Consolidated Compartment Fire Model (CCFM) Computer Code Application CCFM.VENTS. Part 4. User Reference Guide (NISTIR 4345)



Glenn P. Forney, Leonard Y. Cooper, W F. Moss


A project was carried out at The National Institute of Standards and Technology (NIST) to study the feasibility of developing a new-generation, multi-room, compartment fire model computer code, called the Consolidated Compartment Fire Model (CCFM) computer code. The ideas was that such a code would consolidate past progress in zone-type compartment fire modeling, and allow readily for integration of future advances with the greatest possible flexibility. The project lead to the development of a prototype multi-room CCFM product called CCFM.VENTS. This is Part 4 of a four-part report which documents the above effort. The main objective of this Part 4 document is to document the use of CCFM.VENTS. Its capabilities and limitations are described. A simple two room tutorial is presented to get the user quickly acquainted with the input requirements of CCFM.VENTS. Each CCFM.VENTS command is described. Finally, a program for plotting CCFM.VENTS data is presented. This program runs on an IBM-PC or compatible with a VGA graphics monitor. The other three parts of this report are: Part 1: Technical Basis; Part 2: Programmers Reference Guide; and Part 3: Catalog of Algorithms and Subroutines.
