Hi to everybody

I am trying to write a modified version of the interstitialInletVelocity BC with to ad the possibility to specify both space and time dependence of a velocity inlet boundary condition.
I have more or less managed to do that (in order to have the subroutine compile I have to disable the evaluation of the time dependence from the subroutine itself by commenting out

    /* fixedValueFvPatchVectorField::operator==(profilemult_->value(dirCmpt)); */

in the Member function part of the code otherwise it won't compile, If you have comments on the subroutine itself feel free to post them ) since for I can live without the time dependence but not the variation with space of the inlet velocity.
When I try to execute setField for example I have the following error message:

--> FOAM Warning : 
    From function void* Foam::dlOpen(const Foam::fileName&, bool)
    in file POSIX.C at line 1037
    dlopen error : /home/luca/OpenFOAM/luca-4.1/platforms/linux64GccDPInt32Opt/lib/libtimespacevarinterstitialInletVelocityBC.so: undefined symbol: _ZTVN4Foam55timespacevarinterstitialInletVelocityFvPatchVectorFieldE
--> FOAM Warning : 
    From function bool Foam::dlLibraryTable::open(const Foam::fileName&, bool)
    in file db/dynamicLibrary/dlLibraryTable/dlLibraryTable.C at line 97
    could not load "libtimespacevarinterstitialInletVelocityBC.so"

If anyone can give me some help I would be grateful. I am quite new at OF programming and my knowledge of C++ is quite limited.
I am currently using OF 4.1

Thank you in advance.

Hi Luca,


I'm experiencing the same problem you had here and I can't manage to find where the error could be. Did you solve your problem?


Best Regards,

I opted for a different approach and dropped my attempt at the subroutine

Sorry

Ok no problem, I think that i mispelled something and could not find where because the file was too long, I started again from the beginning and after the linking had not problem.
