ANSYS 15.0: Element Selection Options

The release of ANSYS Mechanical (Workbench) 15.0 offers new element selection options.

Selections can be accomplished via picking in the graphics window, or through creation of elemental named selections. For elemental named selections, in addition to direct graphical selection, a variety of criteria can be applied in order to generate the selection, including location, element volume/area, mesh metric, other named selections, and even conversion to/from nodal selections (NSLE, ESLN). After generation, elemental named selections can be exported to text or Excel files through a right-mouse-click. All selections are also written to the ds.dat file after solving as components.

For graphics window selections, element information including element ID, element type, and node ID is immediately displayed in the Selection Information window (ELIST functionality).

There are also several different viewing options for the new element selections, achieved by toggling Wireframe mode and Show Mesh mode on and off.

Following are examples of several of these new element selection options.
