I have not been able to find the issue. I am considering looking for an
alternative. I am using 2 components to describe a complex solution (for real
and imaginary parts). Assuming that I keep the ordering by default and that I
export my solution vector (to work in an external software), what I need in
the end is to know for each value of the solution vector, if it corresponds to
the real or imaginary part. I realized by debugging that the order is not
consistent and it changes depending on the number of dof.
I would like to ask if there is any function or if you could suggest a way to
get the vector that contains information about the component type for each
node (for example a mask type, where 0 is real and 1 imaginary component). The
way I implemented and managed the components, assembly, etc is identical to
the one described in step-29.
Yes, there are a number of functions in namespace DoFTools that you can use to
extract the indices of DoFs based on their vector component.
