Combustion Simulation That is Good and Fast and Affordable

Impossible dreamThere’s an old project management adage that goes “Good. Fast. Cheap. Pick any two.” There are tons of websites and blogs about it. I’m particularly fond of this one about the designer’s holy triangle. Unfortunately, this holds true in the engineering simulation world. With “good” meaning “accurate,” you’re stuck with suboptimal choices: Good + fast = expensive; good + cheap = slow; fast + cheap = inferior. Product designers are stuck with good results that take too long or “directional” results fast. Good and fast just was not on the table. Continue reading

Using CHEMKIN Simulation Software for Complex Chemical Processes

As a new member of the ANSYS family, via the Reaction Design acquisition, I thought I would take the opportunity to give you a little background on the product line I represent — CHEMKIN.

The software had its beginnings at Sandia National Laboratories, as part of the U.S. Government’s response to the oil crisis of the 1970s. Scientists at Sandia began studying how to make more efficient, cleaner-burning engines, and they created software to simulate the complex molecular-level chemical reactions that take place during fuel combustion. In 1997, Reaction Design licensed that software from Sandia and evolved the technology into a commercial-quality software suite that enables engineers and scientists in microelectronics, combustion and chemical processing industries to develop a comprehensive understanding of chemical processes and kinetics.
