Thanks for the report. The issue is that some places in OpenLB use non-standard runtime-defined C-style array sizes which do not work in all compilers. This will be fixed in the next release, until then you can replace lines 85 and 86 in src/functors/lattice/timeAveraged/superLatticeTimeAveraged3D.hh by e.g.:


      std::vector<BaseType<T>> tmp(_sFunctor.getTargetDim(), 0);
      _sFunctor(tmp.data(), i);
