In the shell, the boundary conditions are also given, and with temprature and velocity inlet i perform that but The problem is that in the first circuit and second circuit pressure are given in mega-pascal and different values ​​of 7.4 and 15.3, and I do not know how to enter these values ​​. I also send the picture of boundry condition.
