Dear Wolfgang,
I had indeed a gap in understanding of some points, it is solved now! I
thank you a lot for your time and effort in trying to understand my problem
and to help me out!
With kind regards,
Mariia

Dear Wolfgang,
Thank you a lot for the reply! I am trying to implement the Biot equations
for the propagation of acoustic waves in porous media. The equations are
attached in the "Biot .PNG" file. There are two boundary integrals there,
containing information on work, done by external forces

Deal all,
I have an issue implementing Dirichlet boundary conditions in a mixed
pressure-displacement problem.
In step-20 there is an example for implementing pressure boundary
conditions like that:
*template *
*class PressureBoundaryValues : public Function
