a, Overview of a lobing pair of pavement cells. A transfacial patch of anisotropic material is located in one cell while the rest of the material in both cells is isotropic. b, The material in the connected anticlinal wall in the same cell is also defined as anisotropic. Note that no transition zone near the edges of the patch is used. c, The anisotropic patch has a width of 2μm, and the simulated MF direction is aligned with the arrows. d, Maximum principal stress map after pressurization and relaxation for the completely isotropic case; this result serves as a reference for the deformation. e, Stress map for the case which includes the anisotropic patch, which shows a stress concentration within the patch area. f,g, Comparison of the cell-cell interface geometry for the isotropic (reference – green) and anisotropic (magenta) models.
