\page about_hypo_page About Hypotheses

\b Hypotheses represent boundary conditions which will be taken into
account at calculations of meshes or sub-meshes basing on geometrical
objects. These hypotheses allow you to manage the level of detail of
the resulting meshes or sub-meshes: when applying different hypotheses
with different parameters you can preset the quantity or size of
elements which will compose your mesh. So, it will be possible to
generate a coarse or a more refined mesh or sub-mesh.

In \b MESH there are the following Basic Hypotheses:
<ul>
<li>\subpage a1d_meshing_hypo_page "1D Hypotheses" (for meshing of 
<b>edges</b>):</li>
<ul>
<li>\ref arithmetic_1d_anchor "Arithmetic 1D"</li>
<li>\ref average_length_anchor "Local Length"</li>
<li>\ref max_length_anchor "Max Size"</li>
<li>\ref deflection_1d_anchor "Deflection 1D"</li>
<li>\ref number_of_segments_anchor "Number of segments"</li>
<li>\ref start_and_end_length_anchor "Start and end length"</li>
<li>\ref automatic_length_anchor "Automatic Length"</li>
</ul>
<li>\subpage a2d_meshing_hypo_page "2D Hypotheses" (for meshing of <b>faces</b>):</li>
<ul>
<li>\ref max_element_area_anchor "Max Element Area"</li>
<li>\ref length_from_edges_anchor "Length from Edges"</li>
<li>\ref hypo_quad_params_anchor "Quadrangle Parameters"</li>
</ul>
<li>3D Hypothesis (for meshing of <b>volumes</b>):</li>
<ul>
<li>\subpage max_element_volume_hypo_page "Max Element Volume"</li>
</ul>
</ul>

There also exist  
\subpage additional_hypo_page "Additional Hypotheses" used together
with other hypotheses:
<ul>
<li>\ref propagation_anchor "Propagation of 1D Hypothesis on opposite edges"</li>
<li>\ref viscous_layers_anchor "Viscous layers"</li>
<li>\ref quadratic_mesh_anchor "Quadratic mesh"</li>
<li>\ref non_conform_allowed_anchor "Non conform mesh allowed"</li>
<li>\ref quadrangle_preference_anchor "Quadrangle preference"</li>
</ul>

The choice of a hypothesis depends on:
<ul>
<li>the algorithm, which will be selected for meshing of this geometrical object (shape)</li>
<li>the geometrical object (shape) which will be meshed</li>
</ul>
