I am using a temperature profile to add to my simulation. As can be seen in the picture, the initial wall temperature looks good after implementing the profile. Now after a few iterations, the temperature already changes (picture 2). I know this can be due to conduction of the flow ( I think ), but how do I change this? I want to keep the wall temperature constant as it is in the profile.

initial wall temperature:

after some iterations:

 

the profile also perfectly fits the vial wall:

Does this have something to do with the 'profile update interval' in the 'run calculation' tab?

Hi,

Profile Update Interval: sets the number of iterations that will pass before user-defined functions for boundary profiles will be updated. This interval also controls the frequency at which named expression values will be updated.

Check if you have tick the boundary value while plotting the contour
