Hello all,


Is it possible to define a non-constant fluid inlet temperature in Fluent? I'm running a transient simulation.
My inlet temperature depends on the temperature of a cell zone and I know what the inlet temperature should be at different temperatures of that cell zone. I need Fluent to interpolate the inlet temperature between the ranges and not change abruptly (which I could even do manually).



For example,


At 650C of cell zone, inlet temperature = 100C,
At 600C of cell zone, inlet temperature = 80C,
At 500!C of cell zone, inlet temperature = 55C,

...and so on.




Thank you!
