Output types

The various output types are presented in the Outputs - library section. Check the available outputs and their Fortran structure.

Result directory : structure

The results are written in a res subdirectory of the working directory. The general /res structure should be :

        run_YYYY-MM-DD_HH:MM:SS    # Text file with run informations
        energy.plt                 # Post-treatment files : balance of energy, volume, etc.
        /bin                       # General binary outputs
        /vtk                       # General vtk    outputs
        /savefield_1d              # Specific 1D    outputs (XY datafiles)
        /savefield_2d              # Specific 2D    outputs (binary or vtk)

The result subdirectory contains :

  • a run information file
  • post-treatment files (if w_post = 1 in the input.txt file) : energy.plt, energy_init_final.csv, umax.plt, volume.plt
  • a bin subdirectory with general binary outputs
  • a vtk subdirectory with general vtk outputs
  • a savefield_1d subdirectory regrouping all the one dimensional specific results (state of the wanted fields at a specific point of the domain during a time interval)
  • a savefield_2d subdirectory regrouping all the two dimensional specific results (state of a subdomain during a time interval)


Some outputs need to be post-treated. The post-treatment tools will be presented in the following paragraphs.


As presented before, one could generate binary files and csv files with Tolosa-sw.

PyTolosa is a Python post-treatment tool which enables the user to post-treat two-dimensional data from binary files, and one-dimensional data from csv files. Two running modes are available : an interactive mode and a batch mode. The interactive mode enables the specifications to be asked as the program moves forward. On the other hand, the batch mode needs the specifications to be given by running arguments.

Installation and presentation

Please check how to install and use PyTolosa in the documentation.

One can obtain the following post-treatment images and animations :



ParaView is an open-source, multi-platform data analysis and visualization application. ParaView users can quickly build visualizations to analyze their data using qualitative and quantitative techniques. Here, this tool is used to read .vtk files bundle to analyse 2D outputs generated by Tolosa-sw.

ParaView enables us to create the following animations and views :
