\b Hypotheses represent boundary conditions which will be taken into
account by meshing algorithms.
The hypotheses allow you to manage the level of detail of
the resulting mesh: 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.
The choice of a hypothesis depends on the selected algorithm.
Hypotheses are created during creation and edition of
\ref constructing_meshes_page "meshes" and

\ref constructing_submeshes_page "sub-meshes".
Once created a hypotheses can be reused during creation and edition of
other meshes and sub-meshes. All created hypotheses and algorithms are
present in the Object Browser in \a Hypotheses and \a Algorithms
folders correspondingly. It is possible to open a dialog to modify the
parameters of a hypothesis from its context menu. This menu also
provides \b Unassign command that will unassign the hypothesis from
all meshes and sub-meshes using it. Modification of any parameter of a
hypothesis and its unassignment leads to automatic removal of elements
generated using it.
