Hi, I am going to use affineFEoperator and solve for linear plasticity the out put of this is singlefieldfunction while using matrix form and dividing a/b of weak form gives a vector form. I need the vector solution of solve function. could you please tell me how can I get this?  
output of affine and solve  
code

```julia
op_Disp = AffineFEOperator(a_Disp ,b_Disp ,U_Disp ,V0_Disp)
    uh_out = solve(op_Disp)

```

```julia
SingleFieldFEFunction():
 num_cells: 9280
 DomainStyle: ReferenceDomain()
 Triangulation: BodyFittedTriangulation()
 Triangulation id: 9088478837478427212

```

out put of division  
code

```julia
A_mat = MatrixA(pth; phys_params, fem_params) 
b_vec = assemble_vector(v->(∫(v)fem_params.dΓ_s), fem_params.V)
u_vec = A_mat \ b_vec

```

```julia
0.08119110240868146 + 42.59321094887059im
 0.24208798306755652 + 42.64391602396656im

 0.14577061602716654 - 7.756775745095706im

```

ps. results are not for the same problem  
due to this i cant do vector operation on output of solve function

If I understood correctly, you might do the following:

```julia
uh = FEFunction(fem_params.U_disp, u_vec)

```

To get out a `CellFunction`, to then operate on this data type
