Hi Mike,
Thanks for the reply.
Any hint on how to easily reproduce the shape function calculations by hand

Are you using FIRST and SECOND, LAGRANGE variables? If so, are you also
changing the mesh when you switch back and forth between orders?

Hi John,
I am still struggling and running out of ideas here.
I wrote down some debugging - perhaps you can find something weird.
The calculations seem correct, at least to what I could understand so far.
But things are zero'ing out.
If, in the mesh creation, I declare the variable as "FIRST" or
Hi John,
_sys_solution is the system->solution vector.
It is fed by:
_system.solution->localize_to_one( _sys_solution );

Hi,
I need some help here ...
I am having trouble to understand what is going on with a boundary integral.
I have solved a Poisson problem for pressure in a 2D mesh, as a model for a
incompressible water flow in porous media.
The mesh (Tri6 elements) has a near-circular polygon in the middle
