This repository contains a collection of gmsh mesh file txt files containing the x-y data of each plot associated with the work "Nine circles of elastic brittle fracture: A series of challenge problems to assess fracture models" The gmsh mesh files are ready to be used in FEM simulations as explained in the paper. The txt files contain post-processed data extracted from the FEM results ready to be plotted. Detailed naming conventions and file descriptions are provided in the README included with this dataset.
