Inclusion Catalog Overview
The inclusion catalog is an attempt to develop intuition about how changes in rheology can affect the stresses on a fault surface, and the warping of a fault surface.
We build a model with a vertical planar fault. Rock properties are uniform throughout the model, except for an inclusion located near the fault. The inclusion is more rigid than the surrounding material.
We have run this model with inclusions of several different shapes, to develop an intuition of how the shape of rock units can affect stresses and warping on the fault.
Fig. 1. Finite element mesh. The mesh measures 380 km by 280 km by 129 km deep. The fault is a vertical plane that bisects the mesh, shown as a red line. The purple square in the center shows the location of the inclusion. The purple square is 25 km on a side
The smallest cells are cubes 625 meters on a side (hence the inclusion is 40 cells across). The smallest cells are too small to be seen clearly at this scale. The mesh contains about 850,000 cells, all of which are quadratic hexahedra.
Fig. 2. Close-up of center of mesh. The inclusion lies within the purple square, which measures 25 km across. The red line is the fault. The smallest cells are 625 meters on a side.
