◆ doWork()

MoFEMErrorCode SimpleContactProblem::OpCalContactTractionOverLambdaSlaveSlave::doWork ( int  row_side,
int  col_side,
EntityType  row_type,
EntityType  col_type,
EntData row_data,
EntData col_data 
)

Integrates and assembles Lagrange multipliers virtual work, \( \delta W_{\text c}\) derivative with respect to Lagrange multipliers with respect to Lagrange multipliers on slave side and assembles components to LHS global matrix.

Computes linearisation of integrated on slave side complementarity function and assembles Lagrange multipliers virtual work, \( \delta W_{\text c}\) with respect to Lagrange multipliers

\[ {\text D} {\delta W^{(1)}_{\text c}(\lambda, \delta \mathbf{x}^{(1)}})[\Delta \lambda] \,\, = \int_{{\gamma}^{(1)}_{\text c}} -\Delta \lambda \delta{\mathbf{x}^{(1)}} \,\,{ {\text d} {\gamma}} \]

where \({\gamma}^{(1)}_{\text c}\) is the surface integration domain of the slave surface, \( \lambda\) is the Lagrange multiplier, \(\mathbf{x}^{(1)}\) are the coordinates of the overlapping gauss points at slave triangles.
