This is a big mistake because WATER3 has a huge Shear Modulus, while real water has zero Shear Modulus. This will cause a large error in your results.&nbsp; Delete the Inside body and instead use the faces of the solid elements that define the inside cavity surface to create <a href=\"https:\/\/ansyshelp.ansys.com\/public\/account\/secured?returnurl=\/Views\/Secured\/corp\/v242\/en\/ans_elem\/Hlp_E_HSFLD242.html\" rel=\"external noopener noreferrer\">HSFLD242 elements<\/a>.&lt;\/span&gt;&lt;\/p&gt;&lt;p&gt;&lt;span class=&#8221;&rdquo;&rdquo;&rdquo;&rdquo;structname&rdquo;&rdquo;&rdquo;&rdquo;&#8221;&gt;HSFLD242&lt;\/span&gt; is used to model fluids that are fully enclosed by solids (containing vessels).
