set the pressure on a whole subdomain
Hi. It's the first time I am working on CFX. I am using CFX 5.7.1 I want to set the value of the pressure and the temperature on a whole subdomain. These value are in .csv file How can I make to do that? The main problem for me, is: how to set the pressure and the temperature on a subdomain?
Re: set the pressure on a whole subdomain
You can add a source term and source coefficient to the energy equation in the subdomain to maintain a fixed temperature. For example, use the follow expressions:
Scoeff = -1000000 [W m^-3 K^-1]
Sterm = Scoeff * (T - 325 [K])
END END END
Scoeff is just any big number; the bigger it gets, the stronger the correction source will become.
Pressure is part of the solution and there is no such thing as a pressure source term, so you cannot control pressure in a similar way. Mike
