<p><span style="font-weight: bold;"><B>Start and End Length</B></span> hypothesis
|

allows to divide a geometrical edge into segments so that the first and

the last segments have a specified length. The length of each but the

first segment differs from length of the previous one by a constant factor.
|

Then mesh nodes are constructed at segment ends location and 1D mesh elements

are constructed on them.</p>

There must be one Algorithm and one or several Hypotheses for each dimension

of your object, otherwise you will not get any mesh at all. Of course,

if you wish to mesh a face, which is a 2d object, you don't need to define

<h1>Additional Hypotheses</h1>
|

|

<p><span style="font-weight: bold;"><B>Additional Hypotheses</B></span> can be
|

applied as a supplement to the main hypotheses, introducing additional
|

concepts to mesh creation.</p>
|
||||
|
||||
<p> </p>
|
||||
|
||||
<p>To define an <span style="font-weight: bold;"><B>Additional Hypothesis</B></span>
|
||||
simply select it in <span style="font-weight: bold;"><B>Create Mesh</B></span>
|
||||
menu. These hypotheses are actually changes in the rules of mesh creation
|
||||
and as such don't possess adjustable values. </p>
|
||||
|
||||
<h3>Non Conform mesh allowed hypothesis</h3>
|
||||
|
||||
<p><span style="font-weight: bold;"><B>Non Conform mesh allowed</B></span> hypothesis
|
||||
allows to generate non-conform meshes (that is, meshes having some edges
|
||||
ending on an edge or face of adjacent elements). </p>
|
||||
|
||||
<h3>Quadratic Mesh</h3>
|
||||
|
||||
<p>Quadratic Mesh hypothesis allows to build a quadratic mesh (whose edges
|
||||
are not straight but broken lines and can be defined by three points:
|
||||
first, middle and last) instead of an ordinary one. </p>

|
||||
|
||||
<p><span style="font-weight: bold;"><B>Propagation of 1D Hypothesis on opposite
|
||||
edges </B></span>allows to propagate a hypothesis onto an opposite edge. If
|
||||
a local hypothesis and propagation are defined on an edge of a quadrangular
|
||||
face, the opposite edge will have the same hypothesis, unless another
|
||||
hypothesis has been locally defined on the opposite edge.</p>

<p>For sewing free borders you should define three points on each border:

first, second and the last node: </p>

|

<ul type="disc" class="whs2">

(as far as the free border usually forms a closed contour);</p></li>
|
||||
|
||||
<li class=kadov-p><p> the

last node specifies the end of the border.</p></li>
|

</ul>
|
||||
|
||||
<p> </p>
|
||||
|
||||
<p>You can select these nodes in the 3D viewer or define by its id.</p>
|
||||
|
||||
<p> </p>
|
||||
|
||||
<p>The first and the second nodes should belong to the same link of a face.
|
||||
The second and the last nodes of a border can be the same. The first and
|
||||
the last nodes of two borders can be the same. The corresponding end nodes
|
||||
of two borders will be merged. Intermediate nodes of two borders will
|
||||
be either merged or inserted into faces of the opposite border.</p>
|
||||
|
||||
<p> </p>
|
||||
|
||||
<p>The sewing algorithm is as follows:</p>
|
||||
|
||||
<p> </p>
|
||||
|
||||
<p class="whs4">1. The parameter (U) of each node within
|
||||
a border is computed. So that the first node has U=0.0, the last node
|
||||
has U=1.0, for the rest nodes 0.0 < U < 1.0;</p>
|
||||
|
||||
<p class="whs4">2. Compare node parameters of the two borders.
|
||||
If two nodes of the opposite borders have close parameters, they are merged,
|
||||
i.e. a node of the first border is replaced in all elements by a node
|
||||
of the second border. If a node has no node with a close parameter in
|
||||
the opposite border, it is inserted into an edge of element of the opposite
|
||||
border, an element is split. Two nodes are considered close enough to
|
||||
merge, if difference of their parameters is less than one fifth of minimum
|
||||
length of adjacent face edges on the borders.</p>

<p> </p>

<p>The borders of meshes for sewing are defined as for "Sew free borders"

<p>The algorithm is following: counting nodes starting at the first ones,

the n-th node of the first border is merged with the n-th node of the

<p>"Sew border to side" is intended to sew a free border to a
|
||||
mesh surface.</p>
|
||||
|
||||
<p>The free border is defined as for "Sewing of free borders".
|
||||
The place where to sew the border is defined by two nodes, between which
|
||||
the border faces are placed, so that the first border node is merged with
|
||||
the first node on the side and the last node of the border is merged with
|
||||
the second specified node on the side.</p>

|
||||
<p> </p>
|

|
||||
<p class="whs4"> </p>
|
||||
|
||||
<p>The algorithm is following.</p>
|
||||
|
||||
<p>1. Find a sequence of linked nodes on the side such that the found links
|
||||
to be most co-directed with the links of the free border.</p>
|
||||
|
||||
<p>2. Sew two sequences of nodes using algorithm of "Sewing of free
|
||||
berders".</p>
|
||||
|
||||
<p>For sewing border to side you should define three points on the border
|
||||
and two points on the side. User can select these nodes in 3D viewer or
|
||||
define node by its id.</p>

<p>Two corresponding nodes on each side must be specified. They must belong

|
||||
that a face is not planar and is applied only to 2D elements with 4 nodes.
|
||||
This quality control criterion is based on a projection plane created
|
||||
by:</p>
|
||||
|
||||
<p class="whs2">1. bisecting the four element edges, </p>
|
||||
|
||||
<p class="whs2">2. creating a point on the plane at the vector
|
||||
average of the corners, where the x-axis extends from the point to the
|
||||
bisector on edge 2. </p>
|
||||
|
||||
<p class="whs3">The plane normal is in the direction of the
|
||||
cross product of the x-axis and the vector from the origin to the bisector
|
||||
of edge 3. Every corner of the quad will then be a distance “h” from the
|
||||
plane. The length of each half edge is measured and the shortest length
|
||||
is assigned “l”. The warp angle is the arcsine of the ratio of the projection
|
||||
height “h” to the half edge length “l”. </p>
