groovyBC in openFOAM-2.0 for parabolic velocity bc
 

Hi,

I'm using in openFOAM-2.0 on a 3D case groovyBC to perform this parabolic inlet velocity profile:

U(0,y,z)=Um*y*z*(H-y)*(H-z)/h^4
V=0
W=0

where Um=4*U(0,H/2,H/2,t)

What I've implemented is:

in
{
type groovyBC;
variables "yp=pts().y;zp=pts().z;minZ=min(zp);maxZ=max(zp);H =(maxZ-minZ)/2;U@in=4*U(0,H,H)*normal();";
valueExpression "U*yp*zp*(H-yp)*(H-zp)/pow(H,4)";
}


and I got the following error message:

--> FOAM FATAL IO ERROR:
cannot find file

file: /Users/soledad/OpenFoam/soledad-2.0.0/run/Cylinder/incompressible/icoFoam/system/controlDict at line 0.

From function regIOobject::readStream()
in file db/regIOobject/regIOobjectRead.C at line 73.

FOAM exiting

As in the wiki says, I've added in the contolDict: libs ( "libgroovyBC.so" ) ;
Could you help me please?

Thank you

The problem is that there is no controlDict there (you're trying to run the solver in the directory of the sources not in a case-directory). It's got nothing to do with groovyBC

Hi,

thank you for your quick response. But I don't understand what should I do. I've copied the folder groovyBC on a case directory and I've try to run the case again, but I still get the same error. This is the path:

~/OpenFoam/cases-2.0.0/run/Cylinder/incompressible/icoFoam/cylinder_00/groovyBC

Please, would you mind to explain it to me again?

Thank you

solOF

The original error message said basically "there is no control dict here". That has nothing to do with groovyBC

You don't have to copy the folder with the groovyBC-sources to the case. groovyBC has to be compiled once (see the instructions on the Wiki-page - the swak-page if you're using the groovyBC from there)

Then you'll have to prepare the case as described (also there) and you should be in business

Hi,

thank you. I've already compiled groovyBC but I got the following:

It seems not to find .H files. I'm working with Mac and with openFOAM-2.0. I have Bison 2.3.

At the beginning I compiled groovyBC and I got the following error:

PatchValueExpressionDriver.C:192: error: expected unqualified-id before ‘::’ token

PatchValueExpressionDriver.C:202: error: expected unqualified-id before ‘::’ token

then I remove the Foam:: in these two lines.

Could you help me please?

Thank you

Sorry, I forgot to add the error that I have when I'm running the case:

thank you

It seems that you're using the "old-school" groovyBC from http://openfoamwiki.net/index.php/Contrib_groovyBC

Have a look at the top of the page. There it says that support for this is discontinued with 2.0

I'm using Mac.

Could you help me?

Thank you

What precisely do you mean with "have already installed"

The utilities are the last part the compilation script compiles. What happens with the Libraries

The error messages you posted are not very helpful. What happens once g++ is called?

That is because it didn't compile properly

That is a general misconfiguration of the case. A symmetryPlan only allows symmetry-BC

Hi,

thank you. I've already corrected the problem with the symmetryPlane BC.

Related to compilation: I have download swak4Foam and as it says in the wiki, I've compiled the files with wmake all, however I have many problems, since some files cannot be opened. Could you help me? This is the first part of the compilation error. It seems no to find the libraries:

a) what are the first errors of the "real" compilation (from g++)

b) what does
ls $FOAM_SRC/OpenFOAM/lnInclude/PrimitivePatchMeshData.C
say (is the file found)

c) what does
ulimit -a
say (because if the rest of the compilation works this might be an issue with the number of file-descriptors)

Thank you for the help.

The problem is solved. I need to change the extension ".so" by ".dylib" and openFoam is finding the library :)

solOF

Can you explain where you have changed the extension ".so" by ".dylib" ?
I have the same problem

In the controlDict, where you call to your function, change the extension .so by .dylib, for example: forces.dylib

Thanks, that solved my problem :)

Is that on a Mac? Which version of OF-patches for that do you use? The one I published replace ".so" with ".dylib" on the fly. So you can keep "libfoo.so" in the files and OF will look for "libfoo.dylib". That way the case works on Linux and MacOSX

inlet { type groovyBC; variables "yp=pts().y;minY=min(yp);maxY=max(yp);para=-(maxY-pos().y)*(pos().y-minY)/(0.25*pow(maxY-minY,2))*normal();"; valueExpression "10*(1+0.5*sin(500*time()))*para"; value uniform (10 0 0); }

The above is an example for groovxyBC in OFwiki. The valueExpression shows a time-dependent variable. I supposed it's for velocities. Why is a constant velocity vector specified at the end?

