Insert

mesh.schemesDict().setFluxRequired(p().name());

after

const fvMesh& mesh = fluidSolver::mesh();

...into:
src/fluidSolidInteraction/fluidSolvers/consistentIcoFluid/consistentIcoFluid.C
src/fluidSolidInteraction/fluidSolvers/icoFluid/icoFluid.C
src/fluidSolidInteraction/fluidSolvers/pisoFluid/pisoFluid.C

Then I ran ./Allwmake to update and the tutorial ran fine. RH.

The above will work, but if you have dependencies built upon fsifoam, for example some of the Chalmers OpenFoam stuff, this will not work. Specifically I tried it for "An opensource solver for wave-induced FSI problems" by Huang and had troubles. A more clean way is to follow the pictures I've attached.
p { margin-bottom: 0.25cm; line-height: 120%; }

Hello,
I have added the line on the scripts but the tutos on fsiFoam don't work, (error : flux requested but p not specified in the fluxRequired sub-dictionary of fvSchemes )

does any one have another trick or solution ??

Hi Xena,
include the following line of code to the source code of your fluid solver. Typically in the evolve section, after the fvMesh definition. Hope that helps.

mesh.schemesDict().setFluxRequired(p().name())

Hello, I am having same issue.

flux requested but p not specified in the fluxRequired sub-dictionary of fvSchemes.

    From function fvMatrix<Type>::flux()
    in file lnInclude/fvMatrix.C at line 1046.

FOAM aborting

Aborted (core dumped)

When I add this line:

   mesh.schemesDict().setFluxRequired(p.name());

to foam-extend-4.0/FluidSolidInteraction/src/fluidSolidInteraction/fluidSolvers/icoFluid/icoFluid.C and/pisoFluid.C

    // Prepare for the pressure solution
    label pRefCell = 0;
    scalar pRefValue = 0.0;
    setRefCell(p_, fluidProperties(), pRefCell, pRefValue);
   mesh.schemesDict().setFluxRequired(p.name());

I get in terminal:

fluidSolvers/pisoFluid/pisoFluid.C:271:40: error: ‘((Foam::fluidSolvers::pisoFluid*)this)->Foam::fluidSolvers::pisoFluid::p’ does not have class type

Can someone point me to the right direction?

I also would like to add, I changed fvMatrix.c regarding to the post in this thread. But I don't know where to type "wmake libso" so I used "./Allwmake" in foam-extend-4.0/src. Is it wrong?

It took like 4 days, finally works...
