Hi, Dear FOAMers !

I encountered a problem when compiling my new solver.
For this solver, I implemented a library libdugksFoam.so contains a numerical model fvDVM and several new B.C.s .

The compilation of the the library is OK.
But when the solver dugksFoam link to the library, there is an error saying :

undefined reference to`Foam::calculatedMaxwellFvPatchField<double>::typeName'.

The calculatedMaxwellFvPatchField is one of the new BC in the libarary.

The detailed compilation output is :

BTW, my OF version is 2.2.x .

Hopefully someone can shed some light on this question. Thanks!

I found it was the following code piece in the the discreteVelocity.C caused the problem.

But I still don't know why.

The new calculatedMaxwellFvPatchField is copied and changed from the fixedGradientFvPatchField.
I just changed the gradient_ member to the outGoing_ member.

516         {
517             calculatedMaxwellFvPatchField<scalar>& rhoPatch =
518                 refCast<calculatedMaxwellFvPatchField<scalar> >
519                 (dvm_.rhoVol().boundaryField()[patchi]);
520
521             forAll(gSurfPatch, facei)
522             {
523                 vector faceSf= SfPatch[facei];
524                 if ((xii & faceSf) >  0 ) // outgoing
525                 {
526                     gSurfPatch[facei] = iGbarPvol[faceCells[facei]]
527                         + ((iGbarPgrad[faceCells[facei]])
528                         & (CfPatch[facei] - C[faceCells[facei]] - xii*dt));
529                     hSurfPatch[facei] = iHbarPvol[faceCells[facei]]
530                         + ((iHbarPgrad[faceCells[facei]])
531                         & (CfPatch[facei] - C[faceCells[facei]] - xii*dt));
532                     rhoPatch.outGoing()[facei] //add to outGoing container
533                         += weight_ * (xii & faceSf) * gSurfPatch[facei];
534                 }
535             }
536         }

Hope this information will help you guys to figure out what's going wrong.

Hah! Finally, I figured out what's going wrong.


It's because I first compiled the new boundary conditions BCs into the library libdugksFoam,
then compile the fvDVM into the same library libdugksFoam,
but the fvDVM uses the definitions in BCs.

I solved the problem by compiled the BCs into a anther library libdugksFoamBC,
and let fvDVM uses this library and compiled into libdugksFoam.
At last, let my new solver use these two libraries.

Hey...How did u solve this error ?? I am strucking to the similar kind of error....Please see followiing image....Screenshot from 2018-07-15 10:44:47.jpg

[ruchit@15847]

Yaaah....Finally got it whats wrong going on !!! Actually I modified options file partially. So that's the problem. So I modified it completely and it compile correctly.

I too am facing this problem, what was the partial edit of options causing this?

I too faced a similar problem a year ago, I just can't figure out how I solved it. I am creating a new "type" in openfoam.

this generally happens when your older links of functions and types are there in the old .so file,

better delete old .so files and recompile
