<h1>About hypotheses</h1>

<p><img src="../i_blue.jpg" x-maintain-ratio="TRUE" width="30px" height="30px" border="0" class="img_whs1"> <span style="font-weight: bold;"><B>Hypotheses</B></span> 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.
