 August 6, 2008, 20:25 steady simulation #1 Rogerio Fernandes Brito Guest   Posts: n/a Is it possible to do a steady simulation for a specified physical time, for example, 30 seconds?

 August 7, 2008, 02:04 Re: steady simulation #2 Toralf Guest   Posts: n/a I have learned: steady state = time-independent and transient = time-dependent. So the answer is NO. Of course it is possible that I have not understand your question.

 August 9, 2008, 16:47 Re: steady simulation #4 Rogerio Fernandes Brito Guest   Posts: n/a I mean that: I would like to simulate a case, cavity with laminar natural convection, with 30 seconds (this number, it´s just an example, ok?), but for a physical time. I don´t want to analyse my problem after it arrived to steady state*. (supposing that it* takes 90 seconds, for example). Is it possible to set up it on CFX-Pre using a steady state simulation?

 August 9, 2008, 20:22 Re: steady simulation #6 Rogerio Fernandes Brito Guest   Posts: n/a I was simulating 2 types of regimes: With transient, i have the maximum and the minimum, respectively, 29 ºC and 5 ºC. With steady state simulation, i have the maximum and the minimum, respectively, 18 ºC and 5 ºC.
