Demonstrate how to solve 2D Poisson problem in fish-shaped domain.

{
 
 //Set up the problem with 4 node Poisson elements
 FishPoissonProblem<QPoissonElement<2,2> > 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);
 
 //Increment counter for solutions 
 doc_info.number()++;
 
 
} // end of main
