Hi there,

I am trying to build a more complex domain with 3 blocks for a poroelastic problem. Everything works fine, but the closer analysis reveals, that there is no interaction (flow/pressure propagation/displacement across the matched faces. They act as if they were set to wall.
Do I have to adapt something in the constant/polyMEsh/boundaries files?

The manual tells, that just by ignoring the corresponding patches from the patches list would connect the corresponding blocks (5.3.2)

Any hints appreciated

Tom

By "try & error" I could "solve" the problem.
Instead of "face merging" by ignoring the correspondent patches from the patch list I explicitly connected the blocks by "mergePAtchPairs" and now everything works as one continuum ;-)

As to what I understood from the manual 5.3.2 both approaches should yield a complete connection! In my case only the merge approach yielded the desired result.

However the behaviour of "separated" blocks in the face matching approach could yield quite a nice way to reproduce some kind of "resistance to flow" as sheet piles (of course only in parts of the domain and not completely isolating it, as in my case) in the geotechnical engineering practice. I will check that.
