Hi all,
I am trying to use the helper tools to assemble a system for a vector valued
problem.
I am looking to have 2 or 3 displacement DoFs.
So I use
FESystem<dim> fe;
and initialize with
fe(FE_Q
<https://www.dealii.org/current/doxygen/deal.II/classFE__Q.html><dim>(1), dim)
So my code compiles, but when I try and run I get the following....
--------------------------------------------------------
An error occurred in line <182> of file
</build/deal.ii-KebjEf/deal.ii-9.2.0/include/deal.II/numerics/vector_tools_project.templates.h>

void dealii::VectorTools::internal::project_matrix_free(const dealii::Mapping<dim, spacedim>&, const dealii::DoFHandler<dim, spacedim>&,

dealii::LinearAlgebra::distributed::Vector<Number>::value_type>&, dealii::LinearAlgebra::distributed::Vector<Number>&, bool, const
dealii::Quadrature<(dim - 1)>&, bool) [with int components = 2; int fe_degree = 1; int dim = 2; Number = double; int spacedim = 2; typename
dealii::LinearAlgebra::distributed::Vector<Number>::value_type = double]
The violated condition was:
dof.get_fe(0).n_components() == function.n_components
Additional information:
Dimension 2 not equal to 1.

Using some crude debugging it is complaining about the create_mass_matrix call.
Now I know there are two variants. I was trying to create the matrix without
passing a mapping but that is generating this error. My issue is I am not sure
how to create a mapping that works.
How does one make a mapping for a system? I looked at some of the tutorials but
I could not find what I am looking for....
Thanks in advance.
