  <h4>Syntax</h4>
  <blockquote>
  <pre><b>Connections.rooted</b>(x)</pre>
  </blockquote>
  <h4>Description</h4>
  <p>The operator \"rooted\" was introduced to improve efficiency:
  A tool that constructs the graph with the Connections.branch/.root etc.
  built-in operators has to cut the graph in order to arrive at \"spanning trees\".
  If there is a statement \"Connections.branch(A,B)\", then \"rooted(A)\" returns true,
  if \"A\" is closer to the root of the spanning tree as \"B\". Otherwise false is returned.
  For the MultiBody library this allows to avoid unnecessary small linear systems of equations.
  </p>
  <h4>Known Bugs</h4>
  <p>
  OpenModelica, <b>rooted</b>(x) always returns true.
  See <a href=\"https://trac.modelica.org/Modelica/ticket/95\">rooted ticket in the Modelica Trac</a> for details.

Loads a Modelica library.
<h4>Syntax</h4>
<blockquote>
<pre><b>loadModel</b>(Modelica)</pre>
<pre><b>loadModel</b>(Modelica,{\"3.2\"})</pre>
</blockquote>
<h4>Description</h4>
<p>loadModel() begins by parsing the <a href=\"modelica://OpenModelica.Scripting.getModelicaPath\">getModelicaPath()</a>, and looking for candidate packages to load in the given paths (separated by : or ; depending on OS).</p>
<p>The candidate is selected by choosing the one with the highest priority, chosen by looking through the <i>priorityVersion</i> argument to the function.
If the version searched for is \"default\", the following special priority is used: no version name > highest main release > highest pre-release > lexical sort of others (see table below for examples).
If none of the searched versions exist, false is returned and an error is added to the buffer.</p>
<p>A top-level package may either be defined in a file (\"Modelica 3.2.mo\") or directory (\"Modelica 3.2/package.mo\")</p>
<p>The encoding of any Modelica file in the package is assumed to be UTF-8.
Legacy code may contain files in a different encoding.
In order to handle this, add a file package.encoding at the top-level of the package, containing a single line with the name of the encoding in it.
If your package contains files with mixed encodings and your system iconv supports UTF-8//IGNORE, you can ignore the bad characters in some of the files.
You are recommended to convert your files to UTF-8 without byte-order mark.
</p>

<table summary=\"Modelica version numbering\">
<tr><th>Priority</th><th>Example</th></tr>
<tr><td>No version name</td><td>Modelica</td></tr>
<tr><td>Main release</td><td>Modelica 3.3</td></tr>
<tr><td>Pre-release</td><td>Modelica 3.3 Beta 1</td></tr>
<tr><td>Non-ordered</td><td>Modelica Trunk</td></tr>

<h2>Usage</h2>
<p>Modelica3D requires some changes to the standard ModelicaServices in order to work correctly. These changes will make your MultiBody models unable to simulate because they need an object declared as:</p>
<pre>inner ModelicaServices.Modelica3D.Controller m3d_control</pre>
<p>Example session:</p>
<pre>loadModelica3D();getErrorString();
loadString(\"model DoublePendulum
  extends Modelica.Mechanics.MultiBody.Examples.Elementary.DoublePendulum;
  inner ModelicaServices.Modelica3D.Controller m3d_control;
end DoublePendulum;\");getErrorString();
system(\"python \" + getInstallationDirectoryPath() + \"/lib/omlibrary-modelica3d/osg-gtk/dbus-server.py &amp;\");getErrorString();
simulate(DoublePendulum);getErrorString();</pre>
<p>This API call will load the modified ModelicaServices 3.2.1 so Modelica3D runs. You can also simply call loadModel(ModelicaServices,{\"3.2.1 modelica3d\"});</p>
<p>You will also need to start an m3d backend to render the results. We hid them in $OPENMODELICAHOME/lib/omlibrary-modelica3d/osg-gtk/dbus-server.py (or blender2.59).</p>
