Hi, I don't know about support for reading in second order elements as I understand it deal.II treats the mesh as the 'geometry' without specifying the FE order, which is done later. It is recommended that you read in a fairly coarse mesh and then refine a few times in deal.II since this is faster. I presume your concern is that you need the boundary of your cylinder to be represented well. The way to do this is to use a Boundary object to describe the shape you want, then when you refine in deal.II new nodes are placed correctly on the boundary. The second mesh in Step-1 shows how this can be done.
Hope this helps. Cheers, Michael On Fri, Mar 25, 2011 at 6:16 PM, Praveen C <[email protected]> wrote: > Hello all, > I am trying inviscid flow over a cylinder using DG scheme.
