&lt;p&gt;&amp;nbsp;&lt;/p&gt;
&lt;p&gt;I&amp;rsquo;m trying to simulate side by side of two identical ships using &amp;ldquo;Obstacle&amp;rdquo; option (&lt;strong&gt;Fig.1&lt;/strong&gt;). I put -obstacle after describe piece of vessel &lt;strong&gt;Bc&lt;/strong&gt; (Bc.ppo file attached). I compute &lt;strong&gt;&amp;amp;weight&lt;/strong&gt; for both vessels and check the equilibrium status, but I found the total weight and buoyancy for &amp;ldquo;obstacle vessel&amp;rdquo;, which is vessel Bc remain 0.00 (&lt;strong&gt;Fig.2&lt;/strong&gt;) . Also the panel generated of vessel Bc is 0 (&lt;strong&gt;Fig.3&lt;/strong&gt;), it gives all hydrodynamic properties of vessel B in output file are zero.&lt;/p&gt;
&lt;p&gt;So I came up with these question:&lt;/p&gt;
&lt;ol&gt;
&lt;li&gt;Is obstacle option make the vessel remain &lt;strong&gt;fixed&lt;/strong&gt; (do not move along with the floating object)?&lt;/li&gt;
&lt;li&gt;In the side by side cases we usually observe the &amp;ldquo;&lt;strong&gt;multibody effect&lt;/strong&gt;&amp;rdquo; from each body, not only the incident wave and diffracted wave on the lee side, but also the &lt;strong&gt;radiation wave&lt;/strong&gt; (relating to added mass and damping components) of those vessels. How to model multibody effect in MOSES?&lt;/li&gt;
&lt;/ol&gt;
&lt;p&gt;&lt;/p&gt;
&lt;p&gt;I also attached the side by side model below.&lt;/p&gt;

&lt;p&gt;I&amp;#39;m trying to understand the meaning of &amp;quot;BCN&amp;quot; and &amp;quot;ECN&amp;quot; stated in the MOSES Manual Chapter &amp;quot; &lt;span class="fontstyle0"&gt;IX.D.3 The &amp;amp;STRING String Function&amp;quot; (Page 80). There it is stated :&amp;nbsp;&amp;quot;For &lt;span class="fontstyle2"&gt;SUBSTR&lt;/span&gt;, the result will be the characters BCN through ECN of the input string, STRING(1).&amp;quot;. However no explanation in detail about BCN and ECN.&amp;nbsp;&lt;br /&gt; &lt;/span&gt;&lt;/p&gt;
&lt;p&gt;&lt;span class="fontstyle0"&gt;Could you explain more and give an example on how to use it?&lt;/span&gt;&lt;/p&gt;
&lt;p&gt;&lt;img style="max-height:240px;max-width:320px;" src="/resized-image/__size/640x480/__key/communityserver-discussions-components-files/343374/_2600_string.png" alt=" " /&gt;&lt;/p&gt;
&lt;p&gt;&lt;span class="fontstyle0"&gt;Thank you&lt;/span&gt;&lt;/p&gt;
