CFAST Layout Smoke parameter

[Stefano Caroli]

Hi to all, how can I obtain  into CFAST Output file  smoke obscuration (%m) or measured density (mg/m3) as reported at page 87 of Volume 3 page 87 - Verification and validation guide ? 

Thanks for any suggestion

By default, smoke obscuration is in m^-1. Setting the "Validation Output" on the Output tab in CEdit or running CFAST with the -V option from the command line outputs smoke in mg/m^3.

If you run the file from CEdit, go to the "Output Tab," select the checkbox next  "Validation Output," then just click "Run" to run the file. Output for smoke should then be in mg/m^3.

To run from the command line, run the Windows Command Prompt (it's usually in the folder "Windows Accessories" on the Start Menu, or type "CMD" in the search box on the taskbar, change to the folder where the input file is, then run CFAST as described in Appendix D of the CFAST User's Guide with the -v option
