Hello,
in the past, I was able to install and run ccm26ToFoam on OF.org/v8 but I don't succeed to repeat this on OF.com/2112, whether with ccmToFoam or 'local' ccm26ToFoam.

.about ccmToFoam which comes already installed within the OF folder:
Doing

./Allwmake

in the src/conversion/ccm folder gives :

==> skip ccmio (no header)
==> skip optional libccm adapter

is there something missing ? what could be the issue ?




.about ccm26ToFoam which comes from:

https://github.com/wyldckat/localCCM26ToFOAM

Doing

ccm26ToFoam -help

gives :

ccm26ToFoam: symbol lookup error: ccm26ToFoam: undefined symbol: _ZNK4Foam11regIOobject11writeObjectENS_8IOstream12streamFormatENS1_13versionNumberENS1_15compressionTypeEb

again, what could be the issue here ?



many thanks in advance for any help

Hi Alex,



I abandoned OpenFOAM for a while now, but if I remember correctly these errors are related to the fact that the libraries used to convert the mesh to/from StarCCM are propretary and thus are not shipped with OpenFOAM.


You should look online for the ccmio and libccm libraries and download them separately, then re-build the application.


Where you can find these libs? No idea, if I remember correctly I found them inside a github project somewhere.



Good luck!

Hello,

what are the steps to follow for ccmToFoam with OF2112 as there is no ThirdParty directory?

thanks

Unfortunately I don't recall it.. But from the version name it looks like you're using the OpenCFD version of openfoam. This is a little bit different from the OpenFOAM Fundation version (OpenFOAM v9). You might want to try and install this latter version and see if you find what you're looking for.. https://openfoam.org/version/9/


The procedure I followed is more or less this: I went and built the ccm2foam application using its wmake script. You can probably find a procedure here:

[OpenFOAM-v1706] ccmToFoam error
The issue is that at some point you don't have the libbccmio library, which is propretary. Try looking into github: https://github.com/MVoz/libccmio-msv...aster/libccmio
This is probably where I found the libccmio library. I take no responsability for the content of the download tho, since I don't recall if this is exactly the one I downloaded.



The procedure then would be: build the shared library libccmio.so, then building the application ccm2foam, including the .so in the wmake file so that the compiler uses it.



I hope this was helpful.

Hello all. Here is how you can build the ccmToFoam utility with OpenFoam-v2212 from www.openfoam.com. I am on Linux/Ubuntu.

1. Download the source code for openfoam-v2212.tgz and thirdparty-v2212.tgz from https://dl.openfoam.com/source/latest/
2. Unzip both files in your openfoam install location, e.g. ~/openfoam/. The two folders should be parallel. You don't need to move the thirdparty-v2212 folder inside openfoam-v2212.
3. Download the libccmio library. I found a download link by going into ThirdParty-v2212 and running "./makeCCMIO -help"
4. Copy the libccmio top level folder into the ThirdParty-v2212 folder. My directory reads openfoam/ThirdParty-v2212/libccmio-2.6.1.
5. Go into /OpenFOAM-v2212 and run "source etc/bashrc" to make sure your environment is set up.
6. Go into /OpenFOAM-v2212 and run "./Allwmake". This will take a while.
7. Go into /ThirdParty-v2212 and run "./makeCCMIO" and "./makeCCMIO lib". You should now have folders "include" and "lib" in openfoam/ThirdParty-v2212/platforms/linux64Gcc/libccmio-2.6.1/
8. Go into /OpenFOAM-v2212/src/conversion/ccm and run "./Allwmake"
9. Finally, go into OpenFOAM-v2212/applications/utilities/mesh/conversion/ccm and run "./Allwmake"
10. You should now have the ccmToFoam executable. For me, it's located in OpenFOAM-v2212/platforms/linux64GccDPInt32Opt/bin/ccmToFoam

Thanks Nick for sharing this information

Hello all, I followed the instructions from Nick to build utility ccmToFoam with OpenFOAM-v2306 on OpenSUSE OS (cross-compiled).

But I faced the problem that undefine references such as:
../OpenFOAM-v2306/build/linux64MingwDPInt32Opt/applications/utilities/mesh/conversion/ccm/ccmToFoam/ccmToFoam.o:ccmToFoam.C.text.startup+0x7c4): undefined reference to `Foam::ccm::reader::reader(Foam::fileName const&, Foam::ccm::reader:ptions const&)

Do you have any ideas to resolved this problem? Thank you in advance.
