Hey,
of course, if you have the same physics in both stokes domains, then you
can simply use a grid consisting of different patches. I assumed you
have different models of some sort - i.e. Stokes / stokesnc or similar.
Cheers,

Hi,
I don‘t think you need 3 models for the dumux multidomain in your
case. You can just use the default setup with a different grid. As you
just have Stokes and Darcy just make a grid that has some hole/channel
spared out (or whatever setup you want). For that you can use e.g. the
subgridmanager with dune-subgrid.
A grid doesn‘t need to be connected everywhere, it can also consist of
several disconnected patches. You would just need three domains if you
have for example Stokes-Darcy1p-Darcy2p or something.
Good luck

Hi Mr K,
from your email I understand that you created a second coupling
manager? So you have something like
CouplingManager<DarcyTypeTag, StokesTypeTag1> couplingManager1;
CouplingManager<DarcyTypeTag, StokesTypeTag2> couplingManager2;
?
MultiDomain currently requires a single coupling manager that knows
about all domains, with each domain having a unique domain id. In
general, this can be implemented by inheriting from two
specializations of a two-domain coupling manager. By specializations
I mean specialized for different pairs of domain ids. An example for
this is the FacetCouplingThreeDomainManager in
https://git.iws.uni-stuttgart.de/dumux-repositories/dumux/-/blob/master/dumux/multidomain/facet/couplingmanager.hh
Besides only inheriting, you need to do some overload resolution
efforts in the dderived three domain coupling manager. In the above
file, you can find examples for all of this.
For the StokesDarcy two-domain coupling manager, I guess the missing
piece is that the subdomain ids cannot be defined via template
parameters but are hardcoded to 0,1,2. You could try this locally by
simply moving them into the template arguments and use those wherever
the 0,1 or 2 are hardcoded.
Cheers,
Dennis

Hello,
I want to model porous medium with upper and lower free flow domain.
I use 2 domain darcy & stokes exercise for doing this.
I copy stokes problem and rename to stokes2 & change main.cc
<http://main.cc> file
In main.cc <http://main.cc>, I struct new coupling manager with
stokes2 TTag.
after making file only first of the stokes type tag recognized. and
raise error for another type tag.
how can I correct this problem?
Is there any example for 3 domain stokes - darcy - stokes ?
