I am repeatedly getting the above mentioned error, no matter how I change the set of initial values and the boundary conditions. I am making my sample model in 2-D, a time dependent study using Conjugate Heat Transfer module. Can anyone spot the glitch here and help me out, kindly?

I was also having this kind of errors. In cases I was able to fix this by decreasing the Relative tolerance from 0.01 to 0.001. This way you solver will be more stable and won't blow up easily.
