Hi Jonathan,
Thanks for the reply. I feel kind of silly now haha. I’ve thought my results were incorrect.
Cheers,
Vinhvinhvu1995ParticipantHey Marc,
Sorry for that mistake! I have no idea how I managed to do that. Everything is working fine now! I’m currently running a few test cases with the wall function boundary on and everything seems to work fine. For some reason, the simulation diverges whenever I use a MPI but I think I can work out what’s causing the problem.
Cheers,
Vinhvinhvu1995ParticipantHi Marc,
Thanks for the reply, I’ve replaced the erroneous line and I still cannot compile my code. This is the error I get
src/boundary/wallFunctionBoundaryPostProcessors3D.hh: In member function ‘void olb::WallFunctionBoundaryProcessor3D<T, DESCRIPTOR>::computeFneqRNEBB(olb::Cell<T, DESCRIPTOR>&, T*, T, T*)’: /src/boundary/wallFunctionBoundaryPostProcessors3D.hh:711:96: error: no matching function for call to ‘opposite(__gnu_cxx::__alloc_traits<std::allocator<int>, int>::value_type&)’ 711 | fneq_bc[normalInwardsIndices[fIndex]] = fneq_bc[util::opposite(normalInwardsIndices[fIndex])]; | ^ In file included src/dynamics/dynamics.h:32, /src/boundary/boundaryCondition3D.h:31, src/boundary/boundary3D.h:28, src/olb3D.h:1, from array.cpp:7: src/core/util.h:193:47: note: candidate: ‘template<class DESCRIPTORBASE> int olb::util::opposite(int)’ 193 | template <typename DESCRIPTORBASE> inline int opposite(int iPop) | ^~~~~~~~ src/core/util.h:193:47: note: template argument deduction/substitution failed: In file included from src/boundary/boundary3D.hh:42, from src/olb3D.hh:1, from array.cpp:9: src/boundary/wallFunctionBoundaryPostProcessors3D.hh:711:96: note: couldn’t deduce template parameter ‘DESCRIPTORBASE’ 711 | fneq_bc[normalInwardsIndices[fIndex]] = fneq_bc[util::opposite(normalInwardsIndices[fIndex])]; |
I guess the next release has the updated code which should fix the problems. Do you think it be better if I waited for the next release?

vinhvu1995ParticipantHi Marc,
Thanks for the summary, it did help me a lot. I think I nearly got it all working now, but I’m having an issue with the WallFunctionForcedD3Q19Descriptor. For some reason I can’t compile my code with that specific descriptor. I get the following error
error: ‘opposite’ is not a member of ‘olb::descriptors::D3Q19<olb::descriptors::AV_SHEAR, olb::descriptors::TAU_W, olb::descriptors::TAU_EFF, olb::descriptors::FORCE, olb::descriptors::V12>’
If I chose a different descriptor (say D3Q19), then it compiles fine, but it will produce a segmentation error, presumably because the wall function boundary is not working properly without the proper descriptor. Is there something I’m missing with the wall function descriptor?
Cheers,
