coupledFvVectorMatrix
 

Dear all,

I have tried to search the forum for coupleFv<Type>Matrix or similar strings, however, without any luck. I am currently looking into programming a solver, which as a start solves the RANS on the one mesh and the Darcy equations in another mesh. I would like to make use of the coupleFvVectorMatrix for the momentum equation and pressure equations, as I presume that the PISO-loop will be easier to implement if both U and p are solved on the same _coupled_ mesh.

The question is that in single mesh configurations, you write

while solving the momentum equation, however, what is the corresponding syntax, when I need to compute the pressure gradient on two meshes, e.g. both fvc::grad(p0) and fvc::grad(p1).

Any help is appreciated,

Niels
