Time History Function Definition - from File

Use the Time History Function Definition form to define a time history function based on a text file of time history function data.

The program reads the time history function file as follows:

Typically, the program does not import the file into its database. It simply maintains a link to the file location. Thus, if either the time history function file or the .bdb file is moved to another location, the program may be unable to locate the function file. If the Convert to User Defined button is clicked, the program imports the time history into its database file, making the data always available to the model.

Important:  Do not click the Convert to User Defined button until all information has been specified in the Function File, Values are and Format Type areas.

Access the Time History Function Definition form to define a time history function based on a selected file as follows:

 

Click the Loads > Functions Type > Time History > Expand arrow command, or on the Bridge Wizard select the Time History Functions item and click the Define/Show Tree Hist. Funcs. button, to display the Define Time History Functions form. Then do one of the following:

    • Select Function from File from the Choose Function Type to Add drop-down list and click the Add New Function button.

    • Select a previously defined function and click the Modify/Show Function button.

Alternatively, click the Loads > Functions Type > Time History > New command and select Cosine from the resulting form.
