Here's the output with zero duct volume (change dl(*) to 0.0_eb at line 1043 of
input.f to toggle volume on and off. This impacts the calculation in
flowfan.f90 around line 575. Important variables include the amount filtered
(variable name filtered), tracet, traces, ...

Here's the version of fire.f90 (as of r1647) that I modified to create the fake
trace species in a totally closed system without a fire

This also seems to impact one of the verification tests:
fire_filter_efficieny.in in Verification/Mass_Energy_Balance. With the duct
volume dl(ndt) set to 1, this case doesn't fail..
This case runs in a release compile but fails with a DASSL error in a debug
compile. Since it's filtering, it should all be part of the same issue.

Here's another file that acts differently when changing the duct length.
Validation file Validation/NIST_NRC/Test_16/NIST_NRC_T16.in fails to converge
to a solution when 1) dl(ndt) =0.0_eb (line 1043 in input.f90) and when
compiled with the 64-bit command line build. It works fine if either dl(ndt) =
1.0+eb or any other compile type.

OK. Changing the leakage (r1655) fixes the problem so you don't get a failure
with 64 bit for NIST-NRC_T16.in. To get it to fail, change width of leak to
10.17 m
