There are two ways to define a Smooth task in the <span class = "ph">Tosca Structure.gui</span>:
</p></p></div>

<section><ol class = "ol steps"><li class = "li step stepexpand">

Using the <span class = "ph">Tosca Structure.pre</span> editor:
Insert a <span class = "ph uicontrol">SMOOTH</span> command block in the normal <span class = "ph">Tosca Structure</span>
optimization parameter file as shown in the figure below. If defined like this, <span class = "ph">Tosca Structure.smooth</span>
is called automatically once the optimization ends. Multiple <span class = "ph uicontrol">SMOOTH</span> blocks are allowed in the same parameter file resulting in
<span class = "ph">Tosca Structure.smooth</span> being called multiple times.
<br/><img class = "image" src = "../TsoUserImages/smooth_command_gui.png" width = "600"/><br/>

</li><li class = "li step stepexpand">

Using the dedicated <span class = "ph">Tosca Structure.smooth</span> editor:
A stand-alone execution of <span class = "ph">Tosca Structure.smooth</span>
can be started from the corresponding editor like shown in the figure. Simply load in the optimization results to use, optionally modify the default settings and click the <span class = "ph uicontrol">Start Smoothing</span> button.
<br/><img class = "image" src = "../TsoUserImages/smooth_gui_screen.png" width = "600"/><br/>

<div class = "itemgroup stepresult">
<p>
<span class = "ph">Tosca Structure.smooth</span>
can be rerun like this with modified parameters to obtain the desired results. The button
<span class = "ph uicontrol">View Result</span> opens a dialog for the resulting VTFX file to be opened in
<span class = "ph">Tosca Structure.view</span>.
</p>
</div>
</li><li class = "li step stepexpand">

In addition, you can start
<span class = "ph">Tosca Structure.smooth</span>
without a graphical interface directly from the command line using the following command:

<p>
<pre class = "codeblock">ToscaStructure post --smooth --opt &lt;smooth_parameter_file&gt;.par --job &lt;tosca_job_directory&gt;</pre>
<p>A suitable parameter file has the format</p>
<pre class = "codeblock">
<code class = "ph codeph">
SMOOTH
&lt;parameter1&gt; = &lt;value1&gt;
&lt;parameter2&gt; = &lt;value2&gt;
END_
</code>
</pre>
<div class = "note"><span class = "run-in.note">Note:
			</span><span class = "notecontent">
Manually creating the parameter file from scratch requires some experience. It is recommended to use and modify an earlier smooth parameter file created with the
<span class = "ph">Tosca Structure.gui</span>.
In most cases, then only the paths to the result files must be changed.
