Description

This repository contains three compressed archives:

  • meshes.zip
    Contains MATLAB .mat files with the finite element (FE) models corresponding to different numbers of degrees of freedom (DOFs). 

    • 10k_preprocessing.mat
    • 30k_preprocessing.mat
    • 100k_preprocessing.mat
    • 300k_preprocessing.mat

  • matlab_scripts.zip
    Provides the main MATLAB scripts implementing the different model order reduction (MOR) methods.

    • MOR_Cylinder_validated_IRCA_longrun.m
    • MOR_Cylinder_validated_MM_longrun.m
    • MOR_Cylinder_validated_res_longrun.m
    • MOR_Cylinder_validated_TOAR_longrun.m

  • matlab_functions.zip
    Includes the auxiliary MATLAB functions required by the scripts for the MOR procedures.

Usage Instructions

To ensure proper execution, extract all three .zip files into the same directory. After extraction, update the MATLAB paths in the scripts if necessary so that all functions and data files are correctly referenced.
