I have several questions about how to implement the 1D fracture flow in a 2D
solid domain in deal.ii.
1. How do I discretize the 1D fracture flow?
2. If I use a FE_Q<1> for fracture flow, it seems like I should distribute u
dofs and p dofs separately. In this way, how can I consider the coupling
effect of the displacement u and pressure p?
3. How deal.ii deal with problems with different dimensional configurations
(like 2D for solid deformation and 1D for fluid flow)?
4. Is there any example in the tutorial related to my problem?
I will be grateful for any help you can provide.
Chong Liu:
You'll have to mix 1d and 2d triangulations and find ways to couple them. I
think that what you are trying to do is quite close conceptually to what
step-60 does. You might also want to take a look at step-70 for alternative ideas.
