Bug in condensation of HF

[johodges]

Describe the bug
We were running a model to evaluate the capability of FDS to model the condensation of HF. From what I can tell in the user guide it should be possible since gas and liquid phase properties are included in prop.f90. However, when we run the attached model with the latest FDS we get a crash in radi.f90:495 because FDS is trying to grab refractive index data from a lagrangian particle but the class < 0 corresponds to species mixtures.

To Reproduce

Steps to reproduce the behavior:

1. Run the attached input file.

test_1c.txt

Thanks, we'll take a look.

Looks to me like @drjfloyd has this coded up only for water and fuel species.

@johodges For the time being, if you do not need radiation, the case seems to run with &RADI RADIATION=F/

[johodges]

Thanks, we'll go with that for now. We are planning to compare with some data we have found in the literature assuming that the functionality works. I'll let you know how it turns out.

I think the solution to this one is we need to add inputs for the refractive index to spec so the spec liquid properties can have them.

[drjfloyd]

This should work now.
