As you suggested I tried to define fenders the keep the piston inside the cylinder. I have two component one is piston, and the other one is cylinder. The cylinder&#8217;s inner radious is R1=50 mm, and piston&#8217;s radious is R2=48 mm. Piston&#8217;s top surface distance to the waterline is H1=155 mm, and Piston&#8217;s bottom surface distance to the waterline is H2=175 mm.&lt;\/p&gt;&lt;p&gt;I defined 8 connection point for each component to define fenders.For cylinder they are:&nbsp;(R1,0,-H1),(0,R1,-H1),(-R1,0,-H1),(0,R1,-H1), and for the piston they are:(R2,0,-H1),(0,R2,-H1),(-R2,0,-H1),(0,R2,-H1). These are for the top side I also did the some thing for the bottom side with H2.&nbsp;&lt;\/p&gt;&lt;p&gt;1-Are they should be floating fender or fixed?Can I define the distance between piston and cylinder like 2 mm. Is this gap to small?&lt;\/p&gt;&lt;p&gt;2-To get result from Hydrodynamic Diffraction I had the delete one of the inner surface. If I dont delete the surface , I had to divide into two component and use to joint. But with joint, I guess I had another problem during the Hydrodynamic responce so this time I just delete it.&lt;\/p&gt;&lt;p&gt;<img loading=\"lazy\" decoding=\"async\" src=\"https:\/\/innovationspace.ansys.com\/forum\/wp-content\/uploads\/sites\/2\/2024\/10\/24-10-2024-1729766535-mceclip3.png\" width=\"255\" height=\"321\" \/>&nbsp;&lt;\/p&gt;&lt;p&gt;3- Should I define Interracting structure groups to get result in Hydrodynamic responce.&lt;\/p&gt;&lt;p&gt;<img loading=\"lazy\" decoding=\"async\" src=\"https:\/\/innovationspace.ansys.com\/forum\/wp-content\/uploads\/sites\/2\/2024\/10\/24-10-2024-1729766600-mceclip4.png\" width=\"238\" height=\"146\" \/>&lt;\/p&gt;&lt;p&gt;4-Diactivated freedom for both structure on X,Y,RX,RY.
