Hi everyone.
I am beginner in openfoam, simulating a steady state conjugate heat transfer problem.

In this simulation, the residuals are decreasing up to some point, then they are oscillating periodically. I couldn't able to understand why this is happening.

Please explain if anyone knew about this phenomenon. The residual graph is attached here.
