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 on the fluid and skeleton part of
the media. I want to implement fixed displacement boundary conditions
("BC.PNG") on a part of the geometry with ID = 2, so I need to set the
displacement components to zero. I was wondering, whether there is a way to do
it similarly to the way it"s done in step-20 example for the pressure boundary
condition (so, in the local_rhs vector).
Maria: so which of the terms in that formula are you interested in implementing?
Best
W.
