Development of a faultrupture environment in 3D: A

The isoblock in the model can represent a fault zone that is physically deformed due to the shear stress with nonzero thickness and a certain shape, which appears as a feature quite different from that of a fault structure simulated with a single planar or nonplanar interface in a numerical model.

Numerical modeling (geology) Wikipedia

In geology, numerical modeling is a widely applied technique to tackle complex geological problems by computational simulation of geological scenarios.. Numerical modeling uses mathematical models to describe the physical conditions of geological scenarios using numbers and equations. Nevertheless, some of their equations are difficult to solve directly, such as partial differential equations.
