Hydrostatics Modeling

Hydrostatics modeling is the first step in any stability analysis.  We construct a model of the vessel that includes all relevant details for a stability analysis:

  • Hull surface
  • All tank definitions
  • Locations of all downflooding points
  • Sounding tubes for tanks
  • Section modulus definition along hull length
  • Loading conditions
  • Draft mark offsets

If the model gets used in a damage stability analysis, we add further details:

  • Internal compartmentation
  • Cross flooding links
  • Margin line definition
  • Bulkhead locations (for floodable length analysis)
  • Damage conditions

Just the stability model can answer many key questions regarding vessel floatation.

  1. Hydrostatic properties
  2. Tank capacities
  3. Tank sounding tables
  4. Floodable length curve
  5. Longitudinal strength comparison

At DMS, we use the Maxsurf set of stability products.  These products can import GHS and Rhino models.  Plus they bring several other advantages. 

  1. Visual output to show the exact vessel state
  2. Direct program output into MS Word: less time formatting reports
  3. Automatic generation of lines plan from hull model
  4. Automatic generation of Rhino geometry file from hull model
  5. Many more. . .

Efficient hull modeling makes for efficient engineering.

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.
