-The presented formulation is applicable to any spatial dimensionality.
-For the purposes of this study we apply it in a 1D spatial reference system.
-Axis $x$ is along flow and axis $z$ is pointed upwards with a domain thickness of $L_z$.
-Shear deformation is restricted to occur in horizontal (x) shear zones.
-We assign depth coordinates $z_i$ and fluidity $g_i$ to a regular grid with ghost nodes and cell spacing $\Delta z$.
-The normal stress is assumed to increase with depth due to lithostatic pressure from the overburden ($\sigma_\text{n}(z) = \int^{z'=L_z}_{z'=z} \rho_\text{s} \phi G dz' + \sigma_\text{n,t}$), where G is the magnitude of gravitational acceleration and $\sigma_\text{n,t}$ is the normal stress applied on the top of the domain.

We apply the model in a one-dimensional setup where simple shear occurs along the horizontal axis $x$.
The vertical axis is denoted $z$.
The spatial domain is $L_z = 8$ m long and is discretized into cells with equal size to the representative grain size $d$.

We assign depth coordinates $z_i$, granular fluidity $g_i$, and fluid pressure $p_{\text{f},i}$ to a regular grid with ghost nodes and cell spacing $\Delta z$.
The fluidity field $g$ is solved for a set of mechanical forcings ($\mu$, $\sigma_\text{n}'$, boundary conditions for $g$), and material parameters ($A$, $b$, $d$).
