Select the top and bottom nodes or edges of the 2D element and define the mesh size by entering the mesh size directly or the number of divisions between edges or nodes. The number of top nodes and bottom elements must be the same when using a 1D element and if a line (edge) is used, the input seed information for the top and bottom lines (edges) need to be the same. The bottom element, or start point of a line and top element, or start point of a line correspond in order and generate a 2D element. If the start point of the bottom element and end point of the top element correspond such that the element is twisted, use the [Reverse Ends] option to reverse the corresponding order.

The shape of the 2D element can be selected from a triangle or a quadrilateral in advanced options ( ).
