Need Help About Post-Processing Ansys Fluent
 

Hello everyone, I got problem with ansys fluent post-processing. You can see in the picture I attached. Why the quality of temperature distribution is bad ? I mean look at near nozzle and left side of tube domain, why there isn't full blue temperature contour ? Is there something I miss ? or need some mesh improvement?. My mesh is safe based on the orthogonality and skewness (both min, max and average value)

[SOLVED]

In the plane section, I change the offset of "X" from zero to 4 mm
