About the Simple Example

This example demonstrates a simple Isight model that wraps an Excel worksheet in Isight to create a simple simulation process flow with a single execution. A process component (Loop) is added to provide results from multiple executions of the model.

This example uses an Excel workbook called SpringCalcs.xls, which is included in your Isight installation.

Note: This example uses Excel and, therefore, will work only on Windows. If you are using Linux, proceed to About the Simcode Example.

The following tasks are demonstrated:

  • Creating a new model using the Task component and adding an Excel component

  • Configuring an Excel component (specifying a workbook and mapping parameters using different methods)

  • Executing the model

  • Viewing the results

  • Changing the Task component to a Loop component

  • Configuring a Loop component

  • Re-executing the model

  • Viewing additional results

The problem used for this example is a classical tension-compression spring problem. The wire diameter, d, coil diameter, D, and the number of coils, n, are the design variables. Assuming a 10 lb load on the spring, formulae in the Excel spreadsheet calculate the mass, deflection, shear stress, surge frequency, and size of the spring. For example, a formula in cell H10 calculates the size of the coil by adding the coil diameter to the wire diameter. Output parameters from the Excel component extract data from specified cells of the spreadsheet. For example, the Isight Size parameter is the value of the cell H10.

You run this example using Isight in Standalone mode. In Standalone mode Isight connects to the local library on your computer and does not establish a connection with a SIMULIA Execution Engine. Standalone mode is selected if no SIMULIA Execution Engine connection profiles have been created.
