Rolo is on a distinguished road
I am trying of simulate a furnace under flameless conditions, I use EDC model with species transport, k-epsilon standard and OD for radiation. However the residuals of energy and radiation, does not drop to 1e-6. The residuals only drop to 1e-5 for energy and radiation and to 1e-3 for continuity.

What I can do to improve the convergence?
