Hi, I am trying to compile modify interDyMfoam and create waveDyMfoam. I am getting following error.

waveDyMFoam.C:130:43: error: ‘ghRef’ was not declared in this scope
gh = (g & mesh.C()) - ghRef;


I want to know where is ghRef defined..

Thanks,

Manoj

Try going to your OpenFOAM source root, and searching for it. Start with OpenFOAM/src, and if it's not there, search OpenFOAM/applications

find -name "*.[HC]" | xargs grep ghRef

or

grep -r ghRef *

Thanks David for the reply.

I found that ghRef is defined in gh.H .

After including this in my code, I am now getting following error.

 In file included from waveDyMFoam.C:69:0:
../createFields.H: In function ‘int main(int, char**)’:
../createFields.H:83:18: error: redeclaration of ‘Foam::volScalarField gh’

Please help me to correct it. I am new to compiling these codes.

Hi,

did you included that gh.H file in your code?

It seems the error comes because you are defining it twice: when you include the H file and when you code it. Try to comment out your own definitions.

Hello Manoj and Agustino,

I am struggling at the same step.

I found this:
http://www.cfd-online.com/Forums/ope...c-meshing.html

And proceed to the opposite: in createFields.H
uncomment the two #include and comment the two solScalar and surfaceSaclar:

original:

//include "readhRef.H"
//include "gh.H"
#volScalarField gh("gh", g & (mesh.C() - referencePoint));
#surfaceScalarField ghf("ghf", g & (mesh.Cf() - referencePoint));

new:

#include "readhRef.H"
#include "gh.H"
//volScalarField gh("gh", g & (mesh.C() - referencePoint));
//surfaceScalarField ghf("ghf", g & (mesh.Cf() - referencePoint));

At least now it compiles and the floating run (crash after but might be another issue ^^)

The other solution I found is to copy-paste the definition of gh.H just before it is used in waveDyMFoam, but in removing the two last lines.

if (mesh.changing())
                {
                    Info<< "Execution time for mesh.update() = "
                        << runTime.elapsedCpuTime() - timeBeforeMeshUpdate
                        << " s" << endl;

        dimensionedScalar ghRef
            (
                mag(g.value()) > SMALL
              ? g & (cmptMag(g.value())/mag(g.value()))*hRef
              : dimensionedScalar("ghRef", g.dimensions()*dimLength, 0)
            );
            //volScalarField gh("gh", (g & mesh.C()) - ghRef);
            //surfaceScalarField ghf("ghf", (g & mesh.Cf()) - ghRef);

                    gh = (g & mesh.C()) - ghRef;
                    ghf = (g & mesh.Cf()) - ghRef;
                }

AND by adding

#include "readhRef.H"

in the main (just after #include "readWaveProperties.H")

This way i am not altering the createFields.H

The simulation runs and then crash the same (hopefully meaning it does not come from here)

Cheers
