I have run FDS for a case with these two parameters. Temperatures are lower than the same case with SUPPRESION=.FALSE., which make sense. However, in the case with suppression, at some point along the temperature trajectory, temperatures starts to increase, but still much lower than the case without suppression. I suspect this anomaly comes from unburned fuel gas that have found enough oxygen in the field. Would you agree? I noticed manual suggest the parameter \"AUTO_IGNITION_TEMPERATURE\" be used along with a form of heat/ignition source. Would HRR curve be enough for the source?\r\n\r\nAlso, FDS does not make any change in HRR curve with suppression which looks to me questionable. I would appreciate your thoughts on this point.\r\n\r\nRegards,\r\n\r\nSR\r\n  \r\n"}}
