Save the Date: 2007 GoldSim User Conference and Training
Seminar in San Francisco, October 23-26
We are pleased to announce that the 2007 GoldSim User Conference
will be held on Thursday and Friday, October 25-26 in San
Francisco, California. Just prior to the conference,
we will offer two concurrent training seminars: Basic GoldSim
Modeling on October 23-24, and Advanced GoldSim Modeling on
October 24 (with topics chosen based on registrant's suggestions). The
conference is a terrific opportunity to increase your
knowledge of GoldSim, ask questions directly to GoldSim developers,
and network with other GoldSim users.
The agenda for the conference includes sessions to improve
your GoldSim skills, presentation of a number of papers from
our most experienced and knowledgeable users, a poster session
so you can see how other users apply GoldSim, and a model
contest so you can show off your GoldSim skills. We will also
be featuring a group modeling exercise this year that
promises to be both fun and highly educational. As always,
we have scheduled several social events in the evenings so that
you can enjoy the sights of one of the world's most vibrant
cities while networking with fellow GoldSim users.
Conference details (including agenda, venue, costs, and a
call for papers), along with a registration form will
be available within the next week on our website. We
will send out a short note to everyone on the Newsletter list
when this information is available.
Addressing Global Warming: Applying GoldSim to C02 Sequestration
Mounting evidence of global problems associated with excess
atmospheric CO2 requires a solution that can be implemented
quickly, safely, and economically. Given these constraints,
researchers worldwide have concluded that geologic sequestration
is the best available option. Los
Alamos National Laboratory (LANL) has developed a system-level
model for geologic sequestration that tracks the fate of CO2
and is designed to include all associated risks. The
system-level CO2 sequestration model, called CO2-PENS (Predicting
Engineered Natural Systems) uses GoldSim
as an upper level platform. This article briefly discusses
LANL's modeling framework.
Version 9.6 of GoldSim Released
Version 9.60 of GoldSim was recently released. This
new version has a number of new features, including:
The Material Time Series and Information Time Series
elements have been retired, replaced by a single new Time
Series element that is simpler and more versatile.
Existing models with Material or Information Time Series
elements will be automatically converted. Among
other capabilities, the new Time Series element is capable
of recording a time series that can be ‘played back’
Options have been added to the Simulation Settings dialog
allowing users to use calendar-based timesteps (monthly,
quarterly, or annual) as opposed to constant timesteps.
Results inside of SubModels can now be saved and viewed.
The user interface and functionality for External elements
and External Pathways (in the CT Module) has been enhanced.
Among other improvements, external functions can now input
and output Time Series.
In addition to these major changes, a large number of additional
enhancements were also made to GoldSim to improve its overall
performance and usability. A more complete list of changes
can be found in the Release
All current members of the GoldSim Subscription Program can download Version 9.6 right now
from the GoldSim
Resource Center (GRC).
Free GoldSim Reliability Elements
Did you know that all GoldSim versions provide
access to the Reliability Learning Edition, allowing
you to use up to ten Reliability elements? The Reliability
Module (RL) allows you to probabilistically simulate and
analyze the reliability and performance of complex engineered
systems over time. For example, with RL, you can predict the
reliability of a new mine conveyor system, evaluate the safety
of a proposed space station, or determine the fault tolerance
of a new network topology. You can access RL elements simply
by creating a new model. For further examples, you can download
RL models from the GoldSim Resource Center.
GoldSim Reliability Webinar
GoldSim invites you to an Introduction to the Reliability
Module webinar on April 26th, 2007 at 8:30 AM PST
(-8 hours GMT). Andrew Burns will discuss the basic features
of the Reliability elements and show how they can be used
to simplify modeling of system states in your GoldSim models.
This webinar is a great way to see how you might take advantage
of the Reliability Learning Edition (included with GoldSim
Pro) in your own models. Click
here to send an email to Tim Schmitt to receive an invitation.
Depending upon the response, a second time may be added to
better accommodate attendees in Asia and Australia.
Send us a note and we'll let you know!
GoldSim and Sandia Sign Partnering Agreement
GoldSim Technology Group recently signed a four-year Cooperative
Research and Development Agreement (CRADA) with Sandia
National Laboratories (Sandia). The objective of
the CRADA is to help create the next generation software package
for evaluating complex engineering problems. This collaborative
effort will provide an advanced computing solution that directly
supports Sandia’s mission as the Lead Laboratory for
the United States Department of Energy's Yucca Mountain Project
(the evaluation of a potential high-level radioactive waste
repository at Yucca Mountain, Nevada). In addition to
supporting Sandia's ongoing efforts at Yucca Mountain, the
collaboration may also have direct benefits for a wide variety
of other applications of interest to both Sandia and GoldSim,
including simulation of water resources problems, and engineering
reliability analysis for energy, space and defense systems.
Running Models Using Calendar-Based Timesteps
GoldSim allows you to run models based on either elapsed
time or calendar date/time. Running calendar date/time
models, however, can be a bit tricky, since calendar-based
models are complicated due to the variability of the basic
time units (e.g., the number of days in a month changes for
each month). This short article discusses a new GoldSim feature
that makes it easy to create calendar-based, non-constant
(e.g., monthly, quarterly) timesteps.
Beyond Version 9.6
We are already working on a number of items for our next
release (targeted for late 2007). One of our major efforts
currently revolves around Dashboard Redesign.
An increasing number of users rely on models with Dashboards
(control panels that allows others to easily edit and run
your models). In response to this, we are currently implementing
a redesign of our Dashboard Module to incorporate user requests
and add a number of powerful new features.
As always, we encourage user requests and suggestions. If
you have specific feedback, please contact us at email@example.com.
