Basics on FDS Output and Gas Burner HRR | Getting Started with FDS

An overview over the basic FDS output is provided, with focus on the "CHID.out" and "CHID_hrr.csv" files. Secondary outputs, like the "CHID_cpu.csv", "CHID_steps.csv" and "CHID_git.txt", are covered briefly. Using the "CHID.out" and "CHID_hrr.csv" files, the heat release rate (HRR) of a gas burner is assessed. Specifically, in context of using the heat release rate per unit area (HRRPUA) parameter for surfaces in the Fire Dynamics Simulator (FDS). This is a Fire Dynamics Simulator tutorial.
