naruto5255 New Member goku Join Date: Jun 2015 Posts: 12 Rep Power: 11	I am working on HVAC.A 3d room with 3 inlet window and 3 outlet window in opposite direction.Inlet velocity is 0.1m/s. outlet is pressure bounday condition. The turbulence model used is K EPSILON. Heat flux from floor is 10w/m2. when i solve the (flow & turbulence )and energy equation separately the solution is converged.But when i solve the equation together the energy equation is not converging. It shows the error Divergence detected in the AMG solver: temperature. Error object :#f. Pressure based solver, gravity is switched off..
