Hi, I need the vector values of an affine operator and solve. to get this i used

```julia
op_Disp = AffineFEOperator(a_Disp ,b_Disp ,fem_params.U_Disp ,fem_params.V0_Disp)
    uh_out = solve(op_Disp)
    return get_free_dof_values(uh_out)

```

i get a vector using this line but i want to be sure that is that the results of finite element solution or not?  
tnx
