### 2.7.1 Screen output

By default, FEBio will print convergence and progress information to the screen that informs users how the analysis is progressing. The output depends on the particular module and solver that was chosen in the FEBio input file, as well as some user-defined settings, but in general provides the following information.
• Time stepping information: The current time step that FEBio is solving and a notification when the time step completed (or an error message why the time step failed to complete)
• Convergence information: for each time step, FEBio usually has to solve a nonlinear problem for which an iterative nonlinear solver is used. Several “norms” are printed to inform the user how FEBio is progressing toward the solution of the nonlinear problem.
• Summary: At the end of the analysis a summary is printed with heuristics that inform the user how well the model ran.
By default, all screen output will also be printed to the log flie.
