Graphical User Interface Examples in GoldSim

Posted by Jason Lillywhite

I've updated many of our dashboard examples to include the new embedded chart feature available in GoldSim 12.1. Many of these have been updated since my last blog post showing example dashboards. Below are screen captures showing some of these along with links to read more about them and even download the models so you can try them out yourself.

PID Controller in GoldSim

Posted by 

The proportional-integral-derivative (PID) controller is a useful feedback control mechanism commonly used in industrial applications such as furnace temperature control, pH neutralization, and flow control. These systems commonly require that their state be monitored continuously and controls adjusted based on error from a setpoint or target. As seen in the schematic below, the controller makes a change to a process then a sensor is used to provide feedback to the input of the controller.

This type of control can also be used for controlling inflows and/or outflows from a storage facility like a lake or water tank. This blog post describes the application of the PID controller in 2 different GoldSim models: a detailed process flow model with a cylindrical tank and an environmental system with a large water supply reservoir. This logic is found to work well in both cases even though they .

GoldSim 12.1 is Released!

Posted by 
We are excited to announce that GoldSim 12.1 is now available.

In addition to a number of other changes, GoldSim 12.1 includes the following new features:

  •  Embedded dashboard charts and tables: You can embed a result window (as either a chart or a table) directly into a Dashboard. 
  • Real-Time updating of result displays: Time History results are updated continuously (each timestep or each realization) during the simulation. 
  • Exporting time history probability statistics to a spreadsheet: Export multiple statistics from Probability History results.
  • Model inventory: Generate a simple XML file that can be viewed in a text editor, browser or XML editor that echoes out all of the elements in a GoldSim model. 
All of the new features in GoldSim 12.1 are described in detail in the GoldSim 12.1 Summary Document.

In addition to an updated Help system to describe all the new features, updated user manuals are installed with the software (in PDF format). Bound manuals can also be ordered directly from Amazon.com (and this is likely to be less expensive than printing and binding them yourself).

You can download GoldSim 12.1 directly from the GoldSim website. In order to use GoldSim 12.1, you must enter a new Activation ID. All users with current Maintenance should have received a new ID.
