Hi Foamers

I tried to develop a new library, but some strange linking errors appeared:

/platformsnux64GccDPInt64OptbbPBE.so: undefined reference to `Foam::messageStream::masterStream(int)'
/platformsnux64GccDPInt64OptbbPBE.so: undefined reference to `Foam::reduce(double&, Foam::minOp<double> const&, int, int)'
/platformsnux64GccDPInt64OptbbPBE.so: undefined reference to `Foam::HashTableCore::canonicalSize(int)'
/platformsnux64GccDPInt64OptbbPBE.so: undefined reference to `Foam::PstreamBuffers::PstreamBuffers(Foam::UPstre am::commsTypes, int, int, Foam::IOstream::streamFormat, Foam::IOstream::versionNumber)'
/platformsnux64GccDPInt64OptbbPBE.so: undefined reference to `Foam::reduce(double&, Foam::sumOp<double> const&, int, int)'
/platformsnux64GccDPInt64OptbbPBE.so: undefined reference to `Foam::UIPstream::read(Foam::UPstream::commsTypes, int, char*, long, int, int)'

platformsnux64GccDPInt64OptbbPBE.so: undefined reference to `Foam::UOPstream::write(Foam::UPstream::commsTypes , int, char const*, long, int, int)'
collect2: error: ld returned 1 exit status

I am exhausted.
I really appreciate your input and help.

I am afraid, it is not easy for anyone here to help you without giving more details about your code. The problem is basically linking issue or problem with your OpenFOAM installation.

Hi Hassan,

Glad to have you here.
Basically, I was trying to use a PBE solver that was released at Github:
https://github.com/robertsawko/OpenPBE

These errors happend when I was installing (compiling and linking) it.
I have trying hard to solve it, but still failed.
I was curious what kind of reasons lead to the errors.
I reported the errors to the developer, but got no responses yet.
Could you please have a look at your convenience and give some help?

Best regards,

[hk318i]

Hello,

I installed on my machine and I run the validation case using ``PBEFoam``. It worked fine. When exactly does this error appear?

Hello Hassan,

I have posted my compiling and linking processes at:

https://github.com/robertsawko/OpenPBE/issues/18

Could you take a look and see if you can find my origin of errors?

By the way, could you please share your installing steps?

Really appreciate!

Best regards,

Hi
i hun interFoam solver and i have this result and stay going like this doesnt converge if some one know why

Phase-1 volume fraction = 1.2403e-06 Min(alpha1) = 0 Max(alpha1) =1 ,,,,,
Phase-1 volume fraction = 2.62429e-06 Min(alpha1) = 0 Max(alpha1) = 1
Phase-1 volume fraction = 4.17437e-06 Min(alpha1) = 0 Max(alpha1) = 1
Phase-1 volume fraction = 4.17437e-06 Min(alpha1) = -3.41753e-06 Max(alpha1) = 1

Phase-1 volume fraction = 5.87017e-06 Min(alpha1) = -2.97194e-06 Max(alpha1) = 1

Phase-1 volume fraction = 5.87016e-06 Min(alpha1) = -4.20485e-06 Max(alpha1) = 1

Phase-1 volume fraction = 7.58627e-06 Min(alpha1) = -3.92262e-06 Max(alpha1) = 1

Phase-1 volume fraction = 7.58627e-06 Min(alpha1) = -0.000100555 Max(alpha1) = 1

Best regards,

I followed the same steps as you did. I think this error could be a problem in your OpenFOAM installation not in OpenPBE. Have you tried to remove it and reinstall? or at least have you tried to recompile OF?

I think this section of the forum is not suitable for your question. You will have to give more details about your case because the convergence depends on many parameters. No one can really help you based on these few lines.

Hello Hassan

Yes, I have recompiled the openfoam. But still failed...
Could you mind telling me which verion of OF do you use?
I have three versions of OF installed on my machine (don't know if this spoils).
The OS of my computer is Ubuntu LTS 16.04.


Best regards,

[hk318i]

I tested it on Ubuntu 14.04LTS and OpenFOAM-3.0 (pre-compiled version). There is no problem to have multiply versions of OF if your are sourcing the right version. Apart from OpenPBE, is your installation working fine?

[doubledang]

My openfoam installation works fine for all the other applications.
What do you mean by "pre-compiled" version?
Do you mean it is unpacked OF source code folder?
The problem struggled me over almost 2 weeks.
I really exhausted.

Do you have any ideas or suggestions as to work around the problem
in my case?

Really Appreciate your input!

[anishtain4]

In the github you provided it seems OF version 3.0 is needed. OpenFOAM had some fundamental changes in some of the version and most of the utilities will not be compatible if you use the wrong generation of OF.
Also you need Eigen 3 but the errors seem to be from OF.

I mean Ubuntu version, I didn't compile OF-3 on this particular machine form the source files, {LINK}
Based on your report in Github, you managed to install all the prerequisites successfully, that is why I though it is maybe related to OF installation.

Hello , Yes exactly, I also installed it successfully on my labtop this morning.
I have OF3.0.1 on my laptop.
So, I feel strange why it fails on my workstation.
Do you have any suggestions to get the reasons why it sucks on my workstation?

Best regards,

[hk318i]

Maybe it is related to Ubuntu 16.04 LTS, because I think pre-compiled OF-3 does not support Ubuntu 16.04

Thanks Hassan for your help!

I came to agree with you that is is possibly casued by Ubuntu sys.
By the way, could you hint how to run the validation case?
I have just install PyFoam.
But I have no idea as to how to use pyFoam.


Best regards,

[hk318i]

There is a code called setupCass.py in galinat just run it. This code creates few cases and it uses pyFoam

Yes, i have run the setupCases.py file, then some cases are established.
How could i run the cases such as re6400NC10 re6400NC20 ...
I tried to use pyFoamRunner.py, but failed.
Do I need to write pyFoam script to run them?


Thanks!

Best regards,

[hk318i]

I run blockMesh then the solver as any OpenFOAM case. Personally, I don't use pyFoam

Okay, thanks, Hassan
