ANSYS provides several CFD models which are designed for simulating fire growth and suppression. The models can be applied in both steady or transient fires.

| Time lapse sequence of fire growth and suppression in a ship engine compartment using fine water sprays. The fire started in two pans on the floor which contain heptane fuel. The fire is allowed to grow for 90 seconds before 18 fine water spray nozzles are activated on the ceiling. Ten seconds later, the fire is extinguished. | ||
ANSYS is also active in the fire research community, developing and testing new models for different types of fires and fire scenarios including buildings, tunnels and open flames.
ANSYS CFX software has been used to analyze wind effects on an oil-pool fire in the process module of an oil platform. The aim was to calculate the external pressure levels, smoke concentration and visibility around temporary safe refuges and to determine the extent of smoke ingress and therefore the integrity of the refuge. This type of study allows quantitative assessment of the conditions to which rig personnel and equipment would be exposed in the event of an accident. Parametric studies are easily performed, providing a comprehensive understanding of safety matters under all conditions, such as varying wind speed and direction.
