Define the mesh size directly or input the number of divisions for the area forming edge to set the mesh size.
If the closed domain is within another closed domain, use the [Mesh Inner Domain] option to divide the domain and auto-generate. If an interior line (edge) or point is selected, the option identifies the position of the line or point and creates a node. In particular, the [Include Interior Edges] option can extract sub-shapes from an edge and is a vital option when generating a structural element.

Select lines that form a closed area to generate a mesh in that domain. It does not create a surface for a complex 2D shape and is used to generate a mesh in all areas.
