CFAST和FDS是目前国际上通用的建筑火灾模拟软件。为了更准确的模拟和预测建筑火灾情况,美国国家标准与技术研究院(NIST)于2011年开始,开展长达12年的研究计划。研究计划分4个阶段,主要是找出CFAST和FDS存在的不足并予以修正。同时,解决FDS和Smokeview中所有障碍物必须是线性气态数值 CFAST and FDS are the most common building fire simulation software in the world. In order to more accurately simulate and predict building fires, the National Institute of Standards and Technology (NIST) began its research program in 2011 with a duration of 12 years. The research plan is divided into four stages, mainly to find out the shortcomings of CFAST and FDS and to correct them. At the same time, solving all obstructions in FDS and Smokeview must be linear gas values
