\page building_compounds_page Building Compound Meshes
\n Compound Mesh is a combination of several meshes. All elements and
groups present in input meshes are present in the compound
mesh. However, it does not use geometry or hypotheses of the initial meshes.
The links between the input meshes and the compound mesh are not
supported, consequently the modification of an input mesh does not lead to
the update of the compound mesh.
<em>To Build a compound mesh:</em>
\par
From the \b Mesh menu select <b>Build Compound</b> or click <em>"Build
Compound Mesh"</em> button in the toolbar.

<center><em>"Build Compound Mesh" button</em></center>
\par
The following dialog box will appear:

\par
<ul>
<li>\b Name - allows selecting the name of the resulting \b Compound mesh.</li>
<li><b>Meshes, sub-meshes, groups</b> - allows selecting the meshes,
sub-meshes and groups to be concatenated. They can be
chosen in the Object Browser while holding \b Ctrl button.</li>
<li><b>Processing identical groups</b> - allows selecting the method
of processing the namesake groups existing in the input meshes.
They can be either <ul>
<li>\b United - all elements of \em Group1 of \em Mesh_1 and \em
Group1 of \em Mesh_2 become the elements of \em Group1 of the
\em Compound_Mesh, or</li>
<li>\b Renamed - \em Group1 of \em Mesh_1 becomes \em Group1_1
and \em Group1 of \em Mesh_2 becomes \em Group1_2.</li>
</ul>
See \ref grouping_elements_page "Creating Groups" for more information
about groups.</li>
<li><b>Create groups from input objects</b> check-box permits to
automatically create groups corresponding to every initial mesh.

<li>You can choose to additionally
\ref merging_nodes_page "Merge coincident nodes"
\ref merging_elements_page "and elements" in the compound mesh, in
which case it is possible to define the \b Tolerance for this
operation.</li>
</ul>
