Uh, what I want to do is to use deal.ii to simulate our own model,
Before using deal.ii , I used some numerical simulation software like
abaqus.
However, it will be very difficult to use abaqus to simulate seepage flow
and multiphase coupling.
I tried to use deal to build a simple model to

Thanks, Wolfgang, I think reading some PDE knowledge materials would help
me to solve the constitutive equation problems.
I try to read the create_point_source_vector() class in deal.ii

Nick,
If I want to modify the constitutive equation based on step-8, but I can't
understand the expression you described in step8, like this.

Which aspect of knowledge should I learn if I want to modify the constitutive
equation.
This is a question that goes beyond what we can
Thanks Wolfgang,
I think you are correct! I just tried to use petsc_full_matrix instead and
it linked no problem!

Ah sorry, yes I have done that already. Sorry for forgetting that
detail...
If it should work assuming I have added my new directory in
source/CMakeLists.txt, maybe my implementation is the problem. Though, I
wouldn't know why since it fails at linking.

Zachary,
You also need to make sure that CMake actually sees that your new source
directory. In particular, you should add a line saying
ADD_SUBDIRECTORY(Test)
to source/CMakeLists.txt.
Best,
Daniel

Hi folks,
I am trying to add another include/source directory and subsequent obj to
dealii for potential future contributions to dealii. Though I am having
linking errors because my new obj needs to link agains the lac_obj (need
Trilinos and other interfaces). I thought the ADD_DEPENDICIES

Thanks, Wolfgang, I would like to try it later.

Which aspect of knowledge should I learn if I want to modify the
