time dependent analysis divergence problem

hello.
I am using COMSOL to perform a time dependent analysis and I am facing a situation where the resulting values over time do not converge (smooth continuous values).
The analysis is to calculate the temperature through Joule heating in a simple structure and I need to get a continuous and smooth value with respect to time. Even with a very small time interval, a few microseconds, the calculation shows a discontinuous change in slope at certain points as follows.
Is there any way to prevent this from happening with the time dependent solver option?
Thanks.
