For the resolution of 40 you can try the following setup of the channel example:

const T latticeWallDistance = 0.5;  // lattice distance to boundary
const int rhoMethod = 1;    // method for density reconstruction
const int fneqMethod = 1;   // method for fneq reconstruction
const int wallProfile = 0;    // wallfunction profile

and for the converter you can use relaxation time of 0.50025 and Smagorinsky constant of 0.18. In that case it should be stable and more correct.

If you have interest to cooperate in terms of wall model in LBM please write on info@openlb.net
Best regards
