hi DSpreitz,



In the end, I haven't installed the cgnsTools in ubuntu, because it is used only for display cgns files and it'is difficult to installed it;
for the geometry cgns we are using NUMECA IGG Software in our laboratory, and I use Paraview to see the outcome of the conversion,
I think you needn't install adfviewer.

hope it help you.

hi everybody,

Maybe this info is useful for people dealing with 2D Meshes.
I converted a 2D Mesh and after the conversion the mesh is extruded in z-direction, which is ok as Openfoam doesnt work with "real" 2D meshes. But the extrusion is much too high as it is set automatically to 1. This causes cells with a high aspect ratio, which leads to strange results. I solved the problem by modifying the point file manually and then using checkMesh to check if the mesh is ok with the reduced extrusion. Maybe somebody has a better and more comfortable idea?

Alex

Hi Martin,

nice work with the cgns converter! Did you consider to add a cgns output to the simplefunctionObjects for writing patch/planes during the simulation as well? This would be great :-)

Best Regards!

hello,*
I tried to install cgns converter in OF-1.6 but without success using the web page:
http://openfoamwiki.net/index.ph/Sig...GNS_Converters
is there a solution for this?

thanks in advance.

[mbeaudoin]

Hello,

Our group has developed and contributed the source code for the CGNS converters.

We are not using version 1.6 yet, so basically we have not contributed any adjustments to the CGNS converters source code for that release.

One solution for you is to keep on working on the source code in order to make it run. That's the beauty of the Open Source concept.

Regards,

Martin

Hello,
I'm actually implementing some functions writing in CGNS format from OpenFoam in order to have identical file structure than the files used as input in VLab (Acoustic BEM solver)...

To do so, I have to write informations about "time step" or "actual time"... This is done using :

CGNSOO::BaseIterativeData_t Base_it = cgnsBase.writeBaseIterativeData( "TimeIterValues", nsteps );
Base_it.writeDataArray("TimeValues", time );
Base_it.writeDataArray("IterationValues", it );

I have the following error when I'm running my function :
terminate called after throwing an instance of 'CGNSOO::cgns_exception'
what(): CGNS error in node::go_here while calling cg_goto
can't go to label 'ZoneIterativeData_t' under 'CGNSBase_t'
Aborted

To solve the problem, I changed in the file base.C of the libcgnsoo librairies the following line in the last function (BaseIterativeData_t Base_t::writeBaseIterativeData( const string& name, int nsteps )) :

return BaseIterativeData_t(push("ZoneIterativeData_t",1)) ;
to :
return BaseIterativeData_t(push("BaseIterativeData_t",1)) ;

Is it a bug in the librairies? or am I using the functions in a wrong way and this was not a bug??

If it's not a bug, how to do :

cg_biter_write(index_file,index_base,"TimeIterValu es",nsteps);
cg_goto(index_file,index_base,"BaseIterativeData_t ",1,"end");
cg_array_write("TimeValues",RealDouble,1,&nb,&time );
cg_array_write("IterationValues",Integer,1,&nb,&it );

using the functions of the libcgnsoo??

Thank you in advance for you answer,
Julien

[rmagnan]

You're right Julien,

It is definitely a bug and your solution looks right. This is one area of libcgnsoo that was never used nor tested...

Are you calling this from within cgnsToFoam or are you calling the library from your own code?

-Robert

[christju]

I'm using it in my own code... that is in fact quite similar to the foamToCGNS utility. I just simplify it because I just need the surface pressure on the walls but also some extra informations like the face areas and the face normals...

Thank you for the answer

Julien

[christju]

I have an other problem concerning the element type....
I have a mesh that I created myself, so I know there are only HEXA_8 elements. But using the foamToCGNS function, I have always MIXED type....
I think there is a problem in the writeCGNS.H function when the element type is checked on all the cells. A loop is done on the cells :

bool first_time = true;;
forAll(cells, celli)
{
int nVerticesFirstCell = 0;
if( first_time )
{
first_time = false;
nVerticesFirstCell = cells[celli].size(); // Type of first cell

// check the type of the first cell (I remove the code for this post)

}
else if(nVerticesFirstCell != cells[celli].size()) // Is the next one different
{
element_type = CGNSOO::MIXED;
s_element_type = "MIXED";
break;
}
}

The nVerticicesFirstCell variable is (re)set to zero in the cell loop... so the elseif is always true and then the element type is always MIXED....
I think the " int nVerticesFirstCell = 0;" should be out of the cell loop right?

