 2017 or later, and you must be able to unzip files, since exam models are delivered as downloads. Note that 2017 is a software compatibility baseline, not an exam revision date.

Licensing trap: A SOLIDWORKS Premium license (the CAD package) is not the same as Simulation Premium. Several of the exam's areas, including nonlinear static, nonlinear dynamic, and nonlinear buckling, depend on Simulation Premium capability. Confirm that your installation actually exposes those study types before you pay for an attempt.

Exam Format, Scoring, and Point-Aware Pacing

The exam is one sitting of 3 hours with 40 questions. The mix is what makes pacing interesting:

ComponentCountPoints per questionNature
Hands-on questions1010-20 points eachBuild or modify a study, then report a result
Multiple-choice questions302 points eachConceptual and interpretive

The minimum passing grade is 70%. Because the questions carry different point values, 70% is not a flat "28 of 40 correct" rule. A candidate could miss several multiple-choice questions and still pass if the hands-on questions are strong, or the reverse. Read the details in our CSWE-S passing score breakdown.

Planning time around points

The hands-on questions carry most of the available points, so they deserve most of your clock. A reasonable approach, without pretending to know any hidden grading rubric:

  1. Skim all 40 questions first and note which hands-on items look like areas you have practiced repeatedly.
  2. Bank the quick wins: multiple-choice items are only 2 points each, but they are fast if you know the concept.
  3. Give each hands-on question a time budget proportional to its point value, and move on when you hit it. The timer cannot be paused.
  4. Return to partially solved hands-on questions with whatever time remains.

Key Takeaway

The question-format split (10 hands-on, 30 multiple-choice) describes how you answer, not how topics are weighted. Do not infer that any single domain is "worth" a certain percentage; the issuer publishes no weighted domain breakdown.

The 18 Published Areas for Hands-On Challenges

The issuer's page lists the areas where hands-on challenges may appear. These are unweighted skill objectives, not course chapters, and they are not an exhaustive outline of the multiple-choice portion. For a longer walkthrough of each, see our complete guide to all 18 CSWE-S content areas. Here is how they cluster in practice.

Structural fundamentals: Linear stress, Contact, Connectors, Shells, 2D simplification

These are the bread and butter of everyday Simulation work, and the exam expects you to choose the right idealization, not just run a study.

  • Linear stress: know when linear assumptions hold and when they quietly fail.
  • Contact: decide between bonded, no-penetration, and other contact conditions, and recognize how a contact choice changes load paths.
  • Connectors (bolts, pins, springs): understand how each connector transfers load and what connector force results mean.
  • Shells, including Composite shells: mid-surface idealization, thickness assignment, and layered definitions.
  • 2D simplification: recognize when plane stress, plane strain, or axisymmetry can replace a 3D model.

Mesh quality: Resolving meshing problems and Mesh convergence

Covered in detail in the next section. These two areas underpin trust in every other result.

Thermal: Steady state and transient thermal, and Thermal stress

Thermal studies feed structural ones. Expect to define heat sources, convection, and radiation conditions, then carry temperatures into a stress analysis.

Dynamics and stability: Resonance frequencies and mode shapes, Drop test, Linear buckling, Linear dynamic

Linear dynamic spans modal time history, harmonic, random vibration, and response spectrum analysis. Each answers a different physical question, and part of the skill is matching the loading description to the correct study type.

Nonlinear: Nonlinear static, Nonlinear dynamic, Nonlinear buckling

These require Simulation Premium. Material nonlinearity, large displacement, and contact-driven nonlinearity all change how you set up solver controls and interpret convergence.

Workflow and reporting: Assembly Configurations and Results

Assembly Configurations test whether you can manage multiple model states efficiently. Results (stress, displacement, reaction force, connector force) tests whether you can extract and sanity-check the numbers you were asked for.

Meshing Problems and Mesh Convergence

Two of the 18 areas are explicitly about the mesh, and they punish candidates who treat meshing as an afterthought.

Resolving meshing problems

A failed mesh is a common reason a hands-on question stalls. Practice the usual diagnostic loop: identify the offending faces or bodies from the failure message, decide whether the cause is geometry (sliver faces, tiny gaps, interferences) or mesh settings, and fix the root cause instead of simply shrinking the element size. Knowing the difference between standard, curvature-based, and blended-curvature mesh options, and when mesh controls help, is core material.

Mesh convergence

Mesh convergence is about demonstrating that your answer stops changing meaningfully as the mesh is refined. Be ready to:

  • Refine globally or locally at stress concentrations and compare the same result quantity across runs.
  • Explain why a singularity (a sharp re-entrant corner or point load) never converges, and why you should not chase that peak.
  • Choose a result quantity that is meaningful to track, rather than whichever number looks most dramatic.
Practice habit: Take one model of your own and run it at three mesh densities, logging a displacement and a stress value each time. The goal is to feel the difference between a converging quantity and a singularity-driven one before the clock is running.

Thermal Stress, Linear Dynamics, and Nonlinear Buckling

These three topics are good examples of how the exam links concepts together instead of testing them in isolation.

Thermal stress

Thermal stress usually means a two-step workflow: solve a steady-state or transient thermal study, then use the resulting temperature distribution as a load in a structural study. Common errors include forgetting to link the studies, using inconsistent reference temperatures, or restraining a part so rigidly that thermal expansion produces unrealistic stress. Understand both free expansion and constrained expansion.

