[deal.II] Trying to interpolate deal.ii solution to a Cartesian grid
Hello, I have a solution on an unstructured grid obtained by deal.ii in VTU format, and now I want to interpolate it to a cartesian grid for further processing in other softwares. It seems like Paraview can do the job, but I'm wondering if this can be done in deal.ii directly? Thank you!

[deal.II] Re: Dimension Mismatch
Took a brief hiatus. and managed to pass a huddle following Marc's
suggestion.
Now I have set to construct convergence tables for the polymer flow problem
I am solving. It involves solving a Stokes Problem for velocity and
pressure (u,p), (size dim+1) and the Constitutive Equations for the stress
tensor tau, (size dim*dim). The solution has 7 components for dim=2.
To calculate the errors, I need the exact solution [(u,p), tau], ( size dim
+1 + dim*dim). To pick the correct component I use the
ComponentSelectFunction:
const ComponentSelectFunction
velocity_mask(std::make_pair(0, dim), dim*dim+dim+1);
const ComponentSelectFunction
pressure_mask (dim, dim+3);
const ComponentSelectFunction
stress_mask(std::pair(dim+3, dim*dim+dim+1), dim*dim+dim+1);
Now the errors that I am getting are:

Hello Jack,
the error message is quite descriptive and tells you that something is off
with the number of components of your Function object:
*The violated condition was: exact_solution.n_components ==

Check line 200 of your code:
ExactSolution () : Function(dim+1) {}
You call the constructor for Function with 3 components (since dim=2 in
your case). However, your implementation returns 7 components. Make sure
that you call the constructor with the right number of components.

Re: [deal.II] Re: Dimension Mismatch
Jack:
You are creating a Function=Function<7>, but that is not right.
The template argument denotes the number of components of the *input* vector
'x' for which you want to evaluate 'f(x)'. It does not denote the number of
*output* vector components. It should only be ComponentSelectFunction.
