AGL_SLICE Velocity Over Terrain with Obstructions

[gforney]

FDS Version:6.2.0
Smokeview Version/Revision: 6.2.2
Operating System: Windows 7

I am trying to simulate flow over terrain with obstructions. When I try to use the
AGL_SLICE command with flow velocity I run into a problem visualizing the AGL_SLICE
files in Smokeview. I have tried using the slice files with a flat terrain and with
the terrain that I am trying to study. In both cases, the flow shown around the obstruction
is not what would be expected. In addition, at certain heights, the location of the
obstruction in the slice file is shown in an incorrect location.

We'll take a look at the case.

I'll take a look at this.

The smokeview posted fixed the problem of visualization of flow around obstructions.
However, I found a different issue when I set the location of 100 feet above ground
level. The slice file shows the obstruction impeding the flow well above where the
obstruction should not have any impact on flow.

I uploaded test smokeview's that should work for cases that DO NOT have NOTERRAIN=.TRUE.
on an &OBST line.  FDS at present is not outputting data correctly in regions above
where &OBST's with NOTERRAIN=.TRUE. are defined so slice files and levelset cases with
this option will not be correct.

test smokeviews, revision 22783, are located at
