Welcome to the Summer 2003 Issue of the
Published quarterly, our goal is
to provide information that helps you get the most out of
GoldSim. We also hope that the Newsletter can act as a vehicle
to build connections between users within the GoldSim community.
Each newsletter delivers the latest
GoldSim news, as well as a number of regular items. This one
includes tips from the GoldSim developers, a list of new models
added to the GoldSim Model Library, a list of new GoldSim
Knowledge Base articles, and a description of new features
that the GoldSim Development Team is currently working on.
Each Newsletter is archived on our website so you can revisit
Since this newsletter is for you,
we encourage you to send us your comments and contributions.
If you send us a contribution and we use it, we will acknowledge
you in the Newsletter. Send your contributions to email@example.com.
The GoldSim Technology Group
Second Annual GoldSim User Conference a Success
The Second International User Conference was held on June
17-20 at the Washington Athletic Club in Seattle, Washington.
This 4-day event had 50 attendees from 9 countries. Almost
all the attendees participated in either the two-day Basic
GoldSim Concepts course or the one-day Advanced GoldSim course
held prior to the User Conference. The conference included
19 technical presentations. The presentations are available
(in PowerPoint) from within the GoldSim Resource Center.
GoldSim On-Line Help System Released in May
In May 2003, we released an extensive context-sensitive on-line
Help system for GoldSim. The Help system essentially contains
all of the information that is currrently in the printed User's
Guide, but adds powerful navigation capabilities (including
keyword and full text search, related topics lists, and hyperlinked
To complement the Help file, the User's Guide was also updated,
with the primary change being the addition of detailed index
(with over 1000 entries). If you have an older version of
GoldSim (without Help), you can download the Help file from
the GoldSim Resource Center.
Wired Magazine Article Discusses GoldSim
GoldSim was discussed in the April 2003 issue of Wired Magazine.
GoldSim is discussed in an article entitled
or Die at Yucca Mountain" by David Ewing Duncan.
The article describes the U.S. Department of Energy's proposed
repository for the nation's spent nuclear fuel at Yucca Mountain,
The article discusses the technology that the Department
of Energy has employed to determine whether or not the waste
can be safely disposed of at the site. GoldSim provides the
computational framework to carry out this analysis, and is
the primary tool that is being used to predict the long-term
performance of the facility.
GoldSim Featured in Manufacturing Economics Textbook
Several GoldSim models are included in the manufacturing
economics textbook "Manufacturing in Real-Time: A Guide
for Managers and Engineers in an Age of Smart Machines"
by Gian Frontini and Scott Kennedy.
The book was published in May 2003 by Butterworth-Heinemann
and is available at Amazon.com.
The authors created a series of GoldSim models to illustrate
key concepts discussed in the book and included the files
and the GoldSim Player (a free run-time version of GoldSim)
on a CD which is distributed with the book.
The GoldSim development team is hard at work preparing for
the release of version 8 in September. In addition to adding
and polishing numerous little features, here are some of the
bigger things you can look forward to:
A new Reliability Module, which will be bundled
and available at no additional charge with GoldSim Pro.
This module adds some versatile and powerful new elements
to help simulate the performance of complex engineered
A new Convolution element, which lets you project
the future consequences of events in your model. For example,
if you sell 1,000 new cars this month, what are your future
liabilities for warranty repairs? Convolution lets you
project the consequences of your model's history into
Auto-layering. Ever get annoyed by influence-lines
getting in front of your elements? We're adding an option
to automatically push graphics to the back, put influence-lines
in the middle, and keep elements on top of your graphic
Container-specific timesteps. If part of your
model (e.g., a container) requires short time steps, but
the rest doesn't, you will be able to specify shorter
steps just for that part.
More graphics formats will be supported. You will
be able to insert more types of graphics into your models,
and GoldSim will compress and manage them more efficiently.
Contaminant Transport-the CT and RT modelers will also
get some new capabilities.
A new 'direct transfer' option for mass flux
will be added to the existing advective and diffusive
capabilities. This new option provides a very general
first-order transfer process for cases that aren't
advective or diffusive.
Contaminant species can have up to four daughter
If you're interested in helping us to test any of these capabilities,
please send us an email at firstname.lastname@example.org.
You may have to put up with a bug or two, but you'll be able
to provide input and your assistance will be greatly appreciated.
We'd also appreciate any suggestions that you might have for
new GoldSim features!
