Regenerator is on a distinguished road
Dear all,

I am a quite new FLUENT user and I am having some problems in a "simple" heat transfer model.
The problem is a duct where the air is heated by two small hot surfaces (the boundary in this surface could be a fix temperature or a heat flux) in any case after finished the run and the residuals are lower than 1e-7 the energy balance is no zero.
I am checking in report/fluxes.
Coudl you help me to check my model?
Another questions about the mesh, in another model I have some cell where the temperature reach the limit, is there any tool to "delete" or not consedered bad quality cells in the calculations?
Thanks in advance
