Getting started#

Requirements#

  1. MATLAB

  2. matlab2tikz (optional)

General process#

A startscript loads the desired input-file. This input-file includes all necessary parameters for the given mechanical problem (geometry, loads, initial values,…), the chosen numerical integration scheme (time-step size, method, simulation time), the Postprocessing routine (plot quantities, animation, export) and the solution parameters for Newton’s method. Metis creates all necessary objects and computes the approximate solution based on the given parameters. Eventually, one can choose to have an animation of the solution, some plots are created and the results are being exported.

First steps#

  1. Clone this directory or download the .zip folder

  2. Get matlab2tikz (optional)

  3. Open the MATLAB editor or run it with the shell script metis.sh

  4. Open start_metis_single_analysis.m

  5. Adjust <input_file_name> corresponding to a file from /input, for more info look at README_input.md

    [simulation, system, integrator, solver] = Metis('input/<input_file_name>',1,1);

  6. Adjust the path to the matlab2tikz directory in the chosen input-file

  7. Execute start_metis_single_analysis.m for a first simulation

  8. Edit or change input file or create a new one in /input

  9. For error analyses run start_metis_error_analysis.m with corresponding input-file

  10. Have fun!
