wmake error while adding T to icoFoam

Hello,

I am trying to modify currently available solver in OpenFoam. http://openfoamwiki.net/index.php/Ho...ure_to_icoFoam So, I found a great tutorial on how to implement temperature into icoFoam, which is currently available.

I am having a little trouble wmake-ing the solver. After following the tutorial in detail, I was not able to compile the solver. Instead, the following came up as error. I only see one error and that is colored in red. I would like some insights from those who have already tried this particular tutorial or have implemented their own solver.

By the way, I am using OpenFoam 2.0, the newest.

Thanks so much for your time.

Ah ha,

I figured it out. Simple mistake on my part.

Hi Brad,
same problem here, but can't crack it. Could you please explain the solution!

To finish this off!
Another freaking blind copy-paste error. In createFields.H:

Code:

volScalarField T

(

    IOobject

    (

        "T",

        runTime.timeName(),

        mesh,

        IOobject::MUST_READ,

        IOobject::AUTO_WRITE

    ),

    mesh

);

Hi everybody

I'm new in OpenFOAM and C++ and I'm trying to modify an available solver to solve a cross derivative equation. But unfortunately I'm getting the similar error while wmake-ing the solver:
no matching function for call to ‘Foam::fvMatrix<Foam::Vector<double> >

The modified solver is:

Code:

#include "fvCFD.H"



// * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * //



int main(int argc, char *argv[])

{

       #include "setRootCase.H"

       #include "createTime.H"

       #include "createMesh.H"

       #include "createFields.H"



       // * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * //



       Info<< "\nStarting time loop\n" << endl;



       while (runTime.loop())

       {



               Info<< "Time = " << runTime.timeName() << nl << endl;



        fvVectorMatrix TEqn

        (

                  (fvc::grad(phi) & vector(1,0,0)))            

        );



        solve( TEqn ==  -s);



            Info<< "ExecutionTime = " << runTime.elapsedCpuTime() << " s" << " ClockTime = " << runTime.elapsedClockTime() << " s" << nl << endl;



            Info<< "Estimating error in scalar poisson equation" << endl;





        runTime.write();

              Info<< endl;



          } // Fin Error



          Info<< "End-loop\n" << endl;





          return 0;



}

Does anybody know how can I fix the problem?
Please excuse me because of my poor English.
Thank you for your help

Code:

fvVectorMatrix TEqn

        (

                  (fvc::grad(phi) & vector(1,0,0)))            

        );

at least two errors:
1) extra ")"
2) inner product of two vector is an Scalar, so it should be "fvScalarMatrix"

Thank you for your consideration

But unfortunately I'm still receiving the same error message even after correcting the mentioned errors. The new one is:

Code:

fvScalarMatrix TEqn         

(                   

           (fvc::grad(phi) & vector(1,0,0))                  

);

But I think the problem is somewhere else because when I change the code like to the following it works properly:

Code:

fvScalarMatrix TEqn         

(

                  fvm::laplacian(phi)

                - fvm::laplacian(phi)

                 (fvc::grad(phi) & vector(1,0,0))                     

);

Any help?

uhum
thats right, because you use "fvc"
fvc convert a field to another field, it does not make any matrix

Thank you Nima
yes , you are right, but it's still supposed to work because both sides are scalar fields. So why doesn't it work?
Let's talk about something simpler. Even following code couldn't be compiled:

Code:



        fvScalarMatrix TEqn

        (

               fvc::grad(phi)

        );

        solve( TEqn ==  -s);

both sides are scalar fields
what's the reason?

because fvc::grad(phi) does not make the matrix of coefficient, it is a known and definite variable, it is like you put for example a variable T = s , which both T and s has value :)

I appreciate your help Nima, I found the problem

Actually I was trying to solve Winslow equation by OpenFOAM:

αxξξ − 2βxξη + γxηη = 0

but it seems that it's impossible.
Does anybody know if there is a way to solve it by OpenFOAM?

Hi everybody

any idea to handle cross derivatives (like xξη) in OpenFOAM?
