fSUM: field Segmentation of Unstructured Meshes is an algorithm for partitioning a planar or volumetric domain, discretized through a mesh of any kind and with a scalar field defined on it, into a given number of regions in which the field is homogeneous.

To streamline and automate the build process, two scripts are provided:
build.sh: Designed for Unix-like systems, including Linux and macOS.build.ps1: Tailored for Windows systems.
Select the appropriate script for your operating system and execute it from its directory using the command line.
After that, launch the launcher.sh Bash script in each folder to automatically reproduce the paper results.
The following scripts are available:
