In PR #7547 \r\nI implement the inner product (f,g) where f is second order Lagrange and \r\ng is first order Lagrange, so the integral is for a third order function. \r\n\r\nThe primal variable is first order Lagrange. Moose selects the quadrature order\r\nto integrate second order polynomials correctly. \r\n\r\nI should add that there was a discussion of the inner product (f,f) to not be integrated\r\nexactly with a significant error (exact answer = 0.4, actual answer = 0.3996). I increased the\r\nquadrature order manually and got the right answer. \r\n\r\n### Rationale for the enhancement or information for reproducing the error\r\nShould MOOSE take AuxVariables into account when selecting the quadrature rule?\r\n"},"comment":{"url":"https://api.github.com/repos/idaholab/moose/issues/comments/242416780","html_url":"https://github.com/idaholab/moose/issues/7616#issuecomment-242416780","issue_url":"https://api.github.com/repos/idaholab/moose/issues/7616","id":242416780,"user":{"login":"YaqiWang","id":6607496,"avatar_url":"https://avatars.githubusercontent.com/u/6607496?v=3","gravatar_id":"","url":"https://api.github.com/users/YaqiWang","html_url":"https://github.com/YaqiWang","followers_url":"https://api.github.com/users/YaqiWang/followers","following_url":"https://api.github.com/users/YaqiWang/following{/other_user}","gists_url":"https://api.github.com/users/YaqiWang/gists{/gist_id}","starred_url":"https://api.github.com/users/YaqiWang/starred{/owner}{/repo}","subscriptions_url":"https://api.github.com/users/YaqiWang/subscriptions","organizations_url":"https://api.github.com/users/YaqiWang/orgs","repos_url":"https://api.github.com/users/YaqiWang/repos","events_url":"https://api.github.com/users/YaqiWang/events{/privacy}","received_events_url":"https://api.github.com/users/YaqiWang/received_events","type":"User","site_admin":false},"created_at":"2016-08-25T14:51:49Z","updated_at":"2016-08-25T14:51:49Z","body":"FYI, removing that if causes one test failing:\r\n```\r\nbcs/nodal_normals.cylinder_hexes_2nd........................................................
