The leading industry graphical user interface for Fire Dynamics Simulator (FDS), PYROSIM, is recognized for its quick, reliable and precise simulation of complex fire models. It enables design teams to create complicated and cost-efficient designs in the preliminary stage without compromising desired level of fire safety. The objective of this Workshop is for engineers to gain an understanding of fire dynamics and fire modeling. The guided hands-on workshop will help you to familiarize with the graphical interface and work towards customizing and prescribing your own fire scenarios.
