Hello everyone!
I'm trying to postProcess a case by using linear and surface sampling and I recieved wrong results of temperature, the temperature is equal to 193K in whole domain, while the other quantities seemes to be fine. I checked the time/T results itself and numbers there are fine, paraview does not have any troubles with opening it.



Functions inside controlDict

Code:

I uploaded exemplary results, unfortunately I can't upload the T results itself because the file is to big.

If anyone had the same problem or know the solution please let me know.
Thank you all in advance!
