About Evaluation Groups

An evaluation group is analogous to a plot group: It has zero or more numerical evaluation nodes (all applicable evaluation nodes that are also available under ) as subnodes. The node contains common settings and also acts as the table to which its subnodes evaluate. The values in an evaluation group’s table can be reevaluated automatically when solving (see Update of Results). For information about the available evaluation nodes, see Derived Value Types. For information about the evaluation group tables, see The Table Window and Tables Node. To add an node (

), right-click the main node and select . Then right-click the node to add the evaluation nodes to be evaluated within that evaluation group. You can evaluate all nodes under an node by right-clicking it.

The node’s window contains the following sections:

In this section you define the data to use for the evaluations. See Common Results Node Settings for more information.

You can also store the evaluation group’s table data on the file system instead of, or in addition to, storing it in the model. Select a way to store the table data from the list:

For the storage in the model, specify the buffer size in the field. The default for new evaluation group tables is taken from the page in the dialog box (factory setting: 10,000 rows). If the table size exceeds that number of rows, the software removes rows from the top. If you use a large number, most table data will fit in the table without being truncated.

	The row limit applies to table data in the model only and not to tables with data stored in a file.

In this section, use the list to control which parameters value columns to include in the evaluation group’s table: Use (the default) to include the parameter value columns are included for the first active evaluation subnode, which is a good choice if all evaluation subnodes have the same parameter value columns. Otherwise, use to include all parameter value columns, or use to include no parameter value columns.
