Why is fire modeling useful?
Computer-aided fire modeling is becoming more and more widespread in Hungary as well, and this is no wonder … After all, its benefits can be exploited not only in the field of fire prevention, intervention, firefighting and rescue, but also in the field of economy. The simulation provides accurate data, thereby facilitating design. You can save costs because the requirements and solutions become known at an early stage and not during implementation.
WHAT IS INCLUDED IN FIRE MODELING AND COMPUTER SIMULATION?
The purpose of analyzing the program and models is not to design, but to support design, verify the designed systems, demonstrate their effectiveness, and reduce investment costs.
We can take advantage of fire modeling if we want to optimize heat and smoke extraction, we want to know what heat-resistant steel structure we are designing in the building, and we can reinforce their ideas in case of individual design.
In detail about fire modeling
We use two types of software for the simulation.
The PATHFINDER program models the escape from a building and how long it takes to leave a building. The program itself is able to count on congestion and is able to take into account that a given room has several exits.
The FDS program was developed in the United States and spread from there around the world. It greatly contributes to the modernization and development of fire protection. With the help of a computer model we can simulate the given room, the conditions in them and the materials present there. We can analyze and observe several factors at once. The program itself facilitates the completion of existing engineering methods and can show a new path to the complex design of more efficient fire protection systems.
The program divides the space into cells and then simulates the changes in space following the assumed fire burning.
Once we have run the test and received the output files, we can view them with Smokeview developed by NIST. This makes it clear what processes would take place in the model we designed.
The basic data for the construction of the model are provided by the architect, mechanic, fire protection designer and fire protection authority. The resulting floor plans, layout schemes, branch plans, etc. based on this, the room is built as a proportional model. The information provided by the designers may include: blueprints of the building, properties of the materials, materials of the walls, plans for the design of heat and smoke extraction, and the characteristics and location of the extinguishing system in the room.
The aim of the program is to facilitate the design and construction, as well as to substantiate with values the suitability or unsuitability of the building to be implemented by the designers in terms of fire protection aspects. FDS can not only verify with values, but also be able to visually display whether a given building has been properly
