I&#8217;m having trouble meshing a part with multiple bodies. What I&#8217;m trying to do is a static simulation for a vertical storage tank, it&#8217;s made up of 5 rings (different thickness, so I use 5 different bodies) and the roof (also multiple bodies). When using adaptive mesh size, the mesh in the tank shell is extremely strange (attached screenshot), not using it improves the mesh, but I cannot reach convergence because making the elements smaller is too much computational load (for this I require use adaptive size)<\/p>\n<p>I have tried:<br \/>1. Use shared topology<br \/>2. Use edge\/edge and face\/edge automatic contacts<br \/>3. Using a single body on the rings (improves, but I can&#8217;t assign different thicknesses this way)<br \/>4.
