\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 "Average 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 quadrangle_preference_anchor "Quadrangle Preference"</li>
|
|
<li>\ref triangle_preference_anchor "Triangle Preference"</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>
|
|
|
|
Some hypotheses are strictly combined with plug-in
|
|
meshers and thus, work only with definite algorithms.
|
|
<ul>
|
|
<li>\subpage netgen_2d_3d_hypo_page</li> - work with NetGen algorithm.
|
|
<li>\subpage ghs3d_hypo_page</li> - works with GHS3D algorithm.
|
|
<li>\subpage ghs3dprl_hypo_page</li> - works with GHS3DPRL (tepal) algorithm.
|
|
<li>\subpage blsurf_hypo_page</li> - works with BLSURF algorithm.
|
|
</ul>
|
|
|
|
There also exist
|
|
\subpage additional_hypo_page "Additional Hypotheses" used together
|
|
with other hypotheses:
|
|
<ul>
|
|
<li>Propagation of 1D Hypothesis on opposite edges</li>
|
|
<li>Non conform mesh allowed</li>
|
|
<li>Quadratic mesh</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>
