<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 hypo_quad_params_anchor
|
|
<h2>Quadrangle parameters</h2>
|
|
|
|
<b>Quadrangle parameters</b> is a hypothesis for
|
|
Quadrangle (Mapping), which allows using this algorithm for meshing of
|
|
triangular faces.In this case it is necessary to select the <b>Base vertex</b>
|
|
used as a degenerated edge.

|

\image html hypo_quad_params_res.png "The resulting mesh"
|
|
|
|
This hypothesis can be also used to mesh a segment of a circular face.
|
|
Please, consider that there is a limitation on the selectiion of the degenerated
|
|
vertex for the faces built with the angle > 180 degrees (see the picture).
|
|
|
|
\image html hypo_quad_params_2.png "3/4 of a circular face"
|
|
|
|
In this case, selection of a wrong vertex for the <b>Quadrangle parameters</b>
|
|
hypothesis will generate a wrong mesh. The picture below
|
|
shows the good (left) and the bad (right) results of meshing.
