FDS

I thought FDS was a religious cult. Then I thought it was something like LDS latter day saints or maybe the fire dynamics simulator. (Fire Dynamics Simulator (FDS) is a computational fluid dynamics (CFD) model of fire-driven fluid flow. The software solves numerically a form of the Navier-Stokes equations appropriate for low-speed, thermally-driven flow, with an emphasis on smoke and heat transport from fires.)

But I honestly didn't think of FDS feminine deodorant spray. Until I searched FDS and a light comes on. Thank god for search. I better get out more. Thank-you for clearing that up for me.
