<h2>Max Element Area</h2>
|
|
|
|
<b>Max Element Area</b> hypothesis is applied for meshing of 2D faces
|
|
composing your geometrical object. Definition of this hypothesis
|
|
consists of setting the <b>maximum area</b> of meshing elements (depending on
|
|
the chosen meshing algorithm it can be <b>triangles</b> or <b>quadrangles</b>),
|
|
which will compose the mesh of these 2D faces.

operation.

\anchor length_from_edges_anchor
|
|
<h2>Length from Edges</h2>
|
|
|
|
<b>Length from edges</b> hypothesis builds 2D mesh segments having a
|
|
length calculated as an average edge length for a given wire.
|
|
|
|
<b>See Also</b> a sample TUI Script of a
|
|
\ref tui_length_from_edges "Length from Edges" hypothesis operation.

\anchor quadrangle_preference_anchor
|
|
<h2>Quadrangle Preference</h2>
|
|
|
|
This algorithm can be used only together with Quadrangle (Mapping)
|
|
algorithm. It allows to build quadrangular meshes even if the number
|
|
of nodes at the opposite edges of a meshed face is not equal,
|
|
otherwise this mesh will contain some triangular elements.
|
|
<br>
|
|
This hypothesis has one restriction on its work: the total quantity of
|
|
segments on all four sides of the face must be even (divisible by 2).

\anchor triangle_preference_anchor
|
|
<h2>Triangle Preference</h2>
|
|
|
|
This algorithm can be used only together with Quadrangle (Mapping)
|
|
algorithm. It allows to build triangular mesh faces in the refinement
|
|
area if the number of nodes at the opposite edges of a meshed face is not equal,
|
|
otherwise refinement area will contain some quadrangular elements.
