Detailed Description

Total Lagrangian formulation with most homogenization terms (one disp_xyz field and one scalar) The macro_gradient variable is split into two scalars: the first component called '_hvar' herein and all other components called '_avar' herein.

For parameter _beta = 0, the primary scalar (_kappa) is _hvar and the coupled scalar is _avar. For parameter _beta = 1, the primary scalar (_kappa) is _avar and the coupled scalar is _hvar. Just like the primary field variable (_var) is either disp_x or disp_y or disp_z depending on _alpha.

Thus, each instance of HomogenizedTotalLagrangianStressDivergenceR acts on one field variable (_disp_alpha) and one scalar variable (_hvar_beta). The job of the kernel is to assemble the residual of all dofs of _disp_alpha and of all dofs of _hvar_beta (namely, selected rows). Also, it assembles the ENTIRE row for _disp_alpha and _hvar_beta (namely the columns from all dofs of all _disp field variables and all dofs of all scalar variables _hvar and _avar). The rows for the other field/scalar variables are handled by other instances of the kernel, according to the flags compute_scalar_residuals and compute_field_residuals. When compute_field_residuals is given, only component=_alpha matters and beta = {0,1} is looped. When compute_scalar_residuals is given, only prime_scalar=_beta matters and alpha = {0,1,2} is looped.

In summary, for x=disp_x etc. and h=_hvar and a=_avar, then the contributions of the instances are _alpha=0 R = [Rx, 00, 00, 00, 00 ]^T J = [Jxx, Jxy, Jxz, Jxh, Jxa] _alpha=1 R = [00, Ry, 00, 00, 00 ]^T J = [Jyx, Jyy, Jyz, Jyh, Jya] _alpha=2 R = [00, 00, Rz, 00, 00 ]^T J = [Jzx, Jzy, Jzz, Jzh, Jza] _beta=0 R = [00, 00, 00, Rh, 00 ]^T J = [Jhx, Jhy, Jhz, Jhh, Jha] _beta=1 R = [00, 00, 00, 00, Ra ]^T J = [Jax, Jay, Jaz, Jah, Jaa]

In this manner, the full R and J are obtained with NO duplication of jobs: R = [Rx, Ry, Rz, Rh, Ra ]^T J = [Jxx, Jxy, Jxz, Jxh, Jxa Jyx, Jyy, Jyz, Jyh, Jya Jzx, Jzy, Jzz, Jzh, Jza Jhx, Jhy, Jhz, Jhh, Jha Jax, Jay, Jaz, Jah, Jaa]
