Detailed Description

Applies a mean deviatoric shear rate and pressure (Neumann boundary condition). Introduces unknowns for the deviatoric stress, and this boundary condition adds contributions to both the left and right hand side of the system. The approach expresses the deviatoric stresses/strain(rates) in a special (nonsymmetric) base;

\[\boldsymbol A_{\mathrm{dev}} = \sum_{i=1}^{n} A_{\mathrm{dev},i} \boldsymbol E_i \]

where the bases \( \boldsymbol E_i \) can be chosen as

\[\boldsymbol E_1 = \frac{1}{\sqrt{2}}\begin{pmatrix}1 & 0 \\ 0 & -1\end{pmatrix}, \quad \boldsymbol E_2 = \begin{pmatrix}0 & 1 \\ 0 & 0\end{pmatrix}, \quad \boldsymbol E_3 = \begin{pmatrix}0 & 0 \\ 1 & 0\end{pmatrix}. \]

in 2D, and

\[\boldsymbol E_1 = \frac{1}{\sqrt{6}}\begin{pmatrix}2 & 0 & 0\\ 0 & -1 & 0 \\ 0 & 0 & -1\end{pmatrix}, \quad \boldsymbol E_2 = \frac{1}{\sqrt{2}}\begin{pmatrix}0 & 0 & 0\\ 0 & 1 & 0 \\ 0 & 0 & -1\end{pmatrix}, \quad \boldsymbol E_3 = \begin{pmatrix}0 & 1 & 0\\ 0 & 0 & 0 \\ 0 & 0 & 0\end{pmatrix}, \ldots\quad \boldsymbol E_8 = \begin{pmatrix}0 & 0 & 0\\ 0 & 0 & 0 \\ 0 & 1 & 0\end{pmatrix} \]

in 3D (in 1D no deviatoric component exists).

Either bulk elements + side number can be used, or a boundary element (line in 2D, surface in 3D) can be used directly.

Note: The 2D case assumes plane strain(rate), as is the case in _2dFlow.; This is only applicable to momentum balance equation. Both solid or fluids, incompressible or compressible, should work.; Should typically be prescribed on the entire external boundary of an representative volume element.; Should be applied to element boundaries, not DOFs.; The implementation doesn't assume that the stress is symmetric, so rigid body rotations are automatically removed.; Rigid body translations must be controlled separately.
