It is indeed quite complicated, so thank you very much for taking the time to answer every time! 😊

What I’m simulating is actually quite simple to describe: two cylinders rotating inside a housing filled with oil and air. I’ve also included bearings and a dynamic sealing in the setup.

In the colder areas, I’m using a conformal mesh. I’ve already checked all the boundary conditions, and none of them show negative temperatures or anything unusual.

I’m simulating with a constant oil density of 1060 kg/m³, which is quite high. For the dynamic viscosity, I’ve defined a temperature-dependent expression (e.g., 0.0848 kg/m·s at 15 °C). This property is already implemented as an expression. I’ve left the air properties at their default values.

Is there any other information I should provide to make my setup clearer?
