Errors  

This topic provides details for various messages produced by the software including each of the error conditions that may block the Action : Search, Seek, Trade and Catalog functions.

Invalid Value messages

Each Independent Variable, Dependent Variable and numeric Calculation Input has a predefined range (validmin to validmax) for which it is considered to be valid. If a variable has a value outside this range, it is said to be "invalid". Just as Search will work to stay within constraint boundaries, it will work to keep each variable within its valid range.

Most commonly, negative values for quantities like diameters are considered to be invalid.

The Alerts facility will identify variables that have values outside their valid range. Press the Alerts button to see a list of active alerts. Any variables with values outside their valid range will be identified as "INVALID VALUE". Independent Variables can be modified directly and are sorted to the top of the list. As Dependent Variables cannot be modified directly, they are classified with "Info" severity and sorted to the bottom of the list. Select the entry in the "Value" column to modify the associated variable's value or the value of its constraints.

Search Errors

Conditions that block the operation of Search include:

Follow the link above that corresponds to the message blocking Search.

Invalid Values

While usually a situation of having started with invalid values, it is possible for Search to return a design that contains invalid values. The Help links provided in the Alerts panel may provide specific recommendations to help clear the condition. In some cases it may be necessary to identify which input(s) are responsible for the invalid values and then manually adjust the value of those inputs so as to clear the invalid condition.

Use the AutoSave feature to recover a design as it existed before a Search.
