Pathfinder / Standard sample size in Monte Carlo Simulations
« on: April 20, 2021, 12:26:27 am »
Beginning from Pathfinder 2018.3, it is possible to run Monte Carlo Simulations to handle the uncertainties associated with the statistical distribution followed for occupant attributes. Is there any standard value for sample size that we can follow for fire in institutional buildings? Or any reference work from where we can get an idea about the choice of sample size for different scenarios?

Pathfinder / Visibility Threshold for tenability assesment
« on: April 20, 2021, 12:23:35 am »
For manually coupling FDS results with Pathfinder to introduce the speed reduction factor (https://support.thunderheadeng.com/tutorials/pathfinder/manually-coupling-fds/) it is also mentioned in the Summary section that a user can choose to completely prevent entry to a room by closing doors as an alternate way for incorporating the effects of visibility in movement. But no value of visibility is prescribed as critical or threshold at/below which the doors are to be closed. Is there any particular value for this or any reference works/studies that can guide us through this problem?
