Hi Johanna,
The compilation is OK, but the simulation diverges directly.
I posted the main program and the temperature NeumannBC I wrote on GitLab. Would you mind help checking where the problem is?

This is an LES + Boussinesq approximation simulation of the convective heat transfer problem.
The invocation of NeumannBC is in lines 512-529 of CesT.cpp, and neumannBC is implemented in AdvectionDiffusionNeumannBoundaryProcessor3D.h.

Thank you.
with best wishes,
