Hello there,

I'm finding poor convergence when I include The thermal Energy equation in my model of the ventilation of a hospital room.
Under ISOTHERMAL conditions the simulation converges well otherwise with the UDS but not under High Resolutions schemes. Seems to quite common but why?

Thanks for some advice
