Hello,
I have an Error from the Solver AcuSolver.

I try to solve a Thermical CFD simulation with a Heat Sorce, Inlet, Outlet and the Fluid Air (Bossinesq)

The Error Message from the Solver is: Error: problem does not have temperature_flow equation

I dont know where my mistake is. Could you help me. 

Best Regards,

Theo

    Go to setup > physics > solver controls and make sure temperature flow is tuned on.

    Is your inlet condition stagnation pressure or a very small velocity? The latter is preferable if you are trying to do a  steady state simulation.

    Hopefully the above answer solved your issue. If not, please upload your .inp and .Log file (they have no geometry information, so should be generally ok).
