My udf comprises of Specific heat, Adiabatic temperature and Source term. I compiled it and ran it for two cycles (each cycle consists of 4.2 seconds). In the second cycle, I got some unexpected contour (figure 1).


So I again ran another simulation but this time I manually on and off the source term (Cell Zone Conditions-Solid-Source terms-on & off), here I got good results in the second cycle (figure 2).


Can anyone suggest me where I am doing wrong?

Note: I used the same udf and it was compiled.
