by updated you mean you pulled the recent version and installed the deal.II
via Spack?

I might be late to the party,
But I believe what Wolfgang is trying to say is that Q1-Q1 elements are
bi-linear. Consequently, except if you mesh is perfectly alligned with the
x and y axis, you will have a non-zero second derivative of the shape
function.
Your shape function are of the form : a

Hi everyone,
I am trying to implement an adaptive mesh refinement scheme for the Step-35
examle program.
I implemented the mesh-refinement acording to the Step-26 tutorial.
So I proceeded in the refine_mesh function as follows:
1. Create a Solution_Transfer object for each Vector;
2. prepare ref

This is pretty strange, since you say that the same code compiles on other
machines. From what I can tell from a brief search of this error message, it
typically appears when there is a stray brace or comma or the like. Are you
completely sure that source files on this problematic

machine.
When I try to compile my deal.ii based project I get puzzling errors. The
compiler has already compiled all the files of the project and put them
