The residual norm is different between the master-app's final value and the very next line of the output, \"Picard Norm after TIMESTEP_END MultiApps.\" These two values should be the same because there are no  timestep_end multi-apps.\r\nThe output looks something like this:\r\n\r\n>  2 Nonlinear |R| = 3.993301e-16\r\n> Solve Converged!\r\n> Picard Norm after TIMESTEP_END MultiApps: 1.0843e-08\r\n\r\nSo somewhere between those two residual evaluations, _t gets changed such that the time-dependent kernel changes the residual.\r\nThis can cause the simulation to continue the Picard Iteration loop until the maximum number of iterations has been reached.\r\n\r\n### Information for reproducing the error\r\nAn example with the error is included in the attached files.\r\n\r\n### Identified Impact\r\nPicard Iteration with time-dependent materials or kernels."},"comment":{"url":"https://api.github.com/repos/idaholab/moose/issues/comments/237076551","html_url":"https://github.com/idaholab/moose/issues/6865#issuecomment-237076551","issue_url":"https://api.github.com/repos/idaholab/moose/issues/6865","id":237076551,"user":{"login":"permcody","id":3036960,"avatar_url":"https://avatars.githubusercontent.com/u/3036960?v=3","gravatar_id":"","url":"https://api.github.com/users/permcody","html_url":"https://github.com/permcody","followers_url":"https://api.github.com/users/permcody/followers","following_url":"https://api.github.com/users/permcody/following{/other_user}","gists_url":"https://api.github.com/users/permcody/gists{/gist_id}","starred_url":"https://api.github.com/users/permcody/starred{/owner}{/repo}","subscriptions_url":"https://api.github.com/users/permcody/subscriptions","organizations_url":"https://api.github.com/users/permcody/orgs","repos_url":"https://api.github.com/users/permcody/repos","events_url":"https://api.github.com/users/permcody/events{/privacy}","received_events_url":"https://api.github.com/users/permcody/received_events","type":"User","site_admin":false},"created_at":"2016-08-02T23:04:52Z","updated_at":"2016-08-02T23:04:52Z","body":"@snschune - This may be related to your problem.\r\n"}}
