I think this could be the solution to the convergence problem. \r\n\r\nIf anyone could give me a clue due to I'm new using this awesome code, I have another problem trying to set the velocity field. I want to do a compression model using two indentors. Is there anyway to move only the black blocks of the image? I don't know if the problem is because I define with the \"fn.shape.Polygon\" option\r\n\r\nthank you very much for your time and experience\r\n\r\n\r\n![slabimage_particle0000](https://cloud.githubusercontent.com/assets/18324577/15821800/5cfd421c-2bf2-11e6-9522-8f3d00263894.png)\r\n"},"comment":{"url":"https://api.github.com/repos/underworldcode/underworld2/issues/comments/227371660","html_url":"https://github.com/underworldcode/underworld2/issues/145#issuecomment-227371660","issue_url":"https://api.github.com/repos/underworldcode/underworld2/issues/145","id":227371660,"user":{"login":"AngelValverdePerez","id":18324577,"avatar_url":"https://avatars.githubusercontent.com/u/18324577?v=3","gravatar_id":"","url":"https://api.github.com/users/AngelValverdePerez","html_url":"https://github.com/AngelValverdePerez","followers_url":"https://api.github.com/users/AngelValverdePerez/followers","following_url":"https://api.github.com/users/AngelValverdePerez/following{/other_user}","gists_url":"https://api.github.com/users/AngelValverdePerez/gists{/gist_id}","starred_url":"https://api.github.com/users/AngelValverdePerez/starred{/owner}{/repo}","subscriptions_url":"https://api.github.com/users/AngelValverdePerez/subscriptions","organizations_url":"https://api.github.com/users/AngelValverdePerez/orgs","repos_url":"https://api.github.com/users/AngelValverdePerez/repos","events_url":"https://api.github.com/users/AngelValverdePerez/events{/privacy}","received_events_url":"https://api.github.com/users/AngelValverdePerez/received_events","type":"User","site_admin":false},"created_at":"2016-06-21T08:16:43Z","updated_at":"2016-06-21T08:16:43Z","body":"Now, before resolving the stokes problem, I can plot the velocityField, but when it is solve, appears a error message:\r\n\r\nRuntimeError: Error encountered.
