Hi deal.ii community,
I am having a little issue with a (smart) design of a (not so simple)
multiscale FEM. The problem in its simple form is the following: I have a
coarse mesh and on each coarse cell I replace the standard basis (for
example Q1) with basis functions that reflect some
Thank you so much. I will have a look!

Dear Dr. Bangerth,
Thank you for the quick reply! After installing LAPACK, the code works!
Thanks,

Thanks for this suggestion - I will have a go at this as well.

HI Bruno,
That is correct. How would i use fe_values.get_function_values to
interpolate though? Since I have to get the values off of domain 1 only (as

Where can i get theory behind step-8? Can anyone suggest any book?

Dear Chandra,
For me, one of the most instructive textbooks on linear elasticity (and that
fundamentals of FEM) is this one:

title = {The Finite Element Method: Linear Static and Dynamic Finite
Element Analysis},
publisher = {Dover Publications Inc.},

Dear all,
I am trying to solve the equations in step-20 with inhomogeneous neumann
bcs on one of the boundaries and getting something very bizarre.
I have a rectangular domain with the following:
1. Top boundary has homogeneous conditions: this is applied into the weak
form like in step-20
Thanks a lot. I will go through it.

Essentially There is no need in changing anything in assemble_system
function from step-8.
At least for stiffness matrix, you should change boundary conditions and
triangulation to suit for your task,
that is all. However you should not mix up Young's modulus with Lame
parameters which are
ingomogeneous neumann BC are imposed through including them into a
stiffness matrix.
You should not use MatrixTools::apply_boundary_values for this purpose I
guess.
Look the Step-7 trutorial for the info on how to calculate boundary
integral for neumann BC.

your hints are highly appreciated. I will work on creating my own data

though I made some tests with "almost" zero volumes cohesive interfaces and
they are indeed simple and effective. So, if there is a chance
