Let’s be honest, searching for a cfd company is easy. The internet is flooded with them. But you’re not looking for someone to just press “run” on a solver. You have a complex problem—a heat exchanger underperforming, an airfoil stalling unexpectedly, a mixing tank with dead zones—and the cost of getting it wrong is high. It’s not just about getting a colorful contour plot; it’s about getting an answer you can bet your budget, your timeline, and your reputation on.
A few months back, a project manager we’ll call Mr. Rostropovich came to us. His team was designing a new series of hydrokinetic turbines. They had two failed prototypes sitting on his desk, physical monuments to a simulation that looked good on screen but didn’t translate to the real world. The pressure from management was immense; the next physical test was budgeted at over a quarter of a million Euros, and they couldn’t afford another failure.
His problem wasn’t a lack of data; it was a lack of confidence in the data. The previous firm had delivered results, but they couldn’t adequately explain why the flow separation was happening so much earlier than predicted. It was a classic “black box” scenario. We spent the first week not running simulations, but deconstructing their previous methodology, pinpointing the flawed turbulence model assumption that was the root cause. That was one of the projects over the last 7 years that really cemented our process. It’s rarely the geometry that’s wrong; it’s the underlying physics that have been misunderstood.
We know the feeling. Staring at a residuals plot that refuses to converge, wondering if your mesh is too coarse, too fine, or if the boundary conditions are just plain wrong. Those are the technical weeds. But the real goal is to get out of those weeds and walk into a design review meeting with a clear, defensible recommendation that saves the company money or gets your thesis approved. We handle the brutal technical details so you can focus on the strategic outcome.
Anyone can generate an image of fluid flow. Our job is to ensure that image represents physical reality. We deliver reports and data that are not just illustrative, but predictive. That’s the difference between a simulation that’s “interesting” and one that’s indispensable.
We don’t just start a project by importing a CAD file. Our approach is built on a systematic foundation of verification and validation developed from years of seeing where simulations go wrong. It’s a methodology that forces us to ask the hard questions upfront, ensuring the final result is robust and reliable.
The most dangerous words in CFD are “default solver settings.” Using a one-size-fits-all approach is the fastest way to get a plausible-looking, but physically incorrect, result. We tailor every aspect of the simulation setup—from the turbulence model to the discretization schemes—to the specific physics of your problem.
A simulation’s result should be a function of the physics, not the mesh density. That’s why a grid independence study isn’t an optional extra for us; it’s a mandatory first step. We systematically refine the mesh and run the simulation until the key results (like pressure drop or lift coefficient) stop changing. This is the only way to be certain that the solution is not a numerical artifact.
Where the geometry allows, we prioritize structured hexahedral meshes over automated tetrahedral ones. Why? Because hex meshes often provide higher accuracy for fewer cells, leading to more stable convergence and more precise resolution of boundary layers—the critical region where the most important physics happen. ⚙️
Aspect of Simulation | The “Quick & Cheap” Approach | CFDSource Engineering Standard | Why This Is Non-Negotiable For Us |
Meshing Strategy | Automated Tetrahedral Mesh, default sizing. | Geometry cleanup, targeted local refinement, Hex-core or full Hexahedral meshing, and a mandatory Grid Convergence Index (GCI) study. | To eliminate the mesh itself as a source of error. The result must be independent of the grid count. This is fundamental to numerical accuracy. |
Turbulence Model | Standard k-ε for everything. | Selection based on Reynolds number, flow characteristics (separated, swirling), and wall treatment. Often SST k-ω for aerospace or Reynolds Stress Model (RSM) for complex anisotropic flows. | Choosing the wrong turbulence model gives you garbage results, fast. k-ε fails badly in adverse pressure gradients. SST k-ω is superior for boundary layer separation prediction. |
Solver Settings | Default convergence criteria (e.g., 1e-3). | Custom convergence criteria based on monitored integral quantities (e.g., drag, mass flow rate) stabilizing, not just residuals dropping. Double precision solvers. | Residuals are a poor indicator of true convergence. A solution is converged only when the quantities of interest are stable. This prevents premature termination of the simulation. |
Near-Wall Treatment | Standard Wall Functions (assuming y+ > 30). | Mesh resolved to the viscous sublayer (y+ ≈ 1) where necessary, or careful application of appropriate wall functions when a fine mesh is computationally prohibitive. | The near-wall region dictates skin friction, drag, and heat transfer. Getting this wrong invalidates the entire simulation for many applications. There is no middle ground here. |
A simulation without validation is just an opinion. After we achieve a converged and grid-independent solution, we benchmark our model against a known quantity. This could be experimental data you provide, wind tunnel data from a similar case in a research paper, or established empirical correlations. This step is what turns a simulation into a verified engineering tool you can trust. ✅
For extremely novel problems where direct validation data is scarce, a different level of scrutiny is required, sometimes involving collaboration with a specialized Fluid Dynamics Consultant to design a targeted validation experiment.
We’ve heard the horror stories: a project is outsourced and weeks later, a single PDF report lands in your inbox with a final number. No raw data, no explanation of the assumptions, no insight into the process. If you can’t interrogate the process, you can’t fully trust the outcome. That’s not how we operate. We believe our clients are smart people who deserve to understand the “how” and “why” behind their results.
Our final deliverable isn’t just a folder of contour plots and data files. It’s a full engineering report that walks you through the entire journey. We document the CAD cleanup, meshing strategy, boundary conditions applied (and why), solver settings, convergence history, and a detailed post-processing analysis. You’ll see the good, the bad, and the ugly of the simulation process. This transparency means you can defend the results to your boss, your professor, or your investors with complete confidence. It’s the kind of detailed documentation you’d expect from top-tier CFD consulting companies.
Your intellectual property is the lifeblood of your business. For our academic clients, originality is the cornerstone of their research. We treat this with the seriousness it deserves. There is absolutely no ambiguity in our policy.
Before a single file is exchanged, we execute a mutual Non-Disclosure Agreement. This isn’t an afterthought or an option; it’s the mandatory first step of any engagement. Your project’s details, your geometry, your data—it’s all held in the strictest confidence. For students, we guarantee that your project is built from scratch for you and you alone. We will never resell or repurpose thesis or dissertation work. Period.
While we can tackle a vast range of fluid dynamics problems, our deepest expertise lies in a few key areas. We are not a generalist firm; we are specialists.
We keep the process straightforward, so you can stay focused on your project goals.
Simulation Stage | Common Industry Pitfall | Our Commitment to You |
Initial Consultation | A sales-focused call that overpromises and under-delivers on technical detail. | A peer-to-peer technical discussion with an experienced engineer. We’ll tell you if CFD is not the right tool for your job. |
Project Updates | Radio silence for weeks, followed by a sudden “final” delivery. | Scheduled, transparent updates at critical project milestones. You’re never in the dark. |
Results Delivery | A data dump of files with little context or interpretation. | A comprehensive report PLUS a knowledge-transfer session to ensure you understand and can use the results effectively. |
Post-Project Support | The project is “closed” and further questions are ignored or billed extra. | We stand by our work. Reasonable follow-up questions related to the delivered report are always welcome. |
