Hi all,

I have been trying to get the laserConvectionBC to work however, the following error occurs every time I'm running it.

I am using Open FoAM v2006 running icoReactingInterFoAM solver.

I have added libs ("liblaserConvectionBC.so"); to controlDict.

I tried running it outside OpenfoAM folder and inside the tutorial (Multiphase) folders but the error is always the same as shown below.

--> FOAM Warning :
From void* Foam::dlLibraryTable:penLibrary(const Foam::fileName&, bool)
in file db/dynamicLibrary/dlLibraryTable/dlLibraryTable.C at line 65
Could not load "liblaserConvectionBC.so"
liblaserConvectionBC.so: cannot open shared object file: No such file or directory
Create mesh for time = 0

I have done wmake libso once following this instruction: https://bitbucket.org/shor-ty/laserc...bc/src/master/

Hopefully its not a big issue, I am considering the need to do this:
Using the BC within a special solver (not compiled as a stand alone library, offers more coupling but is only valid for this solver)
For that go to the following file
laserConvectionFvPatchField.H
Uncomment the last lines that are commented
// Only needed if you compile with your solver
#ifdef NoRepository
# include "laserConvectionFvPatchField.C"
#endif

But Im not sure how to execute this portion
"Go to the solver that you want to couple with the boundary condition
Add the boundary source file to your solver by adding the source file (and path) to the 'Make/files' file of your solver. It should look somehow like that (the first and last character is just for highlighting and should not be in the file):
'../../fvPatchFields/laserConvectionBC/laserConvectionFvPatchFields.C'
../../fvPatchFields/AOPCTractionDisplacement/AOPCTractionDisplacementFvPatchVectorField.C
../../fvPatchFields/fixedDisplacement/fixedDisplacementFvPatchVectorField.C
AOPCHeatTreatmentFoam.C

EXE = $(FOAM_USER_APPBIN)/AOPCHeatTreatmentFoam
Compile your solver
Done"

Did anyone experienced this? please help me

I just tried this extension on OFv2006 doesnt work and gives the following error when using wmake libso according to this link: https://bitbucket.org/shor-ty/laserc...bc/src/master/

And many more errors mainly from no matching function for call to the following:
‘Foam::List<Foam::Vector<double> >::append(Foam::ITstream&)’

no match for ‘operator=’ (operand types are ‘Foam::Vector<double>’ and ‘Foam::ITstream’) motionCenters_[nSources_-1] =

OFv1912 works fine.

Dear Mr. Toby,

I am building pulse laser welding model. Could you please show me how to apply heat flux model to tackle this case.
Thank you!

Any idea how I can tell the laser beam radius from the Temperature file? Im thinking SigmaX and SigmaY is the only way to control the laser beam radius, but looking through the guide from Tobi's laserConvectionBc, I still have not much clue to it.

Yes, you are right SigmaX and SigmaY is about laser dot radius.

Also I had made test case, which worked on old OpenFOAM v. 4.0, at least 2 years ago. Maybe will be helpful
