how to generate cylinder field in cellSetDict?
Hello,
I would like to generate a floating object with cylinder shape, how should I setup the cellSetDict? Regards, T |

Thanks very much, I will give it a try with cylinderToCell.

Hi Eystein,
I tried cylinderToCell but the shape of the cylinder looked really strangehttps://docs.google.com/drawings/d/1...DW5AXeEmY/edit, could you help me with this? https://docs.google.com/drawings/d/1...DW5AXeEmY/edit Regards, Li |

Have you tried to make the cells smaller in this region? It is possible that the cells in this region are too larger to make it better "looking". |
Hi again,
The cells you mean is the mesh size around this region or the cylinder size? I set the shape of the cylinder based on a physical experiment so I can not change the size of it. Btw, the simulation cashed down at about 3.5s since floating point exception issue, do you have any idea about how to solve it? Regards, |

What I mean is that your cylinder selection is created from the cell in your domain. So if you have large cells in your domain the cylinder surface will not be smooth. If you want to create an solid cylinder inside your domain, then it is probably easier to do that using a cad software and mesh everything, including the cylinder. |
