REMARKS • Modeling of
changing ventilation conditions o Do not place openings/closings on the boundary of computational domain o Simplified model in FDS is very good start o Stability issues when configuration changes too much at once • It is very important that fire tests consider the needs of model validation when selecting an instrumentation scheme. • Modeling tools are the key to advancing fire safety research and engineering o Data rich o Efficient and economic COPYRIGHT © 2013 UNDERWRITERS LABORATORIES INC.
