Dear experts,

I need suggestions.

I have a simple cube (air_fluid) with a small inlet and a solid cylinder inside the cube. There is heat transfer from the fluid from the inlet to the solid (T_fluid=700K and T_solid=300K).

My question:
After some time (let's say after 2minutes), the temperature of the solid reaches 380K (threshold value). After reaching this threshold value, the temperature of the solid should increase as a step up to 700K.

I've done this in COMSOL using 'Implicit events'. How to achieve this fluent?

Thank you
