No, it returns a vector of Tensor<1,dim> objects. If you want the gradients of
the displacement vector, you need
Hi Michael,
The problem here is that “scratch.solution_grads_u_total” is initialised with
the cell FEValues, and so has n_cell_quadrature_points entries. You need to
pass
"scratch.fe_face_values_ref[u_fe].get_function_gradients(scratch.solution_total,
scratch.solution_grads_u_total);”
fe_face_values.*get_function_gradients *returns a rank 2 tensor as the
solution is the displacement vector.
Let me be more specific. In the code gallery " Quasi-Static Finite-Strain
Compressible Elasticity (The deal.II Library: The 'Quasi-Static
Finite-Strain Compressible Elasticity' code
The return type should be `*Tensor<2,dim,NumberType>*` shouldn't it?
Hope this helps. If not, could describe how the code does not work? It it
not compiling? Is the result wrong?
