Detailed Description

Prescribes $u_i = d_{ij}(x_j-\bar{x}_j)$ or $s = d_{1j}(x_j - \bar{x}_j)$ where $ v_i $ are primary unknowns for the subscale.

Prescribes $v_i = d_{ij}(x_j-\bar{x}_j)$ or $s = d_{1j}(x_j - \bar{x}_j)$ where $ v_i $ are primary unknowns for the subscale.

This is typical boundary condition in multiscale analysis where $d = \partial_x s$ would a macroscopic gradient at the integration point, i.e. this is a boundary condition for prolongation. It is also convenient to use when one wants to test a arbitrary specimen for shear.
