Simulation and Analysis of Fire Escape Scenarios Based on Computer Visual Modeling and PyroSim Computer Simulation

With the progress of technology, various computer visualization and simulation technologies have been rapidly developed. Among them, Building Information Modeling (BIM) takes all the relevant information data of the construction project as the basis of the model, carries out the establishment of the building model, and simulates the real information that the building has through the digital information simulation. PyroSim is the software developed based on FDS software, which is specially used for the dynamic simulation of fire simulation. Combining the advantages of the two, this paper integrates BIM in PyroSim, realizes the fire simulation based on BIM, gets the fire simulation information, and thus establishing a complete set of fire simulation method for high-rise buildings based on BIM. And the combination of virtual reality technology allows people to experience the fire in person and improve the fire prevention awareness and response ability.
