Simulation Software

Rockets/landers arrive on the Moon with supersonic speed and impact lunar regolith. There is no reliable software to computationally simulate in an effective way the supersonic plumes escaping from these rockets/devices. A Large Eddy Simulation (LES) model and...

With self-driving vehicles poised to take the road, how can today’s engineers prepare themselves to support an autonomous future?

How do you regulate a system that, in effect, is learning as it goes?

Exhaust plumes emanating from smoke stacks at power plants or other industrial facilities can have adverse impacts on local aviation during periods of calm winds. Adverse impacts can be exacerbated if the temperature is low or the atmosphere is unstable. While low oxygen concentrations and elevated temperatures inside the...

A reader asks our expert: As autonomous vehicles enter the market, where are the weak spots in simulation?

The nation's aging infrastructure requires massive investment. Imagine if engineers could build structures with materials that do not degrade over time. A simulation technique was developed that could help engineers do just that.

As the number of channels, or operative sites, increases in present and future ground special power (GSP) development efforts, the amount of hardware required to test development codes becomes substantially expensive. By simulating/emulating the hardware, code...
