Dear Wolfgang,
thanks for your detailed explanation and also for the proposed solution. I
will think about this possibility.
Best,
Dustin

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.

I am using step-8 to build 2d cantilever beam.Can anyone help me whether it

Dear all,
I am trying to solve the equations in step-20 with inhomogeneous neumann

I have a rectangular domain with the following:

form like in step-20
2.
Thanks a lot. I will go through it.

Dear Chandra,
For me, one of the most instructive textbooks on linear elasticity (and that
fundamentals of FEM) is this one:
@Book{Hughes2000a,
title = {The Finite Element Method: Linear Static and Dynamic Finite
Element Analysis},
publisher = {Dover Publications Inc.},
year = {2
Where can i get theory behind step-8? Can anyone suggest any book?

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

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 whatever
