Ideally I would like to have an example mesh with one or two P2/P3 triangles in 2D, one P2/P3 tetra in 3D and so on.\n  From your description on the wiki, I don't understand how to write a curved mesh to a file. Looking at escher-p2.mesh, for example, it seems that only the vertices of the tetra and boundary triangles are given in connectivity sections. Does it mean that the mesh nodes have to be indexed so that the first N nodes are only P1 vertices and the remaining nodes of the mesh (with index higher than N) are the additional nodes?\n It's not clear to me what is the ordering convention in the 'FiniteElementSpace' section and what do the numbers actually mean. You say that the mesh description is 'based on a vector finite element grid function with degrees of freedom in the \"nodes\" of the mesh'. What function? Some values are smaller than -1 or bigger than 1, so I suppose it's not Lagrange shape function values that you store here. Does 'nodes' mean all nodes (i.e. higher-order nodes included)? How are they indexed - is there any correspondence with the node ordering in the 'elements' section? Could you please provide a sketch or an example of a __very__ simple mesh file for each element shape? Deciphering your conventions from a 3D mesh with more than 10 elements is just too hard.\n\nMfem supports discontinuous elements. Is it possible to store a discontinuous \nmesh, i.e. mesh where each element has it's own degrees of freedom not shared \nwith its neighbours, in native mfem file format?\n\n Thank you for your help and for making glvis opensource.\n\nBest regards,\n\n   Martin Vymazal\n```\n\nOriginal issue reported on code.google.com by `Martin.V...@gmail.com` on 25 Dec 2013 at 12:00"},"comment":{"url":"https://api.github.com/repos/GLVis/glvis/issues/comments/224623381","html_url":"https://github.com/GLVis/glvis/issues/7#issuecomment-224623381","issue_url":"https://api.github.com/repos/GLVis/glvis/issues/7","id":224623381,"user":{"login":"hdigonnet","id":19821485,"avatar_url":"https://avatars.githubusercontent.com/u/19821485?v=3","gravatar_id":"","url":"https://api.github.com/users/hdigonnet","html_url":"https://github.com/hdigonnet","followers_url":"https://api.github.com/users/hdigonnet/followers","following_url":"https://api.github.com/users/hdigonnet/following{/other_user}","gists_url":"https://api.github.com/users/hdigonnet/gists{/gist_id}","starred_url":"https://api.github.com/users/hdigonnet/starred{/owner}{/repo}","subscriptions_url":"https://api.github.com/users/hdigonnet/subscriptions","organizations_url":"https://api.github.com/users/hdigonnet/orgs","repos_url":"https://api.github.com/users/hdigonnet/repos","events_url":"https://api.github.com/users/hdigonnet/events{/privacy}","received_events_url":"https://api.github.com/users/hdigonnet/received_events","type":"User","site_admin":false},"created_at":"2016-06-08T15:19:37Z","updated_at":"2016-06-08T15:19:37Z","body":"Sorry to reopen this thread, but I was wondering if you could deal with arbitrary order curved mesh?\r\nI saw Linear,Quadratic, Cubic keywords, but how I could specify p4 curve element?\r\n\r\nThanks also for the comment about how you number dof, that helps me a lot.
