\n Each <b>Entity type</b> has its specific list of criteria, however all
filters have common syntax. For each criterion you should specify the
<b>Threshold Value</b> and whether we search for the elements that should be
\b More, \b Less or \b Equal to this \b Value. You should also specify if the
criterion is \b Unary or \b Binary.
\b More, \b Less or \b Equal to this \b Value. You can also nagate the

specify logical relations between criteria using \b Binary operators
Or and And.

Some criteria are applicable to all <b>Entity types</b>:
<ul><li>
<b>Belong to Geom</b> selects entities whose all nodes belong to a
submesh on the shape defined by <b>Threshold Value</b>. The threshold shape
must be sub-shape of the main shape of mesh.
</li><li>
<b>Lying on Geom</b> selects entities whose at least one node belongs to a
submesh on the shape defined by <b>Threshold Value</b>. The threshold shape
must be sub-shape of the main shape of mesh.
</li><li>
<b>Range of IDs</b> allows selection of entities having certain
IDs. <b>Threshold Value</b> can be like this: "1,2,3,50-60,63,67,70-78"
</li>
</ul>
The following criteria are applicable to all <b>Entity types</b> except <b>Volumes</b>:
<ul><li>
<b>Belong to Plane</b> selects entities whose all nodes belong to a
specified plane within a given <b>Tolerance</b>.
</li><li>
<b>Belong to Cylinder</b> selects entities whose all nodes belong to a
specified cylinder within a given <b>Tolerance</b>.
</li><li>
<b>Belong to Surface</b> selects entities whose all nodes belong to a
specified arbitrary surface within a given <b>Tolerance</b>.
</li>
</ul>
Additional criteria to select mesh <b>Edges</b> are the following:
<ul><li>
<b>Free Borders</b> selects free 1D mesh elements, i.e. edges belonging to
one face only. See also a
\ref free_borders_page "Free Borders quality control".
</li><li>
<b>Borders at Multi-Connections</b> selects edges belonging to several faces.
The number of faces should be more, less or equal (within a given <b>Tolerance</b>)
to the predefined <b>Threshold Value</b>. See also a
\ref borders_at_multi_connection_page "Borders at Multi-Connection quality control".
</li><li>
<b>Length</b> selects edges with a value of length, which is more, less or equal
(within a given <b>Tolerance</b>) to the predefined <b>Threshold Value</b>.
See also a
\ref length_page "Length quality control".
</li>
</ul>
Additional criteria to select mesh <b>Faces</b> are the following:
<ul><li>
<b>Aspect ratio</b> selects 2D mesh elements with an aspect ratio (see also an
\ref aspect_ratio_page "Aspect Ratio quality control"), which is more, less or equal
(within a given <b>Tolerance</b>) to the predefined <b>Threshold Value</b>.
</li><li>
<b>Warping</b> selects quadrangles with warping angle (see also a
\ref warping_page "Warping quality control"), which is more, less or equal
(within a given <b>Tolerance</b>) to the predefined <b>Threshold Value</b>.
</li><li>
<b>Minimum angle</b> selects triangles and quadrangles with minimum angle (see also a
\ref minimum_angle_page "Minimum angle quality control"), which is more, less or equal
(within a given <b>Tolerance</b>) to the predefined <b>Threshold Value</b>.

<b>Taper</b> selects quadrangles cells with taper value (see also a
\ref taper_page "Taper quality control"), which is more, less or equal (within a given
<b>Tolerance</b>) to the predefined <b>Threshold Value</b>.

<b>Skew</b> selects triangles and quadrangles with skew value (see also a
\ref skew_page "Skew quality control"), which is more, less or equal (within a given

\ref area_page "Area quality control"), which is more, less or equal (within a given
<b>Tolerance</b>) to the predefined <b>Threshold Value</b>.
</li><li>
<b>Free edges</b> selects 2D mesh elements consisting of edges belonging to
one element of mesh only. See also a
\ref free_edges_page "Free Edges quality control".
</li><li>
<b>Borders at Multi-Connections 2D</b> selects cells consisting of edges belonging to
several elements of mesh. The number of mesh elements should be more, less or equal
