GWM is a standalone software package based on the algorithm published in: "A greedy algorithm for wavelet-based time domain response spectrum matching" (Nie, Graizer, and Seber, Nuclear Engineering and Design, 410(112384), 15 August 2023; https://doi.org/10.1016/j.nucengdes.2023.112384)

• Dependencies
• GWM Installation
  • Binary Files
  • Dependencies (DLL Files)
• Tests

The current binaries are compatible with Python 3.12, which can be installed from either python.org or Anaconda3. Other Python versions may work with minor modifications to the source code.

Note: Install the following packages only if Python 3.12 is installed using the installer from python.org. Anaconda3 includes all these packages by default, but commercial use requires purchasing a license.

Required packages:

numpy ~= 1.26.4
scipy ~= 1.13.1
matplotlib ~= 3.9.2
PyQt5 ~= 5.15.10
pillow ~= 10.4.0

1. Copy the entire GWM folder to a location on your local drive
2. Add that folder to your PYTHONPATH environment variable (create the variable if it doesn't exist)

The package includes three Python extension modules with .pyd file extensions. These are Fortran codes compiled using mingw64 for Python 3.12:

• If you are using Python 3.12: You can use these files directly
• If you are using other Python versions: You will need to recompile the Fortran source files located in the gwm/fsrc folder (batch files are provided for compilation)

The mingw64_deps folder contains several .dll files from the compiler. These files are required by the .pyd modules and should be copied to the same folder as the .pyd files. If you recompile the Fortran source code, these .dll files are not needed.

Two test scripts are provided in the tests folder to demonstrate how to create starting scripts for using GWM:

• Benchmark_RspMatch09_example.py
• test_RG1.60.py

To execute these scripts, use the following commands in a CMD window or PowerShell prompt:

python Benchmark_RspMatch09_example.py
python test_RG1.60.py
