Dear Christophe, Many thanks for your quick reply. It improves the mesh quality a lot, but not to the 'publishing quality'. I expect a symmetric pattern in the mesh to the two symmetric lines of the domain. I understand this might be achieved by deliberately dividing the domain into many subareas, but just wondering if there is a smart way for this. Any suggestions would be greatly appreciated.
Kind regards, Feifei <http://www.quotery.com/enjoy-the-little-things-for-one-day-you-may-look/> On 19 November 2014 19:17, Christophe Geuzaine <[email protected]> wrote: > > > On 19 Nov 2014, at 08:48, Feifei TONG <[email protected]> wrote: > > > > Dear All, > > > > I am working to create hybrid structured-unstructured quad mesh around > circular cylinders, similar to this in the chain of the email, as posted by > Rajib.
