Dear Anup,
one option you have is to use a Triangulation.
I would still use two scalar extractors:
const FEValuesExtractors::Scalar u_x
const FEValuesExtractors::Scalar u_y
Tensor<2,dim+1> gradient;
gradient[0] = fe_values_ref[u_x].gradient(k, q_point)
gradient[1] = fe_values_ref[u_y].gradien
Anup,
I am solving for a 3 dimensional displacement vector (*dim+1* dimensional)
in a *dim=2* dimensional space (for
a planer problem in elasticity). Hence I consider an FEvaluesExtractor:
const FEValuesExtractors::Vector u_fe;
and initialize it as
u_fe(0)
Now I need to compute the gradie
