The Fire Dynamics Simulator (FDS), first publicly released in 2000, has recently undergone its fifth major revision. Since its first release, FDS has been applied in three major areas: basic research in fire dynamics, performance-based design, and forensic reconstructions of actual fires.
As its applications widen in scope, there is a need to develop new capabilities, while at the same time to verify and validate new and existing algorithms. This is a difficult task because the variety of applicable scenarios is vast and growing.

The Central Valley Arson Investigators association continued the tradition of providing outstanding training at their annual Advanced Explosive Recognition class. The training was held once again at the Tulare International Agri-Center grounds. This year’s topic was the history of the American criminal bombings. Guest speaker Ed Nordskog, LA Sheriff’s Department, lead the class through the history of American bombings, from the earliest bombings in America right up to the most current-day events.
While in the classroom, we were given a taste of what was to come in the afternoon on the range, a few large booms came from the range-site, and this, of course, sparked the interest of the attendees filling the room with anticipation for the afternoon’s activities. I’m not really sure if that was part of the scheduled shots, or if Frank just couldn’t wait to try out his handy work.
Thanks to Geary Baxter and his crew, everyone was treated to a hot dog lunch with all the fixings, chips, chili, and drinks. Shade covered bleachers were provided to keep the sun off the students during the demonstrations. The range was arranged with several props from mail boxes (fairly close to the bleachers), to two transit buses and an ambulance several hundred feet down range. And, of course, there was a pressure cooker, which was placed down range, so that we could see the effects of a device similar to the one used in Boston.
The students were given the count down, so they could get their cameras ready to capture the moment, “Fire in the hole, three, two, one”! Our very own Scotty Baker, the voice of the AER range, would call out when each prop was ready to be set off. This year had more than its fair share of silence when the charge was supposed to go off. After making our first run down range to get a closer look (and see the handy work of the Sheriff’s bomb team), it was clear what had happened, the fragmentation from the first explosions took out the six-pair lead-in wire. By the way, the trip down range was in a people mover provided by CVAI; these guys think of everything.
The class was attended by nearly one hundred and fifty students from police, fire, and evidence people from all over the state. There was even a fellow from New York City in the class (and I thought it was a long drive from San Diego). There was great representation from the CCAI elected officials; President Scotty Baker, First Vice-president Tom Peirce, Second Vice-president Eric Emmanuele, Director Dale Feb, and myself Director Troy Morrison.
Thanks to all the folks at Central Valley Arson Investigators for all their hard work!! Another great training class. We are all looking forward for what is in store for next year when the theme for the AER class will be “First Responders”.
Troy Morrison, PIO CCAI
