\page about_hypo_page About Hypotheses
\n \b Hypotheses represent boundary conditions which will be taken into
account at calculations of meshes or submeshes basing on geometrical
objects. These hypotheses allow you to manage the level of detail of
the resulting meshes or submeshes: when applying different hypotheses
with different parameters you can preset the quantity of meshing
elements which will compose your mesh. So, it will be possible to
generate a rough or a more refined mesh or submesh.
In \b MESH there are the following Basic Hypotheses (to introduce
them, you operate numerical values):
<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 geometrical object (shape) which will be meshed</li>
<li>the algorithm, which will be selected for meshing of this geometrical object (shape)</li>
</ul>
