Saving Chart Styles. After modifying the appearance of a result chart, you may want to save the attributes of the chart (e.g., fonts, colors, headers) so that you can apply the same settings to another chart. To facilitate this, GoldSim allows you to save the attributes as a named chart style. The chart style can then be applied to other charts in your model, or in other models. To learn more about chart styles, look under "Chart styles, introduction" in the Index tab of the GoldSim Help system or the Index of the manual.

 

 

The GoldSim Knowledge Base contains articles addressing frequently asked questions, workarounds for known problems, and advice on applying GoldSim. The Knowledge Base is available from within the GoldSim Resource Center (GRC). A few of the recent additions include:


Article 37, 39, 40: Common registration problems that users have encountered

Article 38: Creating an external function DLL using Lahey Fortran 95

Article 41: Exporting a screen grab of the graphics pane

Article 42: Problem with exporting enhanced metafiles

Article 43: Navigating Containers using the keyboard

We encourage you to visit the Knowledge Base, as even expert users are likely to find useful information there.

 

 

The GoldSim Model Library allows GoldSim users to build on the experience and knowledge of others by sharing models. The Library is available from within the GoldSim Resource Center (GRC).

Within the last few months we have added a few more models to the model library, including:

Model 35: Convolution Integral for Simple Voltage Response

Model 36: External Function Example Using Lahey Fortran 95 Compiler

Model 37: Unit Hydrograph Application to Runoff Calculations

Model 38:Directing Events According to a Specified Discrete Distribution

Model 39:Generic Performance Assessment for a Shallow Waste Disposal Facility (an excellent model that illustrates how to build a realistic contaminant transport model in GoldSim - thanks to John Tauxe of Neptune and Company)

If you have a model that you think would be worthwhile to post to the library, please send it, along with text describing the model, to library@goldsim.com.

 

 

Welcome to the Summer 2004 Issue of the GoldSim Newsletter!

The mission of the GoldSim Technology Group is to provide state-of-the-art software, training and expert consulting to help you understand complex systems and make better decisions in an uncertain world. Our GoldSim simulation software package provides the power, flexibility and usability necessary to efficiently simulate and understand the future behavior of complex systems in business, engineering and science.

The goal of the GoldSim Newsletter is to provide information that helps you get the most out of GoldSim. Each newsletter delivers the latest GoldSim news, as well as a number of regular items. This one includes GoldSim news items, a tip 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 old issues.

Since this newsletter is for you, we encourage you to send us your comments and contributions. Send your contributions to newsletter@goldsim.com.

GoldSim International User Conference and Training Workshops Scheduled for October 10-13, 2004 in Las Vegas, Nevada

The Third Annual GoldSim User Conference will be held in Las Vegas, Nevada on Tuesday and Wednesday, October 12 and 13, 2004. This date is rapidly approaching, so if you plan on attending, please sign up now.

Two workshops will be held just prior to the Conference and attendees can attend either workshop at no extra charge. “GoldSim Model Building: Basic Concepts” will be held on October 10th and 11th. Concurrently, on October 11th “Advanced GoldSim Topics” will be held for experienced GoldSim users. This workshop will discuss a number of advanced GoldSim topics, including two new modules now under development (and planned for release this Fall), the Reliability Module, and the Optimization Module.

All training and conference sessions will be held at the Tuscany Suites & Casino, located just blocks from the Las Vegas Strip.

The User Conference will be a terrific opportunity for you to share experiences with other users and the GoldSim developers, and to provide input for the future development of GoldSim. Please consider presenting your GoldSim model(s) to the conference attendees, either through a formal 30-minute presentation or in a poster presentation. This simply requires the submission of a short abstract along with your Registration Form.

GoldSim 8.02 Available for Download

All users are encouraged to download GoldSim version 8.02, which was released on June 25, 2004. Version 8.02 combines a number of previous service packs for 8.01, and adds a number of additional minor modifications and bug fixes. Of particular interest are modifications to improve the speed of reparsing large models, improvements to the Latin Hypercube algorithm, and a large number of minor algorithmic changes to better faciliate simulation of complex environmental systems.

All current members of the GoldSim Subscription Program can download Version 8.02 now from the GoldSim Resource Center (GRC). Once you update the software, don't forget to read the Release Notes to see a complete list of the new features and changes included in Version 8.02.

GoldSim Use Grows Among Regulators Within the Radioactive Waste Management Industry

One of GoldSim's original application areas was radioactive waste management. This is still a major application area for GoldSim, with many users throughout North America, Europe and Asia using GoldSim in this arena. Most of these users are government organizations involved with evaluating the perfomance of proposed or existing radioactive waste management facilities. For example, the US Department of Energy is currently using GoldSim to support its License Application for disposal of the nation's spent nuclear fuel at Yucca Mountain, Nevada.

Most of the existing users in this arena are proponents or operators of the facilities being evaluated. Recently, a number of regulatory agencies around the world have also started to use GoldSim in order to independently evaluate proposed and existing facilities. This includes the Nuclear Regulatory Commission in the US, the Environment Agency of England and Wales in the UK, and the Japan Nuclear Energy Safety Organization (JNES).

With the growing use of GoldSim both by the propenents and regulators of radioactive waste management facilities, GoldSim has become one of the standard tools in this industry.

WHAT'S COOKING

Version 8.1

The GoldSim development team has been hard at work on a significant new version (Version 8.1) since late last year. Due to the extensive nature of some of the changes, it has taken us a bit longer than expected to complete this version. We now anticipate that this version will be available in the Fall of 2004. Version 8.1 will contain some features that we are very excited about, including:

  • Container-Specific and Dynamic Timesteps. This is a powerful new feature that allows different parts of your GoldSim model to use different timesteps and for timesteps to change dynamically during a simulation.

  • Improved Spreadsheet Element Functionality. We are completely rewriting the Spreadsheet element to make it more powerful and easier to use. This will make it much easier to dynamically import and export data between GoldSim and an Excel spreadsheet.

  • Optimization. We are adding an Optimization Module to GoldSim that can be used to optimize (and calibrate) your models.

The Reliability Module

For nearly a year we have been working on a powerful new module that will facilitate simulation of the reliability and performance of complex engineering systems (e.g., vehicles, spacecraft, factories, power plants). This Reliability Module is in beta testing as we continue to document and improve it. We expect to release it concurrently with or soon after the release of Version 8.1.
