It happened after a few iterations, not immediately.&nbsp;&lt;br&gt;I tried to make a better mesh but it still didn&#8217;t work so I tried to simplify the shape of the tank in order to understand if the problem was the imported CAD or whatever.&lt;br&gt;With the simplified shape the quality of the mesh seemed okay (I put a photo of the parameters and the shapes) <img decoding=\"async\" src=\"https:\/\/innovationspace.ansys.com\/forum\/wp-content\/uploads\/sites\/2\/2024\/12\/21-12-2024-1734770869-photo_5992453034577347102_y.jpg\" alt=\"\" \/>&lt;\/p&gt;&lt;p&gt;In the setup in Ansys fluent I put the right setting because when I tried the first sloshing analysis in a glass-shaped object, it did work fine.
