Hi all,
I combine two domains in one simulation.
I have coupledFvMatrix I found somewhere
on MB and in presentation for
Politecnico di Milano. It enables to
solve variables in not coupled domains. Like
temperature in solid and fluid(the example below).

coupledFvScalarMatrix TEqns(2);
new fvScalarMatrix
+ fvm::div(phi, T)
- fvm::laplacian(DT, T)
new fvScalarMatrix
- fvm::laplacian(DTsolid, Tsolid)

But this is not applicable to for example to
pressure - velocity coupled equations.
So it will not work for
fvVectorMatrix UEqn
+ fvm::div(phi, U)
- fvm::laplacian(nu, U)
solve(UEqn == -fvc::grad(p));

Did the implementation developed somewhere
furhter (I have version dated end of January)?
Is there maybe a coupled field class
(like coupledFvScalarField/coupledFvVectorField)?
Is there any other way to solve coupled fields
with different dynamics?
Thanks in advance,
