Text S1. Model calibration
Gerke et al. (2018) calibrated this method. In addition, we explored the
effect of resolution with Test 4 as an example with voxel size of
~2.3 and ~4.6 µm. The difference between
two simulations is <3% for intrinsic permeability,
<2% for effective permeability, and <2% for
normalized permeability. This indicates that the trends demonstrated in
this study (Figure 2) is credible.
