\n Extrusion is used to build mesh elements of plus one \n Extrusion is used to build mesh elements of plus one
dimension than the input ones. Any node, segment or 2D element can be dimension than the input ones. Boundary elements around elements of
extruded. Each type of elements has a corresponding type of extruded elements: plus one dimension are additionally created. All created elements
can be automatically grouped.
<p>Any node, segment or 2D element can be extruded. Each type of
elements is extruded into a corresponding type of result elements:
