You display the full parameter name in an Excel Add-In by entering the "ParameterDescription" function.

You can show the engineering units for each parameter used in the Excel Add-In. Paste the function "ParameterUnits" and specify the parameter argument, and the units for that parameter will be displayed

The units displayed for the calculated output values can be set by selecting the Options | Unit Preferences menu item. Each property can be selected from the list, and the preferred units applied by selecting the desired unit from the list, and clicking the Set As Preferred Unit button. The units that appear in the list of available units for the input properties can be controlled by checking or unchecking the box next to each unit listed for a property. The selected units can be set as the user's default, so they are used every time the user starts SteamCalc. Multiple...

To calculate the saturated liquid or vapor properties, select the input property as Property #1. Then select either Saturated Liquid or Saturated Vapor as Property#2.

To calculate properties over a range of values, select the Range tab on the main SteamCalc window. This tab allows you to enter a fixed point for the first property, and a range of values for the second property. The calculated values are displayed in the output grid based on an incremental range value that you specify. The values for a range calculation can be plotted graphically by selecting the Options | Create Graph menu item.

To calculate the properties of two points simultaneously, select the Two Points tab on the main SteamCalc window. This tab allows you to enter the property data for two points. The results for both points will be displayed simultaneously. In addition, the difference between the values calculated at each point is displayed in the output.

Whenever possible, use the Lumped Adiabatic solution method when performing optimization because it is much faster. Final optimization runs can be performed with the default marching method.
