Reply To: Using addWallFunctionBoundary

Hi 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*)’:

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?

Cheers,
Vinh
