The Method Control provides meshing algorithms used for meshing solid and sheet bodies. The Method control is valid only for a body. When you do not select any Method Control, application applies Automatic Method on all bodies to provide a successful automated mesh. By default, the application attempts to use hexahedral elements for solid bodies and quadrilateral element generation for sheet bodies. If a solid body is not sweepable, the body is meshed with the Patch Conforming Tetrahedrons mesher.

To set the values for the Method control,

On the Tree Outline, right-click Mesh and click Insert > Method.

Or

On the Tree Outline, click Mesh and click Method in the Mesh Context tab on the Ribbon.
