non engine application in KIVA
 

Hello everybody, I am using KIVA for a non-engine application. When I define the piston aa a solid boundary so that it doesnt move there is no temperature convection taking place into the cell. I am using 400K of piston temperature and 290K for other walls. But there is no temperature convection taking place into the cell. Can anyone help me with this. Thanks in advance.
