Hi,
Is there support for several mappings to one interface and vice versa? I have a mixed dimensional situation that looks a bit like this:
Solver A: = (2D)
Solver B: x (1D)
Domain:
===========
=xxxxxxxxx=
===========
The domain of Solver B is completely embedded in the domain of Solver A as it is formulated as a problem in a lower dimension. Solver B has a 1D domain/mesh and solver A a 2D domain/mesh. What I tried to do was:
 define two interfaces (
interfaceATop
andinterfaceABottom
) for Solver A (interface above and below Solver 2)  define one interface (
interfaceB
) for Solver B
I defined four mappings

interfaceATop
>interfaceB

interfaceABottom
>interfaceB

interfaceB
>interfaceATop

interfaceB
>interfaceABottom
However, preCICE complained that I cannot have several mappings to the same interface. I guess that is caused by interfaceB
showing up everywhere.
Question
Is this a conceptual issue or did I do something wrong when setting up my coupling? I understand that having two times the same mapping would not make sense, but I map to pairwise different interfaces.
Current solution
I solved this at the moment by defining two interfaces interfaceBTop
and interfaceBBottom
which works as intended, but I have a bit more of administration to do myself. I did not save my first preCICEconfiguration thus I cannot attach it here.
Thanks in advance!
