\page about_hypo_page About Hypotheses
|
|
|
|
\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-mesh".
|
|
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. From the context menu of the
|
|
hypothesis you can invoke a dialog for modification of its parameters,
|
|
and \b Unassign command that will unassign the hypothesis from all
|
|
the meshes and sub-meshes using it.
|
|
Modification of any hypothesis parameter and unassignment of a
|
|
hypothesis leads to automatic removal of elements generated with use
|
|
of this hypothesis.
|
|
|
|
