Hello,
got a little problem. I try to simulate an heatexchanger. Because of my model is to big(61Tubes) i have to waiver of the innerflow. My question is, how to define a Temperature function for the wall of a tube. The function is quite simple: T(x)=T0 - 20*x/618 T0=343.15K L(length of the tube)= 618mm x is the coordinate of the length, so that at the beginning i got an value of 343.15K and at the end 323.15K for the temperature. big thanks for help |

Use an UDF in which you can define the temperature as a boundary condition.
