The Elements Menu includes the following commands:
| Command | Description |
|---|---|
| Options | General command – set up the default element options. |
| Select Thin Triangles | General command – selects all thin triangular element that meet the definition specified in the options command. |
| Find | General command – finds the element with a specified ID or location. |
| Assign Material Type | General command – requires a selected element. Sets the material type of the selected elements based on the option defined in the options command. |
| Merge Triangles | Conversion command – merges triangle pairs that meet the standard for rectangles defined in the options command. Can operate on selected elements. |
| Split Quadrilaterals | Conversion command – splits quadrilateral elements into two triangular elements. Can operate on selected elements. |
| QUAD8 ↔ QUAD9 | Conversion command – converts all QUAD8 to QUAD9 elements and vice versa. Only applies to the FESWMS model. Can operate on selected elements. |
| Linear ↔ Quadratic | Conversion command – converts all elements from linear to quad or vice versa. Only applies to TABS and FESWMS models. |
| Triangulate | Generation command – triangulates the selected nodes to form triangle elements. |
| Optimize Triangulation | Generation command – swaps edges of triangular elements to meet the Dulanay criterion. |
