My questions are listed below:<\/div>\n<ol>\n<li>The cells of the CV consist of&nbsp;<strong>hexa\/prism+tetra(Multizone method)<\/strong>; is Remeshing valid for this kind of mesh method?<\/li>\n<li>I only know that the &#8220;Fluid-solid-wall&#8221; should be set to &#8220;system coupling&#8221;; I don&#8217;t know what I should assign for inlet, outflow, symmetry of 3 boundaries, and free surface.
