Hi, when I was processing data in CFD-POST, I found that the minimum temperatures obtained using two methods on the same location were different. A minimum temperature is obtained in the contour plot, T_min1=2.58 K, shown in fig.1. Another minimum temperature is obtained in the function calculator, T_min2=1.96 K, shown in fig.2. what's the difference between the two minimum values? and which one should I choose as the minimum value? please give me some advice, thanks a lot.
