Becoming an Engineering Hero – Exploring the Great Wall of China

The Chinese believe that you can’t be a true hero unless you climb the Great Wall of China. As someone who yearns to be a hero in everyone’s eyes, (much less the eyes of 1.3 billion Chinese folks), I set out to conquer the wall earlier this month during a vacation to Beijing, Xi’an and Hong Kong.

First, a grossly abbreviated history of the Great Wall: While several small walls were constructed as early as the 8th century BC, it was Qin Shi Huang, considered the first emperor of China (and the body protected by the equally amazing terracotta warrior army), who devised a large wall to protect his territory from northern invaders. With the help of several other dynasties, the wall was modified over several thousand years, leading to a modernization effort by the Ming Dynasty in the 14th century. Continue reading

Convergence of the Design V: Simulating the Simulator

During October’s Engineering Simulation for Military Technology Conference, just outside Washington, D.C., there was much discussion of the tools and techniques for simulating the depth of the design V — from requirements planning, through system of systems, through systems to full physics-based simulation. A clear standout theme from the presentations and interactions was an increasing convergence of these different scales of tools. From the top level there is downward pressure to incorporate increased fidelity in the models used to support the systems view and that this needs to be derived from a physics-based understanding. From the lower levels there is upward pressure to extract physics-based reduced-order models and robust design envelopes that can be used to feed into higher-level systems models. This is moving beyond the realm of discussion and is becoming reality. One example of real-world application is the use of physics-based simulation to develop better helicopter flight simulators — in effect simulating the simulator!  Watch and listen to the team at the University of Liverpool in the U.K. talk about this work.

Should Simulation Remain a Secret?

For those of us in the simulation business, it’s easy to forget that the vast majority of people who use products that we contribute to have no idea the role that simulation plays. Consider recent this article from TechRadar that highlights technology that most people never think about – although it regularly impacts their daily lives. Continue reading
