FDS+evac dies on slice file creation

[gforney]

I'm developing an evacuation addition to an existing (and working) fds file. Per instructions
in the fds+evac manual, I attempted to create a pressure slice file to examine the
evacuation flow field. The pressure slice works (job runs to completion at T=1 s) if
I don't add the EVACUATION=.TRUE. If I add the EVACUATION=.TRUE. to the SLCF input,
the program dies with an access exception:

Well, 

&SLCF PBZ = 1.000, QUANTITY = 'VELOCITY', VECTOR = .TRUE., EVACUATION=.TRUE. / 

should work. But it might be true that the pressure does not work.
It has been many years since I last tried to see the pressure slice
for evacuation meshes. I just see the flow vectors.

But I'll check why the error message appears with pressure slice.

The problem was that PRESSURE_ZONE array was not defined
for evacuation meshes. Now it is. Now the flow vectors
can be colored with the pressure (quantity = pressure and
vector = true). No pressure slices can be seen. The present
Smokeview shows (load/unload menu) only vector slices for
evacuation meshes and this will be so. Well, later I might
add slcf output, e.g., for agent density, but not now.

The SVN 7700 version has this "bug" fix. 

TODO: Update manual (actually, I'm totally rewriting it
for the "fds6" style user input for evacuation).

TODO: Add checks for the SLCF and evacuation meshes,
accept only VELOCITY and PRESSURE. Other outputs do
not need these checks, because they do not have the
optional keyword EVACUATION= true/false.

I'll change the status to fixed, I have added the SLCF
input check to my todo-list, so I'll remember it.

Thanks for not just replying that I was being stupid ... I was though.  I edited an
existing slice to get the evacuation slice and neglected to change the pressure to
velocity.  I did actually mean to use velocity so do whatever you think is appropriate
with the code.

Attribute this to new FDS+Evac user stupidity.

Well, let's close this Issue. The only thing I could do
would be to add some user input checks, but that is in
my ToDo list for the evacuation inputs already.
