GoldSim 10.5 Released!
GoldSim Technology Group released a new major version of GoldSim, GoldSim 10.5 on December 21, 2010. This version includes a significant number of new features and user interface improvements.
A major new feature, the Script Element has been added. Iterative calculations, complex array manipulations, and other highly customized calculations, many of which could only have been previously done using an External (DLL) element, can now be built directly into GoldSim as a procedural Script without any external programming.
GoldSim 10.5 includes another new element, the Aquifer Pathway for the CT/RT Module. An Aquifer pathway combines the features of a Cell and a Pipe element, and provides a way to simulate processes such as vertical transport through an unsaturated (vadose) zone, and horizontal transport in aquifers, rivers, channels and pipelines.
Date/time simulations can now extend over a much broader range: 1 January 1700 to 31 December 9999. GoldSim 10.5 also includes other enhancements for plotting time history results involving dates.
When editing an input field, GoldSim automatically suggests the names of existing outputs at the bottom of the input field.
GoldSim 10.5 supports the extended worksheet ranges (1,048,576 rows by 16,384 columns) introduced in Excel 2007.
If statements can handle mixtures of arrays and scalars.
The Time Series elements now include a new representation: Changes and constant values over the previous interval. These options make it easier to import measured time series data, as that is the manner in which it is often actually recorded (i.e., a change or an average value over the previous time interval).
The GoldSim Units Manager has been redesigned.
Lookup Tables now support an option to be linked to a text file. The text file data is imported automatically whenever the data in the file is modified.
GoldSim 10.5 provides powerful tools for both exploring and manually changing the causality sequence.
There are also many less visible changes and a number of bug fixes included in GoldSim 10.5. A description of the important changes can be found in the Summary Document.
All current members of the GoldSim Subscription Program can download the GoldSim 10.5 installation file from the Download section of our website.
Join Us in Upcoming GoldSim Webinars
Introduction to GoldSim 10.5
We invite you to an Introduction to GoldSim Version 10.5 webinar on 20 January, 2010 at 8AM and 4PM PST(-8 hours GMT). We will discuss the major new features in GoldSim 10.5. This webinar will give you a quick overview and discuss their potential applications so that you can start taking advantages of these new features.

Webinars for Water and Environmental Engineers and Planners
We are planning on having a series of webinars for water and environmental engineers and planners, once a month starting in January.
The fist webinar, held in January 27th, 2011 at 8AM and 4PM PST(-8 hours GMT), will introduce scripting inside a GoldSim model using a pumping head calculation example. In the example, the flow rate and the total dynamic head are calculated simultaneously using a bisection solver in a Script element. The pumped flow rate is based on the manufacturer's pump performance curve.
You may take a look at a list of upcoming Webinars. To register, please fill out and submit a webinars registration form.

Examples of GoldSim's New Script Element
GoldSim’s new Script element provides a user friendly alternative to programming DLLs for highly customized calculations, such as iterative loops and working with arrays. This article introduces the Script element and goes through the Script element examples that are distributed with GoldSim 10.5, including an example of iterative calculations (Newton’s method) and an example of working with matrices to calculate a correlation matrix. The end of the article links you to two new models in the Model Library that use the Script element in water resources applications.
