Expert Witness and Forensic Engineering

Some of the most unique engineering projects result from forensic engineering.  DMS has extensive experience supporting multiple forensic engineering projects.  Beyond basic expert witness capability, we offer the ability to recreate the incident.  But not a simple animation.  We offer simulation.  A full recreation where every single second is supported by full calculation of real world physics.  Animations just convey stories about reality.  Simulations are reality.

Our advanced simulations allow us to recreate events leading up to the incident.  We can predict forces, play out potential scenarios, and simulate the sequence of events.  All this can be choreographed and presented in convincing video animations with simultaneous graphs or timelines.  Our simulations provide more.  They provide evidence, validated and quantified by science.

Reasonable Pricing

Did you know that many consultants double their billing rates to give deposition as expert witnesses?  At DMS, we charge the same billing rate, in court and out. 

Not sure if you need an expert witness?  Just want some general background on the technical issues involved?  We offer general advice for free.  Try before you buy and get a feel for the value we offer.

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.
