◆ doWork()

MoFEMErrorCode SimpleContactProblem::OpGetNormalMasterALE::doWork ( int  side,
EntityType  type,
EntData data 
)

Evaluates unit normal vector to the master surface vector based on material base coordinates.

Computes normal vector based on material base coordinates based on mesh (moab vertices) coordinates:

\[ {\mathbf N}^{(2)}({\mathbf X}(\xi, \eta)) = \frac{\partial\mathbf{X}(\xi, \eta)}{\partial\xi}\times\frac{\partial \mathbf{X}(\xi, \eta)} {\partial\eta} \]

where \({\mathbf X}(\xi, \eta)\) is the vector of material coordinates at the gauss point on master surface with parent coordinates \(\xi\) and \(\eta\) evaluated according to

\[ {\mathbf X}(\xi, \eta) = \sum\limits^{3}_{i = 1} N_i(\xi, \eta){\bar{\mathbf X}}_i \]

where \( N_i \) is the shape function corresponding to the \( i-{\rm{th}}\) degree of freedom in the material configuration \({{\mathbf {\tilde X} }}_i\) corresponding to the 3 nodes of the triangular master face.
