Evaluate the derivative of the 1st Piola-Kirchhoff stress tensor and assemble its contribution to the local gradient matrix 'A'.
- Parameters
-
[in] | Jpt | Represents the target->physical transformation Jacobian matrix. |
[in] | DS | Gradient of the basis matrix (dof x dim). |
[in] | weight | Quadrature weight coefficient for the point. |
[in,out] | A | Local gradient matrix where the contribution from this point will be added. |
Computes weight * d(dW_dxi)_d(xj) at the current point, for all i and j, where x1 ... xn are the FE dofs. This function is usually defined using the matrix invariants and their derivatives.
Implements mfem::TMOP_QualityMetric.
