122 boundary conditions which will be taken into account at calculations of

123 meshes or submeshes basing on geometrical objects. These hypotheses allow
\r
124 you to manage the level of detail of the resulting meshes or submeshes:
\r
125 when applying different hypotheses with different parameters you can preset
\r
126 the quantity of meshing elements which will compose your mesh. So, it
\r
127 will be possible to generate a rough or a more refined mesh or submesh.
