Hey Markus and lbTeam,

Thank you a lot.

bstep2d.cpp calls UnitConverter<T, DESCRPITOR>, however, unitConverter.cpp does contain the only D2Q9Descriptor for 2D as the following:

Code:
template class UnitConverter<double,descriptors::D2Q9Descriptor>;
template class UnitConverter<double,descriptors::D3Q19Descriptor>;
template class UnitConverter<double,descriptors::AdvectionDiffusionD3Q7Descriptor>;

template UnitConverter<double,descriptors::D2Q9Descriptor>* createUnitConverter(const olb::XMLreader&);

I would like to know what happens when we use

Code:
#define DESCRIPTOR D2Q9_M_Descriptor

in bstep2d.cpp.

Also in firstOrderLbHelpers2d.h, there exists only “descriptors::D2Q9Descriptor”.

Best,
Chris
