<h1>Extrusion</h1>
|
||
|
|
|
||
|
|
<p>Extrusion is a type of surface meshing by generation from discretized
|
||
|
|
lines. It is used to build mesh elements of plus one dimension than the
|
||
|
|
swept ones. Each swept 1D element produces one or more quadrangles (or
|
||
|
|
triangles if one node of a rotated element lays on the revolution axis).</p>
