  //Set up the problem with nine-node  Poisson elements
  FishPoissonProblem<QPoissonElement<2,3> > problem;
  
  // Setup labels for output
  //------------------------
  DocInfo doc_info;
  
  // Set output directory
  doc_info.set_directory("RESLT"); 
  
  // Step number
  doc_info.number()=0;
 
 
  
  // Solve/doc the problem
  //----------------------
 
  // Solve the problem
  problem.newton_solve();
  
  //Output solution
  problem.doc_solution(doc_info);   
 
} // end of main
