Defense programs are mostly government-driven and financed on special funds with specific IT resources.

With our extensive CAE (Computer-Aided Engineering) solutions portfolio and long time experience in dealing with the French and US Defense Ministries, ESI Group is a major player in the CAE field.

Our solutions, our work ethics, and our organization (ISO 9001 certified) make us eligible for highly sensitive defense programs. ESI Group's simulation solutions allow the various enterprises partnering on a defense program to share compute models. Our solutions also enable easy and secure coupling with proprietary codes. ESI Group has proven experience in this type of CAE decision support system.

Sandia Corporation, a Lockheed Martin Company, has developed a hand-held chemical analysis system designed to be used by first responders for the detection of toxic agents. Sandia engineers worked with ESI Group to simulate fluid flow and chemical reactions through the preconcentrator with CFD-ACE+.
The simulation results showed that in the initial concept design flow rushes along the sides of the preconcentrator with poor wetting of the adsorbent pillars resulting in inefficient adsorption of analyte. Sandia modified the design by rearranging the pillars to improve wetting and optimize the adsorption and desorption phases.
