In addition, few studies have shown that microbial biofilms are formed in native rock matrixes at least in fracture zones, where the flux of water and nutrients is higher, or near the surface, where oxygen is present13,14,15. But up to now, there has been no information about the ...
Due to the complexity of fracture geometry, an unstructured mesh is needed. However, when the distance or the angle between the adjacent fractures is very small, tiny mesh elements are required to discretize the area between fractures, leading to computational difficulties. The pseudo-fracture model...
