Advanced Analysis

DMS specializes in advanced analysis.  We possess extensive background in the theory and practice with a range of computer simulation and analysis techniques.  We have experience in multiple simulation software packages.   We learned the tricks of the trade to ensure efficient project execution.

More important, we are experts in practical and relevant analysis.  We don’t just report a string of useless numbers.  We explain their significance.  We relate the computer back to the real world.  We keep our analysis grounded in reality, focused on the important part:  your ship.

At DMS, we also know that computers can lie.  Simulation based analysis does not guarantee accuracy.  The computer happily produces garbage without the watchful eye of an experienced engineer.  DMS remains rigorous in our approach to simulation quality.  We routinely expand our library of validation studies in both FEA and CFD.  And we perform mesh independence studies on every single simulation.  Every simulation report includes a quantification of simulation error.  We tell you exactly how much to trust the simulation and what safety factors to apply.  This delivers ultimate confidence, not in the computer, but in the engineer controlling that computer.

Guts of CFD: Near Wall Effects

Turbulence does tricky things near walls. Boundary layers and laminar sublayers compact interesting flow patterns into a very small space. Small it may be, but experience proved we cannot ignore it. The boundary layer forms on the body, which is our object of interest, arguably the most critical region. Turbulence is most critical near the wall, and we need to consider near wall effects.

Guts of CFD: Turbulence

How we address turbulence is the defining feature of modern computational fluid dynamics (CFD). No modern computer has the power to directly compute the full details of turbulence (as of 2019). Instead, we make approximations and develop empirical models. What type of approximation, and which models should you select?

Guts of CFD: CFD Linear Solution

The heart of any CFD program is an extremely efficient linear algebra solver. But CFD equations are non-linear. How do we stretch the limits of linear algebra to accommodate non-linear CFD equations? How do we take the mathematics from one cell and apply them to millions of cells?

How to Design a Waterjet: Key Elements of Waterjets

What makes a waterjet work? What is the difference between a good and bad waterjet? Waterjets may appear to be brutes of power, but they rely on delicately balanced design equations. Learn the common elements that go into all waterjets and discover the best practices that you should expect from any decent waterjet design.

Practical CFD Modeling: Judging Convergence

CFD convergence is not an exact science. The CFD engineer relies on three tools to judge when a simulation finishes: monitors, flow patterns, and residuals. But none of these tools work 100% of the time. The well-trained engineer understands how to use these tools and how to combine them into a cohesive picture and reliably judge a converged CFD simulation.