You mean "value uniform (10 0 0);"? That is there to keep Paraview and other tools that don't know groovyBC happy

Hi Bernhard,

I have the same problem trying to compile swak4foam: Am I missing some package? Some infos:
- OF-2.1.x
Best regards,
Ilya

Hm. That is a rather old version of swak you're using. Isn't it? According to the source repository I fixed this last december and since then there have been at least 3 releases.

Anyway. This is only because you have no mercurial installed and doesn't affect the rest of the compilation anyway (the script generates the header file with the version information and in the end it would have said "oh. that didn't change" and left the file alone).

But do yourself a favour: get the latest version

The version was 0.2.3 (next to last according to Swak4Foam-Wiki) and suitable to OF up to 2.2 (2.1 is the one I use).

Now I've got v0.2.4 (release, available via svn, must be the latest one), but the errors are still there.

There are also a couple of other error related to openmpi (see attachment for the full log). Somehow, swak is looking for the "OF-internal" openmpi, while an external is used. I think I'm missing something.

Best regards,
Ilya

Have you ever tried compiling other software than swak with that installation? Because it seems that this is a problem with the installation, not swak. swak doesn't specify which MPI to use but uses the options that wmake automatically generates (have a look for instance at Utilities/replayTransientBC/Make/options - that is one of the links that is failing and it uses only standard-options).

What version of Linux are you using?

Thanks Bernhard,

the problem was indeed somewhere else. I was looking for it for a while with our admin, who takes care of the cluster. Finally, his conclusion was that the openmpi installed on the cluster was compiled with intel compiler while OF uses gcc. However, compiling ThirdPartys and src's caused no errors, these errors occurred only while compiling some application and swak4foam. After recompiling the openmpi with gcc, everything was ok.

Nevertheless, the warnings are still there. But since there are no errors, I think it's ok.

Thank you for the hints and best regards,
Ilya

groovyBC problems
 

Hi guys,


it's my first time using groovyBC and I'm trying to set up a parabolic profile of inlet velocity. What I'm doing is editing the U file to have the following code for inlet

and also I edited the controlDict file in system to include

But, when I run the case I get the following message

Anyone knows what I'm doing wrong?

Hi Bernhard,

I use openfoam/2.3.0 on a virtual machine (MASSIVE). I try to implement a zero flux condition via swaf4foam. I have swak4foam/2.3.0. I guess it is well installed as the answer to the command module show swak4foam/2.3.0

-------------------------------------------------------------------
/usr/local/Modules/modulefiles/swak4foam/2.3.0:

conflict swak4foam
module load openfoam/2.3.0

So the installation seems to be complete. When I try to set up the path of the plug-in

libs (
"libgroovyBC.so"
);

I have a FOAM:WARNING

in file db/dynamicLibrary/dlLibraryTable/dlLibraryTable.C at line 99
could not load "libgroovyBC.so"

The foam warning doesn't stop the program as this isn't a fatal error. But I need to use this groovyBC for my boundary condition. My boundary condition is:

upperWall
{
type groovyBC;
value uniform (0 0 0);
valueExpression "0.001*T-DT*fvc::snGrad(T)"
}

And as expected I now have a fatal error:

--> FOAM FATAL IO ERROR:
Unknown patchField type groovyBC for patch type patch

Valid patchField types are :.......


Do you have any idea how I can solve this problem? Why do I receive a foam warning for the .so file while swak4foam is apparently well installed.

groovyBC or codedfixedValue
 

Hello Foamers,

I want to implement a boundary condition at electrode.

N_P= K * Efield * N_P

I am solving following equation with modified pisoFoam.

(fvm::ddt(N_P)) + (fvm::div(phi+(K*Efield), N_P))

and for the electrode, I have to implent following BC, N_P = K * Efield * N_P.
so my BC condition will change with every time step.

In this equation N_P and Efield " need to be taken from electrode at previous time step and K is dimensionedScalar fix value 1.

Should I have to used codedfixed BC or some other BC? I have also trying groovyBC but I am failed.
is there anyone know how to implemrnt this BC?
Thanks in advance.
