I am trying to develop a gas netwrok in which I am trying to control the flow of gas in the netwrok with the help of temperature control valve .
There's two things I am facing ,
1)There is no flow established in the newtork around the valve though I have add mass flow rate block in the system
2)Temperature control valve is not control the flow of the gas in the network even after defining the actuation temperature .
I am attaching my model with this.
Please help me out in this matter asap
Waiting for response.
