Support Policy
It has taken a long time for HEC-ResSim Version 3.0 to be released to the general public. This was due to the considerable number of “known issues” that needed to be addressed in both the computations and the user interface. Most of these issues have been corrected or user options have been added to help manage them. But no software package exists without bugs, both known and unknown. This page of the HEC-ResSim pages of our website will be used as a growing log of those issues that we knew of (at release time) or learn of (after release). Each entry in the log will include a descriptive title, the date it was entered, a detailed description of the issue, and, if possible, instructions for how to handle (or work-around) the undesirable program behavior or result.
If you encounter an issue that has not been documented below, please refer to our Bug Report page for instructions on reporting it.

Issue #3 -
Windows Vista/7 Support Updated: October 31, 2011 |
Problem:
HEC-ResSim 3.0 uses an embedded
Java Runtime Environment (JRE)
that is not supported under
Windows 7. Consequently,
HEC-ResSim 3.0 does not work
with Windows Vista/7.
Solution:
In order to use HEC-ResSim 3.0
with Windows Vista/7, you must
use a revised setup package for HEC-ResSim 3.0
that has a newer version of the
JRE embedded. Below is a
download link to HEC-ResSim3.0a,
which is supported on Windows
Vista/7. If you continue to have
problems with HEC-ResSim3.0a,
please report your issues to
hec.ressim@usace.army.mil.

Issue #2 -
Credit Storage option produces incorrect results Created: May 2, 2007 |
Problem:
The Credit Storage option (an
operational feature that allows
a reservoir’s guide curve to be
raised or lowered depending on
the available storage in
upstream reservoirs) is not
producing expected results. When
used, this option appears to be
modifying the top-of-zone curves
for all zones, not just the
curve that is identified as the
“guide curve”. In addition, the
changes being made to the zones
seems to indicate that the input
data in not being interpreted
correctly.
Solution:
At this time, a workaround has
not been identified. Use this
option with caution.

Issue #1
- Watershed size never shrinks, only gets bigger Created: April 26, 2007 |
Problem:
Watersheds just keeps growing,
even after old networks,
alternatives, and simulations
are deleted.
Solution:
This issue, and how to deal with
it, is described in a separate
document that we have developed
named “Cleaning
up an HEC-ResSim Watershed”.
