Default Thermal Simulation using Multiphase VOF model in Fluent

I am trying to run non-isothermal simulation using multiphase VOF model for simulation of high viscous polymer using air as a primary phase. I have included viscous heating in energy equation term but after some time, as I run the simulation, I usually get the error like temperature was limited in 6 cells etc. and simulation diverges immediately.

I could not solve this error.
If anybody has an idea to solve this problem, I would really appreciate.

And also, I could not find any tutorials for thermal simulation using VOF model in fluent.

Yours sincerely,
