Reply To: High temperature gas flow in a furnace at underpressure (p<1 atm)

[Yves Feisel]

So, is there really no other way to simulate the gas flow at the desired conditions (high temperature/underpressure)?

I saw that I can set the overall pressure when simulating ideal gases. This would actually be my preferred way of handling this topic, but in this case I cannot set a defined mass flow as the inflow condition. But this is essential for me as in the real case that I am trying to simulate, we can precisely define the amount of gas going into the furnace, but the pressure at the inlet may slightly fluctuate and is dependent on other variables as well. 

However, trial runs setting input/output/overall pressures never lead to a result anyway. Discovery would always stop solving after some seconds without an apparent reason. 

Any further ideas would be highly appreciated. Simulating this scenario is basically the reason why we bought the licence.
