From the <a href="https://mathworks.com/products/simulink/projects.html">Simulink project</a> mathworks page:
</p>
<blockquote>
<p>
Simulink® and Simulink Projects provide a collaborative, scalable environment that enables teams to manage their files and data in one place.
</p>
<p>
With Simulink Projects, you can:
</p>
<ul class="org-ul">
<li><b>Collaborate</b>: Enforce companywide standards such as company tools, libraries, and standard startup and shutdown scripts. Share your work with rich sharing options including MATLAB® toolboxes, email, and archives.</li>
<li><b>Automate</b>: Set up your project environment correctly every time by automating steps such as loading the data, managing the path, and opening the models.</li>
<li><b>Integrate with source control</b>: Enable easy integration with source control and configuration management tools.</li>
</ul>
</blockquote>
<p>
The project can be opened using the <code>simulinkproject</code> function:
</p>
<div class="org-src-container">
<pre class="src src-matlab">simulinkproject<span class="org-rainbow-delimiters-depth-1">(</span><span class="org-string">'./'</span><span class="org-rainbow-delimiters-depth-1">)</span>;
</pre>
</div>
<p>
When the project opens, a startup script is ran.
The startup script is defined below and is exported to the <code>project_startup.m</code> script.
</p>
<div class="org-src-container">
<pre class="src src-matlab">freqs = logspace<span class="org-rainbow-delimiters-depth-1">(</span><span class="org-type">-</span><span class="org-highlight-numbers-number">1</span>, <span class="org-highlight-numbers-number">3</span>, <span class="org-highlight-numbers-number">1000</span><span class="org-rainbow-delimiters-depth-1">)</span>;

</pre>
</div>
<p>
When the project closes, it runs the <code>project_shutdown.m</code> script defined below.
</p>
<div class="org-src-container">
<pre class="src src-matlab">Simulink.fileGenControl<span class="org-rainbow-delimiters-depth-1">(</span><span class="org-string">'reset'</span><span class="org-rainbow-delimiters-depth-1">)</span>;
</pre>
</div>
<p>
The project also permits to automatically add defined folder to the path when the project is opened.

A <a href="https://.mathworks.com/products/simscape.html">simscape</a> model permits to model multi-physics systems.
</p>
<p>
<a href="https://mathworks.com/products/simmechanics.html">Simscape Multibody</a> permits to model multibody systems using blocks representing bodies, joints, constraints, force elements, and sensors.

<h3 id="org8456f59"><span class="section-number-3">2.1</span> Solid bodies</h3>
<div class="outline-text-3" id="text-2-1">
<p>
Each solid body is represented by a <a href="https://mathworks.com/help/physmod/sm/ref/solid.html">solid block</a>.
The geometry of the solid body can be imported using a <code>step</code> file. The properties of the solid body such as its mass, center of mass and moment of inertia can be derived from its density and its geometry as defined by the <code>step</code> file. They also can be set by hand.

<h3 id="orge3189c0"><span class="section-number-3">2.2</span> Frames</h3>
<div class="outline-text-3" id="text-2-2">
<p>
Frames are very important in simscape multibody, they defined where the forces are applied, where the joints are located and where the measurements are made.
</p>
<p>
They can be defined from the solid body geometry, or using the <a href="https://mathworks.com/help/physmod/sm/ref/rigidtransform.html">rigid transform block</a>.

Solid Bodies are connected with joints (between frames of the two solid bodies).

There are various types of joints that are all described <a href="https://mathworks.com/help/physmod/sm/ug/joints.html">here</a>.

<p>
For each of the joint primitive, we can specify the dynamical properties:
</p>
<ul class="org-ul">
<li>The <b>spring stiffness</b>: either linear or rotational one</li>
<li>The <b>damping coefficient</b></li>
</ul>
<p>
For the actuation, we can either specify the motion or the force:
</p>
<ul class="org-ul">
<li>the force applied in the corresponding DOF is provided by the input</li>
<li>the motion is provided by the input</li>
</ul>
<p>
A sensor can be added to measure either the position, velocity or acceleration of the joint DOF.
</p>
<p>
Composite Force/Torque sensing:
</p>
<ul class="org-ul">
<li>Constraint force</li>
<li>Total force: gives the sum across all joint primitives over all sources: actuation inputs, internal springs and dampers.</li>

<p>
A transform sensor block measures the spatial relationship between two frames: the base <code>B</code> and the follower <code>F</code>.
</p>
<p>
It can give the rotational and translational position, velocity and acceleration.
</p>
<p>
The measurement frame should be specified: it corresponds to the frame in which to resolve the selected spatial measurements. The default is <code>world</code>.
</p>
<p>
If we want to simulate an <b>inertial sensor</b>, we just have to choose <code>B</code> to be the <code>world</code> frame.

<b>Force sensors</b> are included in the joints blocks.
