Hi all,

I'm working on a 3 million cell case of the DTChull tutorial. I've reworked the blockmesh and added a few more refinements in various toposets, as well as adding my own geometry and refining snappyhexmesh to add more refined boundary layers. But it still diverges. I'm suspecting that it could be the sixDoFRigidBodyMotion solver in my dynamicMesh Dict, but I don't have the experience to tell. Other possibilities are that my translation, rotation dampers are too high, but I would like to keep them low as I eventually plan on running through waves. Any suggestions on getting this to converge? Thank you for the help!
