This might be useful for convection dominated problems where steep gradients can often lead to oscillations in the solution variable. It is straightforward to create this in one's own application, but it might be nice to just have it already exist in the framework."},"comment":{"url":"https://api.github.com/repos/idaholab/moose/issues/comments/161773570","html_url":"https://github.com/idaholab/moose/issues/6013#issuecomment-161773570","issue_url":"https://api.github.com/repos/idaholab/moose/issues/6013","id":161773570,"user":{"login":"friedmud","id":870705,"avatar_url":"https://avatars.githubusercontent.com/u/870705?v=3","gravatar_id":"","url":"https://api.github.com/users/friedmud","html_url":"https://github.com/friedmud","followers_url":"https://api.github.com/users/friedmud/followers","following_url":"https://api.github.com/users/friedmud/following{/other_user}","gists_url":"https://api.github.com/users/friedmud/gists{/gist_id}","starred_url":"https://api.github.com/users/friedmud/starred{/owner}{/repo}","subscriptions_url":"https://api.github.com/users/friedmud/subscriptions","organizations_url":"https://api.github.com/users/friedmud/orgs","repos_url":"https://api.github.com/users/friedmud/repos","events_url":"https://api.github.com/users/friedmud/events{/privacy}","received_events_url":"https://api.github.com/users/friedmud/received_events","type":"User","site_admin":false},"created_at":"2015-12-03T20:29:36Z","updated_at":"2015-12-03T20:29:36Z","body":"I don't know about what you're proposing here... but a `ValueJumpIndicator`\n(jump in variable value across element edges for discontinuous basis\nfunctions) would be useful for DG and other purposes and should be added to\nMOOSE.\nOn Wed, Dec 2, 2015 at 1:19 PM John W.
