Elena,
I would like to modify step-14 and calculate stress at nodes, but I found
step-14 complicated and also unfortunately my c++ is not good :(
Yes, step-14 is not the best example of a tutorial program :-(
I would like to add stress_strain_nodal_values method to classes Base,
PrimalSolver and WeightedResidual ( similar to output_solution() ) then inside
template <int dim> void Framework<dim>::run (const ProblemDescription
&descriptor) invoke it by solver->stress_strain_nodal_values()
The problem is if I do so, inside stress_strain_nodal_values() method I can
not extract required data to calculate stresses from this pointer. For example
this->quadrature returns ambiguity error or I do not have access to fe_value
to calculate stress.
What exactly is the error? You may have to qualify access as in
this->PrimalSolver<dim>::quadrature ()
to specify whether you want the quadrature formula from the primal or dual
solver. Similarly for the other variables and functions that are declared in
the base class.
Best
W.