Linear dynamics

Linear dynamic questions are about selecting the correct tool for the loading description:

Study typeTypical loading description
Modal time historyA defined load that varies over time
HarmonicSinusoidal excitation across a frequency range
Random vibrationStatistical excitation described by a spectrum
Response spectrumBase excitation characterized by a response spectrum

All of them build on a frequency (modal) solution, so a solid grasp of resonance frequencies and mode shapes pays off twice: it is its own listed area and the foundation for the linear dynamic family.

Nonlinear buckling

Linear buckling gives you a load factor for an idealized structure, but real structures with imperfections, large deflections, or material yielding behave differently. Nonlinear buckling tracks the load-displacement response incrementally, so be ready to discuss load stepping, solver convergence behavior, and how to read a result that shows loss of stiffness. Comparing the linear buckling load factor with the nonlinear result is a classic way to understand how conservative or unconservative the linear estimate is.

Key Takeaway

When a question names a physical situation instead of a study type, your first job is classification: static or dynamic, linear or nonlinear, thermal involved or not. Choosing the wrong study type costs more points than any setup slip afterward.

Registration, Fee, Retakes, and Validity

  • Fee: USD 149 in North America, covering one attempt, per the SOLIDWORKS Certification Program page. The full picture, including regional differences and attempt credits, is in our CSWE-S certification cost breakdown.
  • Delivery: online through SOLIDWORKS/VirtualTester. Current program instructions link the VirtualTester Web Client, while older material refers to Tangix and TesterPRO. If you see those older names in forum posts, they describe the same testing lineage, not a different exam.
  • Timer: the 3-hour clock cannot be paused, so arrange a quiet, interruption-free window and test your connection and software beforehand.
  • Retakes: at least 90 days between attempts, and each retake needs a fresh exam credit.
  • Validity: per the program Q&A, customer and student certificates have no official expiration date.

For scheduling questions, see our page on CSWE-S exam dates and scheduling.

Preparing When No Official Sample Exam Exists

The issuer explicitly states that it provides no official sample exam for this Expert credential. That changes how you should prepare. Instead of memorizing a past paper, you build a practice library that mirrors the 18 listed areas.

Use the recommended curriculum as a skills map

SOLIDWORKS recommends preparation through SOLIDWORKS Simulation, Simulation Professional, the Simulation Learning Path, Dynamics, Nonlinear, and the built-in Simulation tutorials. The public course-contents PDFs for the Simulation and Simulation Professional courses are useful for seeing which topics the training covers. Keep in mind they are curriculum contents, not exam blueprints, and recommended training adds no mandatory course-hour prerequisite.

Build your own timed drills

For each of the 18 areas, create or find one small model and practice a complete pass: set up, solve, extract a specific number, and sanity-check it. Pair the hands-on drills with conceptual questions in the multiple-choice style, such as "which contact condition fits this assembly," "what does this convergence plot imply," or "which dynamic study matches this loading."

Third-party providers advertise timed mock exams. For example, CADfinity lists a "CSWE-S Exam Lab" with timed mocks and a debrief. Treat any such product as supplementary practice, not as official sample questions. For structured multiple-choice practice, our CSWE-S practice test site is built for exactly that kind of drilling.

For a full roadmap, read the CSWE-S study guide, and if you want a quick review sheet near exam day, the CSWE-S cheat sheet condenses the key facts.

Sequencing Your Weeks by Domain

Generic scheduling advice is easy to find; the useful question is which topics to place first. Because later areas reuse earlier ones, this order follows the dependency chain:

Week 1

Foundations and mesh trust

  • Linear stress, Contact, Connectors
  • Resolving meshing problems and Mesh convergence, since every later study depends on a trustworthy mesh
Week 2

Idealization and thermal

  • Shells (including Composite shells) and 2D simplification
  • Steady state and transient thermal, then Thermal stress
Week 3

Frequency-based topics

  • Resonance frequencies and mode shapes first, then Linear buckling
  • Linear dynamic study types, which build on the modal solution
  • Drop test
Week 4

Nonlinear and workflow

  • Nonlinear static, Nonlinear dynamic, Nonlinear buckling
  • Assembly Configurations and Results extraction, then full timed runs

Adjust the length to your background. A candidate who works in nonlinear analysis daily may compress week 4, while someone coming straight from the CSWP-S exam may need longer on thermal and dynamics. For a sense of where candidates typically struggle, see how hard the CSWE-S exam is. No verified pass-rate figure exists from the issuer, which our pass rate discussion explains in more detail.

Career Context: Who Values This Credential

Simulation engineers, analysts, and design engineers who own FEA validation inside product development teams are the natural audience. Reseller and training organizations in the SOLIDWORKS ecosystem, such as GoEngineer, TriMech, and CADfinity, publish exam-related and training content, and consulting or in-house analysis groups often look for demonstrated hands-on Simulation depth. For openings and role types, see our overview of CSWE-S jobs.

On the money side, no certification-specific salary uplift has been verified, so treat any specific number you see online with caution. Our ROI analysis and salary guide discuss how to evaluate the credential qualitatively, based on the roles you are targeting and the credibility it adds to your analysis work.

Realistic expectation: The credential is best understood as proof of structured, verified skill across a broad range of study types. It strengthens a profile; it does not replace project experience or a portfolio of validated analyses.

Frequently Asked Questions

Do I need to pass CSWP, CSWA-S, and CSWP-S before taking this exam?

Yes. The issuer lists all three as mandatory prerequisites: CSWP (Mechanical Design), CSWA-S (Simulation Associate), and CSWP-S (Simulation Professional). Details are in our requirements guide.
