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.

Guts of CFD: Interpolation Equations

The core of all calculus problems require us to consider something infinitely small. Ask a computer to ponder the concept of infinity and watch its circuits fry. If we want to solve the equations of computational fluid dynamics (CFD), we need a way to fake calculus. This impacts the stability, the mesh quality, and the ultimate simulation quality. Enter interpolation equations.

Guts of CFD: Transport Equation

What is the utility of a transport equation? What do they achieve? Transport equations form the fundamental language of computational fluid dynamics (CFD). CFD engineers use them to communicate ideas, program CFD software, and diagnose problems with their simulations. But they only work if you understand the language. Today we explain transport equations and the significance of their terms.

Imagine Your Ship Without Limits

Demand More from Your Vessel

The maritime market constantly drives to tighter margins, and vessels that hold the status quo go extinct.  Modern owners need to demand more from their vessel.  Greater freedom from of cargo load limits.  Improved crane capacity.  Lighter hulls with lower build cost.  And lower fuel consumption.  If you don’t ask for better performance from your vessel, your competitor will. 

DMS sees the potential to improve ships.  We improve your business by pushing against vessel operating limits.  By conducting our own targeted research and development, DMS cultivates the science to push back boundaries and achieve more.  At DMS, we challenge you to see beyond the current restrictions of your ship.  Instead, ask what vessel capabilities you require to achieve your business goals.  DMS can help you achieve those goals.

Automation Achieves More

DMS believes in continuous improvement for ships, and for our own business.  We employ computer automation to constantly improve efficiency on a wide scope of tasks.  Computer automation can reduce the time of a task from weeks down to days.  When other firms spend time typing at spreadsheets, DMS has a chance to revise the design, and identify improvements.  Let the engineers get more out of your vessel, and let the computers run the math.  Then everyone wins. 

Extraordinary Solutions

Automation does not limit us to just the routine work.  Occasionally, we all want something truly unique.  In these cases, DMS offers advanced engineering tools to break into new territory: 

  • Finite Element Analysis (FEA)
  • Computational Fluid Dynamics (CFD)
  • Genetic optimization of concept designs
  • Composite material engineering

We give you the freedom to imagine a better option.  But you still benefit from our groundwork in efficiency driven design.  Many premium projects include large portions of routine engineering.  We save cost on the routine, leaving you more budget to focus on the extraordinary.

You Call the Shots

At DMS, we work closely with the foremost expert for your vessel:  you.  We don’t force you into one vessel class.  Instead, we design to match your business.  No one else understands your business needs better than yourself.  We invest the time to break out of preconceptions and customize each vessel as the best asset in your business arsenal.  You get to decide what matters, and we listen.

This focus on your needs also eliminates many crew frustrations.  The vessel operators and managers demonstrate an instinctive expertise that we gratefully utilize.  The little details matter.  Sea yarns transform into design suggestions.  Your suggestions turn into design improvements.  Efficient ship designs revolve around efficient crew.  At DMS, the design process revolves around the end user, you

Your Advisor and Partner

DMS develops partnerships with our clients, based on mutual respect.  Long before our clients need our services, we offer free education about ship design topics.  Informed clients are better armed to make the best decisions.  And we listen.  We ask about your business and ships; we anticipate your needs.  Our partnerships grow from respect, not a mere exchange of money. 

And DMS will be ready to help on your next challenge.  We offer engineering services, free educational articles, and more.  Contact us for free general advice to prepare for your future needs.  Or get a quote for your next project to get it done right the first time.  At DMS, every ship deserves a better future. 

Recommendations

Datawave Marine Solutions took the time to understand our project and worked with us to develop an analysis package that fit our budget and our engineering needs. Reports were detailed with high quality graphics, data limitations summarized in plain English, and most importantly – everything was delivered in a timely manner. 

Calendar Marine

I’ve known Nicholas for a few years professionally and he is extremely knowledgeable in many aspects of Naval Architecture, FEA, CFD, programming and engineering in general.  Every time I have spoken to him I learn something new, so he is constantly improving his skills (if you follow him you learn from his posts).  If I were looking for a consultant in his field, I’d definitely hire him.
