Initial conditions for the models of the manuscript "Simulating major element diffusion in garnet using realistic 3D geometries" from Dominguez et al. 2025

Initial conditions used in the manuscript "Simulating major element diffusion in garnet using realistic 3D geometries" from Dominguez et al. 2025. Each file corresponds to a model at a specific resolution. EGM corresponds to euhedral garnet model, OGM to open garnet model, and IMM, to isolated matrix model. Three resolutions are included: 256^3, 512^3, and 768^3. Each file is a JL2D file containing five 3 arrays: the compositions in Mg, Ca, Fe and Mn in the garnet domain and the location of the contact between the garnet domain and the matrix domain as a binary matrix. These files can be read with the package JL2D.jl.
