The model is composed of 12 layers and the initial 11 layers are solid and I have been trying to use the hydrostatic fluid extension to make the last layer a fluid.<\/p>\n<p>A few issues I am having are:<\/p>\n<ul>\n<li>The mesh works by using a symmetry &#8211; however when solved for a force, the centre layer (fluid) sinks in on itself. Additionally, the model splits at the boundaries of symmetry and when a moment is applied the boundaires overlap.<\/li>\n<li>Is the hydrostatic fluid element the best method for making the central layer an incompressible fluid?<\/li>\n<li>Trying to use a cyclic region as part of the symmetry however a static structural system seems to not agree with it.<\/li>\n<\/ul>\n<p>Posted a few pictures below.
