◆ doWork()

MoFEMErrorCode MetaSpringBC::OpGetTangentSpEle::doWork ( int  side,
EntityType  type,
EntData row_data 
)
virtual

Evaluates the two tangent vector to the triangle on surface with springs based on material base coordinates.

Computes the two tangent vectors, \( {\mathbf T}^{(1)} \) and \( {\mathbf T}^{(2)}\), based on material base coordinates based on mesh (moab vertices) coordinates:

\[ {\mathbf T}^{(1)}({\mathbf X}(\xi, \eta)) = \frac{\partial\mathbf{X}(\xi, \eta)}{\partial\xi} \;\;\;\; {\mathbf T}^{(2)}({\mathbf X}(\xi, \eta)) = \frac{\partial \mathbf{X}(\xi, \eta)} {\partial\eta} \]

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

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

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