I hope it helps,
Julien

The first problem apparently is the function db (). Probably defined differently than in OF1.5. Maybe someone can give me a hint. Or tell me what function db () is and where it is defined.

I would be grateful for any help.

Hey, I got the cgnsToFoam converter to work with OpenFOAM 1.6.x and ubuntu 9.10. First of all, to compile the libs I had to install libtools from the repository. Then I needed to make a minor change to the code to get cgnsToFoam to work (see below). I have to admit I don't really know what I'm doing, but since the Xfer object just seems to be there for transfer purposes I thought the damage I could do is small, and it seems to work as the cgnsToFoam test case ran without errors. I'll see if I can get foamToCGNS to work with 1.6 as well.

In file CGNSBoundaryConditions.C:

Foam::polyMesh* CGNSBoundaryConditions::buildFoamMesh( const Foam::Time& t ) const
{
    //int n = patchFaces.size();
    if ( debug_ )
    {
        Foam::Info << "Patches:\n";
        forAll( patchNames, i )
        {
            Foam::Info << "\tPatch " << i << " named " << patchNames[i] 
                << ", type = " << patchTypes[i] << "/" << patchPhysicalTypes[i] 
                << Foam::endl;
        }
    }
    Foam::word defaultPatchName = "defaultWall";
    Foam::word defaultPatchType = Foam::wallPolyPatch::typeName;
    return new Foam::polyMesh(
        Foam::IOobject
        (
            Foam::polyMesh::defaultRegion,
            t.constant(),
            t
        ),
        Foam::Xfer<Foam::Field<Foam::Vector<double> > >(mapper.getPoints()),
        mapper.getCells(),
        patchFaces,
        patchNames,
        patchTypes,
        defaultPatchName,
        defaultPatchType,
        patchPhysicalTypes,
        true
    );
}

I just got it to work. The answer is right there, but I missed it myself for quite a while! Edit the Allwmake file to include settings for TKINCS:

make TKLIBS="-L/usr/lib64 -ltcl8.4 -ltk8.4" TKOGLXLIB="-L/usr/X11R6/lib64 -lXmu -lXext" TKINCS="-I/usr/include/tcl"

[akidess]

Ok, so to make foamToCGNS compatible with 1.6, first the make options have to be modified to account for the new directory structure:
-I$(WM_PROJECT_DIR)/src/turbulenceModels/incompressible/RAS/lnInclude

(incompressible and RAS switched positions).

Then, in file foamToCGNS.C, line 161:
volPointInterpolation pInterp(mesh);

In 1.6, volPointInterpolation just takes one argument, an fvMesh. So it looks like we don't need to make a pointMesh any more. I used the test2 test-case and had a look at the resulting .cgns file with the cgnstools, and it seems to be alright. Of course it would be better if someone had a look at it in a proper post-processing tool as I was just looking for absolutely obvious misbehavior.

[hamcer]

hi! akidess,

I m still under OF-1.5 to use cgnsToFoam, but I w'd like use't under OF-1.6 also.
Hence I do the modifications what you have done but, without suces:
My system is ubuntu-9.10 32 bit:
since I use 32 bit I made modification in Allwmake as follow:

make TKLIBS="-L/usr/lib -ltcl8.4 -ltk8.4" TKOGLXLIB="-L/usr/X11R6/lib -lXmu -lXext"TKINCS="-I/usr/include/tcl"
and i done your line
make TKLIBS="-L/usr/lib64 -ltcl8.4 -ltk8.4" TKOGLXLIB="-L/usr/X11R6/lib64 -lXmu -lXext"TKINCS="-I/usr/include/tcl"
and for both lignes i have:
cgnsToFoam : commande not found

[akidess]

Hamdi, you are not giving me a lot to work with here.. Were you able to compile the converters? Were there any errors when you executed the make-command? If not, the problem might be that the utility binaries are not in your $PATH.

[hamcer]

hello akidess ;

Hi

Am having the following error when running ./Allwmake in src:

cgnsoo.H:383: error: ‘range’ is not a type

OpenFoamTurbo compiles as does cgnslib...

Any solutions?

Thanks
