From the 1st of June 2004 the building regulations was changed from only prescriptive fire protection to also include a function based option. With the function based fire protection, CFD simulation can be used to document the fire protection level. In order to use CFD for fire simulations it must be ensured that the CFD software is capable of modelling the real world, which is studied in a validation investigation.

The purpose of this report is to investigates Fire Dynamincs Simulators (FDS) ability to simulate the NFSC2 experiemt. A sufficient setup of FDS is determined in a parameter study, where different parameters impact on the results and computational time are judged. The recommended setup from the parameter study is used to a validation study of FDS with the NFSC2 experiment.

Based on the results seen in the parameter studies and in the validation studies, it is found that FDS is capable of reproducing the transient fire induced phenomenon from the NFSC2 experiment, in the most cases within the expected accuracy and in many cases within the experimental uncertainty with a prescribed HRR.
