When Does Your Team Need SOLIDWORKS Simulation?
If you run an engineering team, you have probably heard the pitch for SOLIDWORKS Simulation. Maybe you have even looked at the price tag and wondered whether it is worth it. The honest answer is: for most teams producing physical products, yes. But the timing matters, and so does knowing when it is not the right move.
This post breaks down exactly that. Who needs Simulation, what problems it solves, when to hold off, and what it actually looks like to get started.
Why do teams add Simulation?
When engineering managers come to us asking about Simulation, it almost always comes down to one of three business pressures: safety, performance, or cost.
Safety
If your product is going to be under structural load in the real world and a failure has consequences, Simulation is not optional, it is due diligence. Think about access equipment used in industrial maintenance. A rolling ladder that locks into place next to an aircraft. A technician is not going to stand perfectly centered on it. They are going to lean over the side, reach in odd directions, put dynamic load on a cantilever that was only designed for a static load at the center. Every one of those scenarios needs to be validated, and physical testing for each configuration is not realistic. Simulation is how you validate those use cases, document the results, and put a certification label on the product.
The same logic applies to any cantilevered structure, pressure vessel, or assembly where structural failure has safety consequences. If a board on scaffolding needs to hold a person at height, you need to know it will hold. That is the simplest possible entry point for Simulation.
Performance
Performance problems are less visible than safety failures, but they are just as expensive. A common example is thermal management. If you have an electronics enclosure with components generating heat and fans to cool them, you need to know whether that cooling is actually working before you commit to tooling. SOLIDWORKS Flow Simulation lets you model airflow through the enclosure, identify hot spots, and optimize fan placement or enclosure geometry before a single part is manufactured.
The same principle applies to fluid handling, sealing performance, and any product where behavior under operating conditions is not obvious from geometry alone.
Cost
This is the angle engineering managers most often overlook. Simulation is not just about preventing failure, it is about not over-engineering. If you are designing a bracket at 10-gauge steel when 14-gauge would hold, you are adding weight, material cost, and shipping cost to every unit you produce. Simulation tells you exactly where the margin is so you can make the design more efficient without guessing.
For any product being produced at scale, even a modest material reduction per unit compounds quickly.
When doesn’t SOLIDWORKS Simulation make sense?
There are two situations where adding Simulation to the workflow too early creates more friction than value.
The first is the early ideation phase. If you are still iterating on form, rapidly 3D printing concepts, and the design is going to change fundamentally before anything gets locked down, running structural analysis is premature. Get the geometry to a point where the general shape and constraints are settled, then bring Simulation in.
The second is true one-off production where the cost of adding material is negligible. If you have a single custom weldment and bumping the wall thickness by one gauge eliminates all structural uncertainty at a cost difference of a few dollars, that may be faster and simpler than setting up and running an analysis. Simulation earns its keep when it is applied at scale or when the analysis complexity warrants the investment.
A good rule of thumb: if the cost of being wrong is meaningful and the product will be produced in quantity, Simulation belongs in the process.
What experience is needed for SOLIDWORKS Simulation?
There is a category of benefit that does not show up on a spec sheet but matters a lot to engineering managers who are scaling teams: Simulation bridges the knowledge gap between experienced engineers and newer ones.
A veteran fabricator can look at a bracket design and tell you by instinct whether it will fail. A newer engineer cannot. Simulation gives newer engineers a reliable way to validate their assumptions, get feedback early, and build good design intuition over time. As you add engineers to a growing team, Simulation functions as a quality check that does not depend on the judgment of your most experienced person being in the room.
What Getting Started Actually Looks Like
Most engineers are more intimidated by Simulation than they need to be. The basic workflow for a structural analysis is four steps.
• Define your fixed conditions. Which surfaces are constrained? Think of it like putting a part in a vice. Select those faces in SolidWorks and define them as fixed.
• Apply your loads. What force, pressure, or moment is being applied, and in what direction? Select the surface and enter the value in your preferred units.
• Create the mesh. This is where some people hesitate, but modern computing power and SolidWorks defaults have made this much less painful than it used to be. In most cases, the default mesh settings work well for initial analysis.
• Run and review results. SolidWorks presents stress, displacement, and strain results that you can rotate, zoom, and interrogate from any angle. One useful feature: you can scale up the deformation visualization to clearly see how and where the part moves, even if real-world displacement is small.
The interface lives inside SolidWorks, so if your team is already familiar with the design environment, the learning curve is shorter than you might expect.
How do you choose the right SOLIDWORKS Simulation Package?
When evaluating SOLIDWORKS Simulation package, two questions determine which package fits your needs.
Linear vs. nonlinear: Linear analysis covers most structural scenarios up to the yield point of the material. If you need to understand behavior past yield or involve complex contact conditions like O-ring compression and sealing performance, nonlinear is required.
Static vs. dynamic: Static analysis models a settled, steady-state load. Dynamic analysis models impact, vibration, or time-varying forces. An electronics enclosure mounted to a vehicle that will experience shock loads is a dynamic problem. A bracket holding a fixed weight is static.
There is also the question of where you want the solver to run. Some packages solve locally on the workstation. Others connect to cloud computing resources for more intensive jobs, which can free up your engineering workstations and reduce solve time on large assemblies.
Not sure which package applies to your application? That is exactly the kind of question our team works through with customers before any purchase decision. Reach out and we will help you map your specific scenarios to the right toolset.
Is SOLIDWORKS Simulation Necessary?
SOLIDWORKS Simulation is not a luxury for large engineering departments. It is a practical tool for any team producing physical products where safety, performance, or unit economics matter. The question is not really whether you need it, but when to apply it and to which products.
If you are producing parts at scale, adding simulation to a product line that carries structural requirements, or building a team that does not yet have deep domain experience to rely on, Simulation is worth a serious look.
