Fig. 18: Computational conditions, domain and meshing.
Schematic of the a experimental apparatus used by Xu et al.44 to expose F/M specimen to static liquid Li, b corresponding computational domain consisting of a polycrystalline material with the initial values and boundary conditions, c finite element mesh of the whole computational domain, and d enlarged area corresponding to the red square in c highlighting the finite element size within the grains and along the GBs in the expected area of interface propagation. The exposed surface is the upper most boundary.
