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.

Practical CFD: General Approach

Just fresh out of college, and the boss assigned your first project for computational fluid dynamics (CFD). You are excited. You can’t wait to begin the challenge. You sit down at your computer, start up the CFD software . . . and freeze like a deer in headlights. How to begin? What to do first? Today we discuss the general workflow for a CFD project and highlight some general modeling advice.

CFD Workflow

What happens behind the curtain when the CFD engineer goes to work? What goes into making a CFD simulation? As a project manager, you need to understand the workflow of a CFD project; this helps you plan the project and track budget expenses. When we understand the workflow, we know the right questions and can anticipate project delays.

Which CFD?

Is there anything that CFD can’t do? Practically speaking, we can achieve the result, but you may regret paying for the answer. Several CFD projects involve combinations of different CFD methodologies. Combined together, they evolve into a major project risk. Gain some insight about the risk factors for your next CFD project. Plan a strategy to minimize project risks so that you don’t get caught by combining unknown cost increases.

What is CFD

What is CFD? It uses the computer and adds to our capabilities for fluid mechanics analysis. If used improperly, it can become an incredible waste of time and money. With the right engineer, CFD can be cost effective, incredibly informative, and offer unparalleled flexibility. But what is this wonder of modern science? Learn more about this expansive tool.

Six Ways to Break the Ship

Why are ship structures so labor intensive to design? Engineers need to anticipate multiple methods of failure, which makes a lot of work. The trick of efficient structural analysis focuses on recognizing which methods of failure are likely in each scenario. This article reveals six major methods of structural failure, with examples of common applications. Because it will be the failure mode you didn’t consider that ultimately leads to catastrophe.
