4.2.4. Element Topology

The element topology property data form is a generation and editing tool for Aqwa elements. All elements within a loaded model can be viewed and edited from within this form. You may also create a new element data set (no pre-loaded model required).


Note:  Each structure must have its own element topology data set.


The form allows you to edit element topology property data for multiple structures using either the element generation button and/or by directly editing the element data within the element group table.

Four panels appear on the form:


Note:  Refer to the Aqwa Reference Manual for limits on the maximum permissible numbers of diffracting and total elements.
