[LThomes]

Hello,
I'm trying to control the Courrant number and my ajustTimeStep is not working. So I think i have to modify the icoFoam.C to be able to make it work. However, I'm facing some trouble.
I'm following this tutorial http://www.tfd.chalmers.se/~hani/kur...tersReport.pdf to create a new solver "myIcoFoam".
So I've done these steps:
_____________________________________

sol
cp -r incompressible/icoFoam/ $WM_PROJECT_USER_DIR/applications/solvers/
cd $WM_PROJECT_USER_DIR/applications/solvers
mv icoFoam myIcoFoam
cd myIcoFoam
mv icoFoam.C myIcoFoam.C
sed -i s/icoFoam/myIcoFoam/g myIcoFoam.C
sed -i s/icoFoam/myIcoFoam/g Make/files

To set the library path right, do following change in Make/files:
change
EXE = $(FOAM_APPBIN)/icoFoam
to
EXE = $(FOAM_USER_APPBIN)/myIcoFoam
And also change in Make/options:
-I../dieselEngineFoam \
to
-I$(LIB_SRC)/../applications/solvers/combustion/dieselEngineFoam \
____________________________________________

I did not understand this last step very well, so I wrote this:

EXE_INC = \
    -I$(LIB_SRC)/finiteVolume/applications/solvers/lnInclude \
    -I$(LIB_SRC)/meshTools/applications/solvers/lnInclude

EXE_LIBS = \
    -lfiniteVolume \
    -lmeshTools

The previous "options" was:

EXE_INC = \
    -I$(LIB_SRC)/finiteVolume/lnInclude \
    -I$(LIB_SRC)/meshTools/lnInclude

EXE_LIBS = \
    -lfiniteVolume \
    -lmeshTools

Finally, I'm getting the following error:

[ofuser@default myIcoFoam]$ wmake
Making dependency list for source file myIcoFoam.C

myIcoFoam.C:63:19: fatal error: fvCFD.H: No such file or directory

Can anybody help me? I'm using OpenFOAM for Windows, so I'm fiding it a little bit difficult to modify these things

Clearly, the directory I put in bold does not exist, so you are bound to get an error!
The -I option should link to the directory that contains some common OF headers... This should be exactly the same for both icoFoam and my_icoFoam, so it is very simple what you need to do there: don't touch anything.

This replacement:

-I../dieselEngineFoam \
to
-I$(LIB_SRC)/../applications/solvers/combustion/dieselEngineFoam \

links your copied solver to the original solver, allowing you to use its header files, rather than copying them.
Clearly, this is a nicer thing to do (as you don't have to duplicate unnecessary things), but I recommend you don't do so, as you are not yet comfortable with making those judgment calls.

Whereas I like Windows for the "normal" things, Linux beats Windows by far when we talk about software development.

[LThomes]

floquation,
Thanks for your prompt reply. But if I don't touch anything in the "options", I have the following error:

[ofuser@default myIcoFoam]$ wmake

It's not my choice to use Windows xD

[floquation]

That's not an error.

When a compiler is called, it shows you the entire command. That's what the Makefile does.

The three lines you see right there do the following:

1. It finds the dependencies of myIcoFoam, such that it can compile the dependencies before compiling myIcoFoam. You have no dependencies that need compilation, so it then proceeds with:
2. It compiles myIcoFoam.C to Make/.../myIcoFoam.o
3. It links Make/.../myIcoFoam.o, which gives you the executable myIcoFoam in $FOAM_USER_APPBIN

If you'd now type "wmake" again, it will show you "myIcoFoam is up to date", which indicates that everything was successful.

[LThomes]

Thank you so much. I'm so used to getting error messages, that I thought it was another one

[akidess]

Did you go through all these hoops just to control the time step? Why not use pimpleFoam?

I didn't know that the ajustTimeStep would work with pimpleFoam, if it works it's a great idea indeed. Thank you.

[LThomes]

Hello again,
Now I'm trying to modify the myIcoFoam.C file to enable the ajustTimeStep. This is what I did:

int main(int argc, char *argv[])
{
    #include "setRootCase.H"
    #include "createTime.H"
    #include "createMesh.H"

    pisoControl piso(mesh);

    #include "createFields.H"
    #include "initContinuityErrs.H"
	

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

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

    //while (runTime.loop())	// dropped
	while (runTime.run())       // added
    {
		#include "readTimeControls.H"	// added
		#include "setDeltaT.H" // added

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

        #include "CourantNo.H"

        // Momentum predictor

        fvVectorMatrix UEqn
        (
             .
             .
             .

But when I try to compile it, this message appears:

The readTimeControls.H has the following lines:

maxCo =
    runTime.controlDict().lookupOrDefault<scalar>("maxCo", 1.0);

maxDeltaT =
    runTime.controlDict().lookupOrDefault<scalar>("maxDeltaT", GREAT);

Could anybody help me fix this error?

[floquation]

You are missing

    #include "createTimeControls.H"

next to createTime.H etc.

You can easily figure that out by opening a solver that supports this, like pimpleFoam or interFoam.

I actually did that, I can't believe I missed that line, I'm sorry >.< . Thank you very much for your patience.

Hi Kevin, Actually what LThomes did (modifying the Make/option file)is one of the solution posted in web to solve the errors which are related to compiling new solver. I almost tried all the ways!
now, I am trying to compile new solver (first exercise only changing the name and the Make/file) and when I execute the wmake command, I receive the following error:

make: *** No rule to make target '/opt/OpenFOAM-dev-debug/platforms/linux64GccDPInt32Debug/applications/solvers/incompressible/my_icoFoam/my_icoFoam.C.dep', needed by '/opt/OpenFOAM-dev-debug/platforms/linux64GccDPInt32Debug/applications/solvers/incompressible/my_icoFoam/my_icoFoam.o'. Stop."

Thank you in advance

Hi, your explanation made me at least understand the main steps of compilation thx
i am facing a problem when trying to compile my own modified movingConeTopFvMesh which existed in openfoam4 and 5. I followed the steps to change the name of C and H file, their contents, as well as edit Make/file and run wmake. But it output errors:

When I run wmake in openfoam4,

wmakeLnInclude: linking include files to ./lnInclude
make: *** No rule to make target '/opt/openfoam4/platforms/linux64GccDPInt32Opt/applications/topoChangerFvMesh/topoChangerFvMesh/topoChangerFvMesh2.C.dep', needed by '/opt/openfoam4/platforms/linux64GccDPInt32Opt/applications/topoChangerFvMesh/topoChangerFvMesh/topoChangerFvMesh2.o'.  Stop.

When i run wmake libso in openfoam5,

wmakeLnInclude: linking include files to ./lnInclude
make: *** No rule to make target 'Make/linux64GccDPInt32Opt/topoChangerFvMesh/JH_topoChangerFvMesh.C.dep', needed by 'Make/linux64GccDPInt32Opt/topoChangerFvMesh/JH_topoChangerFvMesh.o'.  Stop.

i tried to wclean and allwmake in src dir, and got some error output at the end of compilation.

I tried uninstall and re install openfoam4, and even tried compiling my new class to openfoam5. But both of them didn't work.
May i get some advice here on how to solve this? thanks a lot

hi, i'm getting the exactly same message as you. Do you solve your problem? Do you mind to share here? thanks

you need to replace the icoFoam with my_icoFoam in the my_icoFoam.C
sed -i 's/icoFoam/my_icoFoam/g' my_icoFoam.C

Now using the above mylinearSpring.so library file when I try to run my floatingObject example it give me error in blockMesh utility
