Need Help for Risk Analysis with DNV's Phast Risk Software

[Sanjay kumar G R]

Dear Sir

First of all I would like to thank you for your reply.

There is a problem even if I approach as you said. The software has the material upto C8 only, i.e. n-Octane.
In this case, please let me know if there is any other solution.

Will be waiting for your reply.
Thank you

As said, I suggest if you know using C8 you introduce an error then be sure you're going to the safety side. If you are doing fire calcs check if the heating of combustion and flame temperature of C8 are close or greater to those of C12 then use C8. In the latter case the result will be overestimated but safe.

Alternatively, more precise if you could create your own custom material e.g. copying the C8 properties into a named "diesel" record and modify those physical parameters that most affect the fire results (u can use the PHAST tutorial or the yellow book as support to see what physical parameters are revevant in fire calcs)

Thank you so much!

This might work, i have just tried it.
Wish newer version of the software would over come these kinda problems, after all such a big software, why cant it provide maximum number of materials?

Anyways, thank you for your help.
Hope I'm gonna present it well. []
