Investigation of the hybrid model coupling by comparing a simulation without clustering or re-solution with a stand-alone MARMOT simulation; (a) shows the initial microstructure; (b) and (c) show the final microstructure predicted by the stand-alone MARMOT simulation and the coupled simulation, respectively. They are shaded by the gas fraction and in (c) this includes the gas from both Xolotl and MARMOT. The interfaces are shown in black. (d) shows a plot of the intergranular bubble fraction versus time for the two simulations
